IntroductionThe wheat variety guide summarises performance characteristics of commercially available wheats which have

undergone testing in the National Variety Trials Project (NVT), and Department of Agriculture and Food (DAFWA) wheat agronomy project. This information includes variety summaries, agronomic, disease and herbicide tolerance characteristics and medium to long-term yield performance. There is a review of regional NVT performance, time of sowing experiments and observed flowering dates in 2013. By combining agronomy research outcomes with other related wheat research this document provides current information to assist with variety choice and management for 2014. For more information on wheat varieties visit www.nvtonline.com.au.

Variety and agronomy for 2014

Disease – new leaf rust strain in WAUnusually high levels of wheat leaf rust on various resistant varieties, including WyalkatchemA, were observed in September and October of 2013. These reports came in from diverse regions including Northampton, Borden, Esperance and the Great Southern Region from Brookton to Hyden. Samples were sent to the Australian Cereal Rust Control Program’s (ACRCP) laboratories at the University of Sydney and a new leaf rust pathotype (strain) was identified. This pathotype (76-1,3,5,7,9,10,12 +Lr37) represents the first occurrence of virulence for the resistance genes Lr13, Lr17a, Lr17b, and Lr26 in WA.

It is speculated that this new pathotype of leaf rust moved to WA from eastern Australia last year on prevailing wind currents. This is a rare occurrence and only the second report of east to west movement of rust since 1990. The movement of rust from WA to eastern Australia via prevailing winds is more common. It is also possible that the new pathotype could have entered WA on someones’ clothing.

Implications: Varieties which carry the Lr13 gene (such as WyalkatchemA, CorackA and Emu RockA) and the Lr17a gene (FortuneA) are less resistant to the new leaf rust pathotype and will require additional management. WyalkatchemA and CorackA ratings have changed from RMR to MS and Emu RockA from R to MSS. Some varieties have other leaf rust genes that are expected to still be effective and will therefore have a lesser rating shift (King RockA, FortuneA and ZippyA). The impact of the new pathotype on MaceA is not apparent as yet. It has a gene combination including Lr13 that gives it its current MR status and tests are still continuing to fully understand its response to the new pathotype. In areas that are prone to leaf rust growers should be prepared for the chance that MaceA may respond as an MRMS or at worst as an MS in 2014.

Likewise, further tests are needed to establish responses of CarnamahA and CobraA which may also be vulnerable to the new pathotype.

Management strategies for the new rust strain:• destroy any volunteer wheat regrowth in leaf rust prone

areas, including those where leaf rust was found in 2013

• closely monitor crops and to ensure early identification, should rust be found, let other growers know through such means as Pestfax

• have a fungicide control plan

Disease – othersYellow spot and septoria nodorum blotch (including the widespread occurrence of glume blotch) were prevalent last year. Stubble from infected paddocks will be a source of inoculum for this season, particularly in continuous wheat. Disease incidence in the 2014 season will be dependent on the favourability of seasonal conditions and amount of inoculum carried over. If these diseases are present, and moving up the canopy, good results can be obtained with a single application of a registered foliar fungicide at or around flag leaf emergence to protect the upper leaves that contribute most to yield. In wheat on wheat situations, when early disease is severe, consider applying a foliar fungicide during tillering, around first node stage. A follow-up application around flag leaf emergence may also be required. Economic returns are most likely in environments where rainfall promoting disease development occurs in the weeks after fungicide application.

Two disorders which can be misdiagnosed as diseases were apparent in 2013. In MaceA, leaf yellowing can be mistaken for yellow spot. False black chaff can be mistaken for glume blotch in several varieties. These are not diseases and their occurrence is dependent on variety genetics and environmental conditions rather than inoculum carry-over. Because both disorders can be confused with diseases, it is important to pay particular attention to correctly identifying the cause of symptoms before using fungicides.

Table 3 provides the current disease resistance ratings for wheat varieties grown in WA. Additional information on diseases and disease management can be obtained on www.agric.wa.gov.au/cropdisease.

VarietiesBefore adopting a new variety it is important to consider why you want to replace existing varieties, and if the new variety will meet your needs.

