Spraying is now completed at the two trials sites and Dewar Crop Protection has carried out the final weed assessments. The untreated plots are now really interesting, highlighting the difference in the weed spectrum between the two sites. On 6 June the Yaxley site had a visit from a ‘Drone’ courtesy of Sam Myhill and it is just possible to pick out the trial and the untreated areas within the field, Photos 1 and 2.
Initial results from the Mendlesham trials site
In earlier updates the number of cleavers present at this site has been highlighted and those visiting have generally been impressed with how well herbicide programmes have worked, plus and minus triflusulfuron-methyl. In particular the 2 spray ‘Broadacre’ programme based on BETASANA TRIO has been very effective, Photo 3 shows an untreated area and Photo 4 a BETASANA TRIO ‘Broadacre’ plot.

21.05.15 BETASANA TRIO 2.0 + Debut 30g + Venzar 0.4 + BETTIX FLO 0.5 + Oil
In the UPL winter technical meetings we will compare costs and statistical differences between programmes which will also take into account the number of times plots were sprayed.
Initial results from the Yaxley trials site
The dominant weed species at the Yaxley site was black-bindweed (Fallopia convolvulus), the % control of this weed from some of the programmes within the trial is shown in Graph 1. The BETASANA TRIO programmes worked very well but the inclusion of oil was definitely benefical, it was also interesting to see how well again the BETASANA TRIO ‘Broadacre’ programme performed. Statistics on these results will be provided at the autumn technical meetings. Photo 5 shows an untreated plot at Yaxley.

Insecticides for use in the sugar beet crop
There is often confusion as to what insecticides can be used in the sugar beet crop and if a product can be used against a particuar target pest that does not appear on the label.
A very useful document is ‘Pesticides and Cross Compliance’ – regulatory update 15/2007 which was updated on 5 February 2008 and then further amended on 30 October 2014. This was produced by CRD and is available on their web site or email [email protected] for an electronic copy.
In response to the initial question, the identity of the target pest is not part of the conditions of used specifically stated on the Notice of Approval. There is therefore no reason why an approved product cannot be used against a pest, disease or weed which is not stated on the label, providing that all the conditions of use and any other specific direction on the label or within the Notice of Approval are complied with (e.g. maximum dose, crop, timing etc).
However, manufacturers cannot be held liable for losses or unsatisfactory performance associated with control failures if the label does not explicitly offer control of a target pest that is not listed.
TOPPEL 100 currently marketed under MAPP number 15696 has the following label requirements for sugar beet (Table 2). Permasect C and Hallmark Zeon are included for comparison.

Silver-Y-Moth control in beet crops
TOPPEL 100 can be used for controlling silver-Y-moth caterpillars. Treatments should begin as soon as the threshold is reached which is currently 5 caterpillars per beet plant. Damage from silver-Y-moth caterpillars can be rapid and caterpillar numbers difficult to count so it pays to be vigilant and check crops regularly. Water volumes should be kept high i.e. 600 litres/ha. Heavy rainfall or irrigation can also be effective as they will wash caterpillars off the plants on to the soil.
Leaf miner control in beet crops
TOPPEL 100, Permasect C and Hallmark Zeon can be used for leaf miner suppression in sugar beet but to be effective, the insecticide needs to be applied at the egg hatch stage.
UPL trials visits – last chance on 9 July to visit
The trials sites have now been visited by a large number of people, one of the final visits will be on the morning of 9 July when UPL and British Sugar will be hosting local farmers if you are interested in joining this visit then please contact Pam Chambers via email ([email protected]) or mobile (07809 227 583) or Guy Bicknell via email ([email protected]) or mobile (07702 541 561).
On 11 July the untreated areas within the trials will be destroyed to minimise weed seed return to the sites. A big thank you to our two host farmers this season Ian Downie from Mendlesham and David and Richard Hammond from Yaxley and of course to the long suffering Dr Alan Dewar and his Dewar Crop Protection Team for carrying out all the hard work, without them we would not have had such successful trials. Also thanks to two local farmers Russell Lummis and Gordon Talbot for helping with site selection.
