U.S. EPA has granted a Section 3 label for the DuPont insecticide Avaunt for control of major worm pests in head and leaf lettuce, cabbage, broccoli, cauliflower, tomatoes, peppers, sweet corn (whorl applications only, apples and pears.
Registration applications have been submitted to California and Arizona for review and approval.
Avaunt is a low-use-rate product that provides growers with a new tool for integrated pest management and resistance management.
After ingestion, Avaunt has a unique mode of action, making it particularly helpful in resistance management. It works by inhibiting sodium ion entry into nerve cells, resulting in paralysis and death of target pests. Cessation of feeding occurs in four hours or less.
In vegetables, these pests include armyworms, cabbage looper, corn earworm (in lettuce), diamondback moth, imported cabbageworm, tomato fruitworm and tomato pinworm. In apple and pear crops, susceptible insects include plum curculio, codling moth, Oriental fruit moth, lesser appleworm, redbanded leafrollers, tufted apple bud moth, white apple and potato leafhoppers, tarnished plant bug and apple maggot.
Avaunt is formulated in a water-dispersible granule containing 30 percent active ingredient. At labeled rates, it can provide from five to 14 days of residual protection of treated leaves and fruit, depending on the insect, population pressure, crop and environmental conditions. It does not protect new growth.