Two new wheat varieties were released in 2013 for WA. HarperA and TrojanA are both mid to long season varieties with the potential to replace YitpiA. HarperA is an APW, while TrojanA is yet to be classified for WA. In 2013, TrojanA was the higher yielding of the two especially when yields exceeded 3t/ha. Refer to the regional summaries for additional information.

The area sown to MaceA has increased to over 50% of the WA wheat crop in 2013 (Table 17). This rapid adoption of MaceA is supported by the fact that the variety has been shown to consistently produce high yields compared to other varieties in the NVT trials over the last five seasons. MaceA also provides good disease resistance, grain quality and better tolerance to sprouting compared with other main competitors such as WyalkatchemA and MagentaA.

There are other alternative varieties released in the last five years that have shown specific areas of adaptation to warrant them being considered to either complement or provide viable alternatives to MaceA. The varieties and their likely roles that match their strengths are:

• MagentaA (APW) a mid-long maturing variety which is best suited to early sowing and where there is a high probability of yellow spot.

• Emu RockA (AH) is an early maturing variety that is the most competitive with MaceA at yields up to 2t/ha and so may have an important role in the lower rainfall regions.

• CorackA (APW) is competitive where it is likely that protein is restricted to APW grade and yellow spot is prevalent. Variable falling number and susceptibility to powdery mildew and black point make CorackA unsuitable for the higher rainfall coastal regions.

• CobraA (AH) yields best relative to MaceA in very high yielding scenarios and has also displayed better tolerance of yellow spot. CobraA has out-yielded MaceA on low pH soils where yields are above 2.5t/ha.

• EstocA (APW) is a later maturing Spear type wheat that is a rust resistant alternative to YitpiA with a possible yield advantage, particularly in Agzones 5 and 6.

• ScoutA (APW) and EnvoyA (APW) are earlier maturing Spear type wheats that are more competitive with MaceA in the south where yellow spot is less prevalent and sprouting tolerance is important.

• Justica CL PlusA (APW) and Grenade CL PlusA (APW) are imidazolinone tolerant wheats. Options for weed control puts them in a class of their own. JusticaA is better suited to the medium to high rainfall regions.

As potential YitpiA replacements, there is interest in the flowering dates of HarperA and TrojanA. These have been tested across a range of sowing dates in 2012 and 2013 (Table 14) in trials ranging from Geraldton to Esperance. In both years HarperA was slightly earlier maturing than YitpiA. TrojanA showed a marked difference between the two years. In 2012 it was similar to HarperA (a few days earlier than YitpiA), however in the cooler, wetter year of 2013 it flowered earlier and was midway between MaceA and YitpiA.

Refer to regional summaries for additional comments on varieties. More detailed information can also be found from the 2014 Crop Updates (C. Zaicou-Kunesch: Choosing the right wheat variety for the system).

Seasonal conditionsBe prepared for the season ahead. Conserving stored moisture through summer weed control can give greater certainty going into the cropping year and earlier sowing opportunities. Crop inputs should be used tactically where possible to avoid too many upfront costs which can increase losses if the season doesn’t finish strongly.

Seed qualitySeasonal conditions can have a significant and variable impact on the next year’s germination, early vigour and crop stand. Routine germination testing before seeding is recommended. Grain with lower germination produces seedlings with slower and more variable emergence. Replacing seed with less than 90% germination is recommended. Slight losses in germination can be compensated for by increasing seeding rates.

In general screenings were not an issue in 2013 but it is important to realise that although grain size has little or no effect on germination, small seeds result in seedlings that are less vigorous than those from large seed. Viable frosted grains should not be used as seed as they produce seedlings that take longer to reach the same seedling dry weight than seedlings from sound grain.

Grain weight can vary from season to season but note that the new varieties CorackA and Emu RockA, can have a larger seed size which can have an impact on reducing the number of plants established. Refer to individual trial summaries for the range of grain weights (www.nvtonline.com.au).

Minimise the impact of sub-optimal seed quality by adhering to the following guidelines:

• Grade seed to eliminate small seeds which are less vigorous but ensure seed handling is kept to a minimum.

• Avoid sowing too deep and where practical sow into warm moist conditions.

• Do not keep weather damaged seed for more than one season.

• Use fungicide seed dressings and pre-emergent herbicides such as trifluralin with care as they can adversely affect germination and crop establishment.

• Ensure that phosphorus levels available to the seed are adequate to maximise early vigour.

