Argentine stem weevil Argentine stem weevil (ASW)larvae and adults feed by tunneling into leaf stems and growing points of new seedlings. This damage severely restricts seedling development and growth of the crop, causing stunting and plant death.
Aphids in brassicas, untreated vs treated Aphids in plant crown
AphidsAphids are found on the underside of leaves and in the crown of the plant where the plant is most vulnerable to damage. Aphids suck the sap from plants causing wilting and stunting, leading to reduced plant vigour and dry matter yields. Aphids are also vectors for several viruses that severely impact growth and bulb development.

Springtails Springtail attack begins as soon as the seedlings begin to emerge. Feeding can sever the stem, destroy the growing point, or totally defoliate seedlings. Tank mixing an insecticide (eg. Dew™ 600) with WeedMaster® TS540 at sprayout, plus sowing treated seed or insecticide granules should always be the first option for springtail control. If springtails become a problem after seedling emergence, apply Attack.

Leaf miner larvae tunnelling in leaf vein.
Extensive Leaf miner damage
Leaf miner Leaf miner larvae live within the leaf tissue, creating tunnels in the leaf and often damaging leaf veins. The damage caused by tunnelling larvae reduces the photosynthetic activity of the plant and causes premature leaf senescence and death. Plant leaf growth is reduced leading to decreased crop yields. Leaf miner is a grossly underestimated pest in brassicas, especially turnips and swedes. Controlling leaf miner with multiple Attack sprays throughout the life of a crop has been shown to increase yields by up to 2.3 tonnes of dry matter per hectare.

Application Apply Attack in at least 100 - 300 litres water/ha. Use the low rate on young crops and the higher rate when the crop has reached canopy closure. For aerial applications, use the lower water rate. The use of a non-ionic wetting agent such as Contact™ Xcel (25 - 50ml/100L water) is recommended to improve coverage, especially when spraying for aphids and caterpillars.
NOTE: Avoid tank mixing Attack with herbicides unless compatibility and crop safety is known. Contact your Nufarm representative for further information.
Stock withholding period Attack has a 7 day withholding period for grazing animals. Sheep and deer should be held from slaughter for 7 days if fed crops treated within 7-14 days of application.
TimingFor early control, add Attack to the tank mix when spraying for broadleaf weeds and grasses (provided compatibility is known). Attack should be applied when insects first appear or when damage becomes visible. Repeat applications may be necessary during the growing season as these pests have highly mobile stages and re-invasion can occur. It is important to monitor the crop at least weekly for pests throughout the season.
Economics of using Attack to control pests Trials have shown that controlling pests, particularly leaf miner, in brassica crops greatly improved yields and was very cost-effective. Between 0.5 and 2.3 tonnes of extra dry matter per hectare was grown at a cost of only 4-8 cents per kg DM.
Attack is the best form of defence
The importance of pest control in fodder brassicas and fodder beet Pests can severely damage crops, reducing productivity and resulting in poor quality crops. Major pests thrive if uncontrolled and can cause devastating damage, reducing dry matter production which is costly. What is Attack? Attack is an easy to use, broad spectrum insecticide for use in fodder crops to control all major pests including leaf miner, aphids, Nysius (wheat bug), springtails, Argentine stem weevil and the caterpillars of diamondback moth and white butterfly.
Two insecticides in one• Attack contains both permethrin (25g/L) + pirimiphos-methyl (475g/L) for an effective kill. How does Attack work?Attack works in five different ways to protect your crop:• Contact - pests killed by contacting sprayed foliage• Ingestion - acts as stomach poison when sprayed foliage is eaten • Fumigant - vapours kill pests • Translaminar - moves through leaf to kill pests inside and underneath the leaf • Repellency - repels pests from the sprayed plant.
