Vegetable, berry and tree nut producers are expected to benefit from expanded labels for a pair of Group 28 insecticides.
DuPont Canada on Monday announced it has picked up expanded registrations for Coragen and Altacor, both of which feature Rynaxypyr, an anthranilic diamide (Group 28) product that the company says can help crop growers keep resistance in check by rotating pesticide chemistries.
Coragen, already used by potato, brassica vegetable, fruiting vegetable and leafy vegetable growers, will now be allowed for use in other vegetable crops such as sweet, field and seed corn, tuberous and corm vegetables, cucurbit vegetables and alfalfa.
Berry producers, meanwhile, will now be able to use Altacor for control of raspberry cane borer and raspberry crown borer in caneberry crops such as raspberries and blackberries.
The Altacor label has also been expanded for use against codling moth, oblique-banded leafroller and three-lined leafroller in tree nut crops.
Altacor is already registered for use against certain pests in grapes, pome fruit crops (apples, crabapples, pears) and stone fruit crops (peaches, apricots, plums) and blueberries.
“Resistance to existing chemistries in various crops is a concern because of the multiple generations and the insecticide applications needed to keep pests under control,” Jim Irish, specialty products manager for DuPont, said in the company’s release Monday.
Both products, he said, can control “economically significant pests and are effective at multiple stages of the life cycle.”