• Apply post-emergent herbicides at the correct growth stage.

Storage conditions and durationThe longer grain is stored, the more the seed germination and vigour is decreased. This decrease is largely dependent on seed moisture and the temperature during storage. The higher either of these parameters; the quicker seed viability declines. Grain moisture is likely to have a more profound effect on the germination of the grain than the temperature at which the grain is stored. For further information please refer to Farmnote 302/2008, Grain storage: Maintaining grain quality.






Agzone performanceAgzones have been developed through statistical performance to group together environmental regions that give similar crop performance. Agzones have been labelled 1 to 6 and are outlined in Figure 1.

Figure 1 Agzones of Western Australia

Long term wheat yieldsThe National Variety Trials (NVT) provides Estimated Genetic Values (EGVs) of grain yield for commercial varieties. Estimates of genetic value (yield) of individual varieties (on a state or region basis) are obtained from a statistical analysis of long term multi-environment trial (MET) data. These values represent the best available predictions for the specified region and are provided to facilitate reliable variety selection decisions (Table 1).

2013 Northern Agricultural Region (NAR) SummaryThe 2013 season had a good start in May, very low rainfall in mid-winter but above average rains in late winter and early spring. The dry conditions in winter reduced yield potential for many crops however the later rains were very important to maintain productivity at average to below average for many growers.

Staining was an issue for some growers in high risk areas but small grain screenings were not a major issue in 2013. In 2013, the longer maturing varieties performed better than the earlier maturing varieties, in general.

The majority of NVT’s in the Northern Ag Region were sown in the third and fourth weeks of May. These sowing times will reflect district practice in 2013. However some growers had sowed wheat into dry soil, which would have emerged in the second week of May.

NVT’s and new wheats in the NAR(Refer to Tables 4, 5 and 6)

AHIn 2013 MaceA was ranked first in four of the six NVT’s in Agzone 1 and all three NVT’s in Agzone 4. In Agzone 2, CobraA was ranked first in four of the seven NVT’s. Analysis of the NVT database (Zaicou-Kunesch, 2014 Crop Updates) indicates that CobraA yields better when sown before the end of May and in higher rainfall environments. However, CobraA is susceptible to low falling numbers following pre-harvest rain. Staining affected grain quality in CobraA but not MaceA, at agronomy trials in Binnu sown on 8 May.

Emu RockA was one of the lower ranked varieties in 2013 in all agzones. In contrast, in 2012 Emu RockA was one of the highest ranked varieties in Agzone 4. Sowing time of the NVT’s differed between 2012 and 2013. In 2012 the NVT’s were sown in the second week of June except at Yuna which was sown on 30 May. In 2013 the NVT’s in Agzone 4 were sown in the third and forth weeks of May.

APWMagentaA, CorackA and Westonia each have different maturities but were the highest ranked APW’s in Agzone 2, yielding similar or better than MaceA.

The NVT’s in Agzone 2 were sown in the last week of May and the late September rains benefited the longer maturing MagentaA.

CorackA did not rank highly in Agzones 1 and 4 in 2013 compared to 2012, when it was the highest ranked variety in Agzones 1 and 2. Staining is a risk for CorackA so May sowings should be avoided in districts with a higher risk of staining.

HarperA is a recent release, mid to long maturity APW from InterGrain. In its first year of testing in NVT’s, its yields were similar to ScoutA but significantly lower than MagentaA and MaceA in Agzone 2. It was not tested in Agzones 1 and 4.

APW-imiThe imi-wheats are not highly ranked in the NVT’s but provide a weed control option. In phenology trials in 2013 Grenade CL PlusA flowered two days earlier than Justica CL PlusA but similar to MaceA. Both clearfield plus varieties are susceptible to yellow spot leaf disease and staining.

Noodle wheatsCalingiri yielded 2% higher than FortuneA when averaged across all trials in each agzone in 2013. FortuneA has a better rust tolerance package than Calingiri but it is more susceptible to lower falling numbers after pre harvest rain.

Grain QualityScreenings were less than 5% for the majority of varieties in the NVT across all trials. Hectolitre weight (averaged across all varieties) was an issue at some sites. It was below 74kg/hl at Mingenew, Buntine, Dandaragan, Eneabba and Mullawa NVT’s. Hectolitre weights for EspadaA, Grenade CL PlusA, HarperA, Justica CL PlusA and YitpiA were below 74kg/hl (averaged across all NVT’s in the NAR). A full summary of grain protein, hectolitre weights and screenings are available on the NVT website.

SummaryIn 2013, the yield differences between the top ranked varieties were not as great as in the previous year. MaceA did rank consistently high but WyalkatchemA and MagentaA are suitable alternatives if the protein above 11.5% is not achievable for the AH grade.

MagentaA was ranked highly in all agzones in the NAR because it benefited from the late spring rains in 2013. Low falling numbers with pre-harvest rain is a risk for that variety.

CorackA did not rank consistently high in the NAR compared to previous years. Staining is a risk for that variety so it will be suited to low risk areas.

CobraA ranked highly in Agzone 2. Low falling numbers following pre-harvest rain will be a risk factor for CobraA in high risk areas.

2013 Central Agricultural Region (CAR) SummaryThe 2013 season began with late summer and early autumn rains over much of the Central Agricultural Region (CAR). The only exception was the eastern wheatbelt where little moisture was available for sowing and even up to mid-June. Germination varied from uniform and even on moist soils, to very patchy and uneven in dry and drying seedbeds.

A few severe frost incidents were observed in areas south and west of Merredin; however it did not result in many crops cut for hay compared to the damaging frosts in 2012. With the more favourable 2013 season, a bumper wheat crop was harvested with average to above average grain production in much of the region. Wheat yield varied from 1.0–2.5t/ha in Agzone 4, to 2.0–4.5t/ha in Agzone 2 and above 5t/ha in Agzone 3.

Hail damage and early November storms affected harvest in areas west of Merredin however most wheat varieties including the widely grown MaceA, maintained good grain quality. Grain quality was generally good at 80 to 84kg/hl. High screenings and low protein in high yielding wheat was a concern in some situations, however on-farm blending helped to achieve premium grade. There were a few reports of low falling numbers in Calingiri wheat due to the wet harvest.

MaceA was the most widely grown variety in the region. The popularity of MaceA is justified due to its adaption to regional environments, consistent high yields in the NVT system over five years, good disease resistance and delivery as an AH variety.

NVT’s in the CAR(Refer to Tables 7 and 8)

CobraA, CorackA, Emu RockA, MagentaA, ScoutA and the new releases HarperA and TrojanA had yields similar or better than MaceA in the 15 NVT trials throughout the region (Agzones 2, 3 and 4).

CobraA yielded well in 2013, yielding similar to MaceA in Agzones 2 and 4, and 14% higher in Agzone 3 (York and Narrogin), where the average yields were over 5t/ha.

Emu RockA, an early maturing AH variety, yielded similar to MaceA across the region except at Cunderdin, where MaceA significantly out yielded all the named varieties at that site. Emu RockA may be a good option for growers seeking an early maturing AH variety particularly in low rainfall areas (Agzone 4).

ScoutA was the highest yielding APW variety, outyielding MaceA by 7% across the region. CorackA was 5% higher yielding than MaceA in Agzones 2 and 4 but yielded similar in Agzone 3.

The new variety HarperA (APW) yielded 5% better than MaceA in Agzone 3 but was similar in Agzone 2. HarperA was not tested in Agzone 4.

New variety TrojanA was not tested in Agzones 2 and 4 but yielded the highest, 9% better than MaceA both at York and Narrogin (Agzone 3). TrojanA is yet to be classified in WA but looks promising for both low and medium rainfall areas in 2014 agronomy trials.

Influence of sowing time on yield of varieties: Wickepin Agzone 2 and Merredin Agzone 4(Refer to Table 9)

At Merredin grain yields averaged 2t/ha across all cultivars and three times of sowings. There where no significant effect of varieties or sowing time or the interaction on grain yield, probably due to the 2013 season at Merredin, in particular the good spring rainfall (Sep-Oct 63mm).

Similarly at Wickepin, May and June sowings had no significant effect on grain yield which was also due to the better than average 2013 season. But the effect of variety was significant.

Overall the new wheat variety TrojanA yielded the highest, averaging 17% and 8% better than MaceA at the Merredin and Wickepin sites respectively.

Although there was no significant sowing time by variety interaction, MagentaA and TrojanA were ranked the highest at the first sowing times at both sites. Conversely MaceA ranked the highest at the later sowings in June.

For comments on TrojanA’s maturity please refer to the introduction section.

2013 Great Southern and Lakes Region SummaryThe Great Southern and Lakes region were fortunate to experience an early May start to the season, following 60-70mm in April. However some crops may have struggled with the lack of rain in June. Rainfall varied throughout the region with deciles ranging from 1–5 during the season while the final growing season rainfall ranged between deciles 4–8. Rain in September was greatly appreciated, enabling the crops to finish well above their expected potential in many cases. A late frost occurred at the end of October which had a range of effects from no effect to a severe yield penalty or downgraded due to distorted grain.

HarperA and TrojanA were released in 2013. Both are mid to long season varieties with the potential to replace Yitpi. HarperA is an APW, while TrojanA is yet to be classified for WA (TBC).

Wheat variety performance in NVTs(Refer to Tables 10, 11 and 12)

AH/APW wheatWith the softer finish to the season and sowing times occurring in early to mid-May, other varieties ranked higher than MaceA in 2013. CobraA in comparison was consistently amongst the highest yielding varieties at 10 NVT sites in the region, except at Mt Madden. Results from previous seasons have suggested that CobraA performs better in high yielding environments and when sown before May 25 (Zaicou-Kunesch, Crop Update 2014). CobraA is susceptible to preharvest rain, hence low sprouting tolerance.

Interestingly, even with the relatively early start to the season in 2013, longer maturing varieties did not perform better than early maturing varieties. Mid May sowing at Wickepin resulted in Emu RockA, YitpiA and MagentaA having similar yields (Table 10). Frost can dramatically change this outcome but in 2013 the frost event occurred late. However at a specific time of sowing trial in Katanning, shorter maturing varieties such as Emu RockA and KunjinA had yield penalties greater than 0.5t/ha when sown in mid-May, compared with early-June (Table 12).

Rankings did change between sites but overall CobraA was the highest yielding in Agzone 2, followed by ScoutA, MagentaA, CorackA, HarperA and TrojanA (at one site), with Bonnie RockA last.

CobraA was the highest yielding variety in Agzone 3, but not significantly higher than MaceA or MagentaA (Table 10). Compared to other Agzones CorackA did not perform as well. Note: Results from Agzone 3 need to be treated with caution as Kendenup had site issues (Rhizoctonia).

In Agzone 5 MaceA, CobraA, CorackA, WyalkatchemA, MagentaA, HarperA and TrojanA performed similarly overall.

Noodle wheatFortuneA yielded similar to Calingiri in 2013. The noodle wheats where competitive with MaceA in Agzone 3, except for the shorter season YandanookaA (Table 10).

Soft wheatIn Agzones 2 and 3, both KunjinA and WedinA were competitive with MaceA (Table 10). With the earlier sowings in Agzone 5, only WedinA was competitive with MaceA (Table 11).

Grain QualityA full summary of grain protein, hectolitre weights and screenings are available on the NVT website. No major issues were present in 2013 although YitpiA, CobraA and HarperA did have problems with hectolitre weights below 74kg/hl at Hyden and Wagin.

SummaryOverall, MaceA remains a consistent, high yielding AH choice in the Great Southern and Lakes region. The softer 2013 season showed the dominance of CobraA which is prone to sprouting. APW types MagentaA, CorackA and Wyalkatchem are alternatives to MaceA, if protein above 11.5% is not met or with early May sowing opportunities in the case of MagentaA. The new mid to long season releases HarperA and TrojanA yielded higher than YitpiA, and yielded similar to MagentaA. The new releases have the advantage of better sprouting tolerance compared to MagentaA and rust resistance compared to YitpiA.

Effect of grazing on wheat varieties(Refer to Table 12)

Trials were conducted at South Newdegate and Kojonup to examine the effect of grazing (and sowing time) on a range of varieties. Plots were “snipped” to 3-5 cm at approximately 6 and 8 weeks after sowing, to simulate a heavy 2 week grazing period. At the mid to late May sowings the varieties showed no difference in their response to the simulated grazing treatment. There was no significant yield decline with grazing at Newdegate when sown mid-May but significant declines were found at the later sowing and at the higher yielding site at Kojonup.

Grazing did delay the flowering time by nearly one week with a rule of thumb of 2 days grazing to 1 day delay. Full report in Crop Update 2014 proceedings (Delaying wheat flowering time through grazing to avoid frost damage (Part 2: Incorporating varieties and sowing time)).

2013 South Coastal Agricultural (SCR) Region SummaryIn the 2013 growing season the southern sandplain enjoyed an early start, followed by above average winter rains. While parts of the sandplain suffered from waterlogging, the mallee was set up for one of the best years on record. Unlike previous years the spring rains were plentiful and the Esperance port zone achieved a record harvest.

MaceA is now the dominant variety of the SCR accounting for around 70% of the area sown to wheat.

With frequent rain and early sowing came higher levels of foliar disease than usual. The new strain of leaf rust to WA was detected in the area. This strain is virulent on varieties such as MaceA that rely on the leaf rust gene Lr13. The level of infection on MaceA varied across the port zone with the heaviest infection being in the Hyden area. Mace should now be regarded as being susceptible to leaf rust with the exact level of susceptibility yet to be determined. Routine fungicide applications for the control of yellow spot and the Septorias are likely to also control the new strain of leaf rust.

Harvest began very early and the region was largely spared any significant harvest rains. Most of the crop was harvested before rain arrived in mid-December and aided by drying winds, there were only isolated incidences of low Falling Numbers.

Performance of wheat varieties in the NVT’s (Refer to Table 13)

The rapid adoption of MaceA has continued and it is likely to be the dominant variety in the immediate future as no major alternatives have been forthcoming from the NVTs. Now that MaceA is susceptible to leaf rust it is likely that the most popular wheat in the region will be ‘MaceA plus fungicide’.

The other major variety in the region remains to be the later maturing YitpiA. While viable alternatives to MaceA have yet to appear on the horizon there are two promising new varieties of later maturity that may be considered as possible replacements for YitpiA. Both have improved rust resistance over YitpiA namely APW classified HarperA and TrojanA which has APW classification in eastern Australia but is awaiting a final classification in WA (TBC). Unfortunately neither variety is a major improvement for resistance to yellow spot. TrojanA has proven to be higher yielding than HarperA, especially at the earlier sown and higher yielding sandplain sites Neridup and Munglinup.

CobraA was not entered in the 2012 NVTs due to a seed mix-up. The 2013 trials confirmed data from other areas and years that had suggested that it is competitive with MaceA at yields over 2.5t/ha. CobraA’s susceptibility to low falling number (FN) and poor performance in the drier mallee region mean that it is unlikely to be adopted on the south coast.

Other early maturing varieties released in recent years include CorackA which continues to be competitive with MaceA for yield but not falling number. The other newer variety, Emu RockA once again yielded best in the lower rainfall mallee sites. The shorter growing season regions look to be Emu RockA’s area of best adaptation as it is at risk of low falling number if rain occurs near harvest.

In 2012 yellow spot (YS) was observed to be at very high levels of infection in wheat trials that were sown into canola stubbles. Further observations in 2013 suggest that it makes a great deal of difference which crop preceded canola. The highest levels of YS were observed where wheat had preceded the canola crop and much lower levels when it was barley or pasture preceding canola. If YS is being carried over on stubble for more than one year then a variety with the highest level of resistance should be chosen for the wheat:canola:wheat rotation.

Herbicide tolerance of wheat varietiesThe herbicide tolerance trials conducted over the last 14 years in WA indicate that some wheat varieties are more susceptible to damage from certain herbicides than others (Tables 15 and 16). The variation in tolerance may be due to differences in morphological or physiological characters and/or internal ear development stages among the varieties. The level of tolerance amongst varieties varies with the rate of herbicide, the environmental conditions when the herbicide is applied, and the stage of the crop growth. Seasonal variability makes it essential to test herbicide and variety interaction over several seasons and locations. The risk of crop damage from a herbicide should be balanced against the potential yield loss from both the weed competition and the number of weed seeds returning to the soil seed bank. Small yield reductions due to herbicide damage in sensitive varieties may not be easily detected at the paddock level, but over larger areas can be of great economic importance.

The herbicide tolerance of ten commonly grown wheat varieties in WA (Table 15) and nine recently released varieties (Table 16) are summarised using the following symbols. The herbicide and variety interactions are based on the yield response across herbicide crop tolerance trials conducted in WA from 1999–2013.

– Not tested or insufficient data

√ no significant yield reductions at the label recommended rates in (Z) trials.

N (w/z) narrow margin, significant yield reductions at higher than the label recommended rate, but not at the label recommended rate. Significant event occurring in w trials out of Z trials conducted. Eg (2/5) = tested in 5 trials, 2 trials returning with a significant yield reduction.

x% (1/z) yield reduction (warning) significant yield reduction at recommended rate in 1 trial only out of z trials conducted.

x-y% (w/z) yield reductions (warning) significant yield reductions at recommended rate in w trials out of z trials conducted.

A narrow crop safety margin implies that when spraying herbicide at the label rate under less than optimal conditions, herbicide damage and yield loss may occur. For example, when:

• overlapping herbicide

• spraying under wet conditions (for soil active and residual herbicides)

• there are stressed plants due to abiotic/biotic factors.

Herbicide tolerance of recent varietiesSince 2009, NVT advanced lines/varieties have been tested for herbicide tolerance in small plot (1.6m x 1.5m) screening trials at Katanning. The herbicides Boxer® Gold, Diuron + Dual®, Sakura®, Triflur® X, Glean®, Hoegrass® + Achieve®, Jaguar®, Affinity® + MCPA (Amine), Ally®, Diuron + MCPA (Amine), Tigrex® and 2 4-D LV ester 680 (xtra) are tested at higher than label rates. The majority of these herbicides were selected based upon their consistent damage (significant yield reduction) to wheat varieties in the previous trials. Boxer® Gold and Sakura® were included in the trials due to an expected rapid uptake of these herbicides for better ryegrass management. Any variety x herbicide/herbicides

combination(s) that registered significant yield reduction in the screening trials, are being tested in larger plot (10m x 1m) advanced trials. The testing is done at label and higher than label rates for at least two years to validate the results and to minimise the seasonal influences on herbicide tolerance. The results from the advanced trials on the new varieties are presented in the Table 16. Velocity® results on Scout are from another trial conducted at Katanning during 2013.

A. Important comments regarding safe use of herbicides

Sakura® 850 WG @ 118 g/ha is registered as a pre-emergent herbicide on bread wheat (not durum wheat) for the control of annual ryegrass, barley grass, silver grass, toad rush and annual phalaris. Sakura® could cause crop damage in situations which lead to an increased concentration of this herbicide in the planting row, or movement of the herbicide to the depth of the crop seed, which is similar to other soil active residual pre-emergent herbicides. Examples include the movement of herbicide treated soil into the seeding furrows due to wind or heavy rainfall soon after sowing, resulting in higher concentration of herbicide in the crop row. Another example is heavy rainfall between application and crop emergence on soils which have high potential for leaching, which may result in movement of the herbicide into the seed zone. For detail please see the Sakura® label.

The trial results (Table 15) indicate Sakura® at higher than the label rate caused statistically significant yield loss across the majority of varieties at Mullewa during 2011 and 2012 on sandy loam to loamy soils. A significant yield loss was registered even at label rate in 4 out of 6 varieties tested during 2012 at Mullewa. This could be due to a higher concentration of the herbicide in the seeding furrow or leaching into the seed/root zone as a result of a 26mm and 29mm rainfall event within a week of sowing during 2011 and 2012, and a single rainfall event of 34mm within a month during 2011. Another pre-emergent herbicide, Boxer® Gold, also responded similarly in the trials. When looking at occasional yield effects, it is important to remember that using grass herbicides in cereal crops often causes some crop effect, but the herbicides are being used to control weeds and the net return is a yield increase from weed control after any crop effect.

When using trifluralin, Yield®, Stomp® and Avadex®, ensure sown seed is placed below the herbicide treated soil band; otherwise severe root retardation may result. Surface crusting may exacerbate emergence problems. Old seed with reduced vigour, varieties with short coleoptiles, and seed dressings that reduce coleoptile length should be avoided. If sowing with knife points, and using higher label rates, ensure that treated soil does not get thrown, blown or washed into the furrows.

Diuron 1.0L + Dual® (Metolachlor 720g/L) 0.5L/ha have been reported to cause more crop damage on lighter than heavier soil types. If using knife point and press wheels to sow the crop, apply this mixture pre plant only (0–7 days) as knife points leave open furrows/slots. Crop damage can result if herbicide is washed into the furrows. If using a ‘Full Cut’ seeding system, that leaves a relatively smooth surface, this mixture can be applied post plant preemergent within 3–4 days of planting.




Metribuzin 150g a.i./ha is registered as a preemergent herbicide on Eagle RockA wheat. To achieve good control of annual ryegrass and barley grass, Treflan® 480 @ 1.0L/ha can also be mixed with the recommended rate of metribuzin. The trial work has indicated that a two way mix of metribuzin 150g a.i./ha (e.g. Lexone® 200g/ha) with Diuron 1.0L or Stomp® 330E 1.0L or three way mix with Diuron 1.0L and Dual® Gold 250mL/ha was safe on this variety. Any weed escapes, especially brome grass after metribuzin use could possibly be controlled/suppressed, by application of Monza® @ 25g/ha at 2–3 leaf or Atlantis® @ 330mL/ha at 3–4 leaf stage of the crop. Do not use metribuzin (alone or in mixture with other herbicides) on the other wheat varieties (e.g. Carnamah), as large yield reductions have been recorded in the trials. Moreover metribuzin at 150g a.i /ha is registered for use on Eagle RockA and Blade only.

Where marginal zinc and copper deficiency conditions exist, Glean® and Logran® may aggravate such deficiencies.

B. Safe timings for phenoxy herbicides’ application

MCPA, 2,4-D and dicamba are the main phenoxy herbicides used in wheat. The timing of their application is much more critical than for other herbicides. These herbicides often produce morphological abnormalities in both the vegetative parts and ears of wheat plants.

Wheat tolerance to these herbicides depends on the stage of ear development. Wheat is most sensitive to these herbicides at the double ridge/floral initiation stage of ear development. At this stage, cells change from producing leaves and begin to form the ear. The embryonic ear continues to form until the ‘terminal spikelet’ stage is reached.

Spraying advice is based on leaf and tiller development, but not all varieties have the same correlation between leaf/tiller and ear development. Thus different varieties become safe to phenoxy spray at slightly different growth stages. Long season varieties take longer to reach the safe stage.

To use higher rates of MCPA amine (2.0L/ha) and 2,4-D amine 625 (1.3L/ha) in Amery, AxeA, Bonnie RockA, CobraA, Emu RockA, EspadaA, King RockA, KunjinA, MaceA, Tincurrin, Westonia, WyalkatchemA, and ZippyA apply these herbicides at Z15-Z16 (5–6 leaves on the main stem); in Brookton, BumperA, Camm, Carnamah, EGA Eagle RockA, FortuneA, MagentaA, ScoutA, Stiletto, YandanookaA and YitpiA at Z16Z17, and in EndureA, Calingiri and Spear at Z17-Z18. At these stages floral initiation will be completed in the above varieties.

Do not apply these phenoxy herbicides between flag leaf emergence and the soft dough stage on any variety. Generally MCPA amine is safer than 2,4-D amine especially on later developing varieties.

Dicamba (and mixtures with 2,4-D or MCPA) should not be applied after Zadoks 30 (pseudo-stem elongation, but first node not yet above soil surface).

The previous trial results indicate that caution should be used if applying phenoxies in dry seasons when there is moisture stress. Brookton and Calingiri were found to be more sensitive to phenoxy herbicides than the other varieties under moisture stress conditions.

As several wild radish populations from the Northern Agricultural Region have been confirmed resistant to phenoxy herbicides, rotate the phenoxies with other herbicides or apply as a mix with other herbicides at full rates to keep these herbicides working.

C. Waterlogging and crop safetyA number of products, including Group A and B herbicides are tolerated by wheat because they are metabolised within the seedling. If a seedling’s growth is retarded by waterlogging, cold or any other factor, its metabolism is reduced, and toxic levels of herbicide can accumulate within the plant. There were many cases of such damage in 1999.

There were also many examples of trifluralin reducing emergence when the paddocks were waterlogged. It is suspected that this was due to increased uptake by the coleoptile from the wet soil. If there is any chance of extreme waterlogging just after seeding, crop damage is more likely, and farmers should consider using safer products, or spraying post-emergence.
