Coragen and Altacor, two new insecticides for the potato and fruit markets, have picked up federal registration for their shared new chemistry.
The two products, both owned by DuPont Canada, use the company’s Rynaxypyr chemistry, which the company said is the only active ingredient from the Anthranilic diamide class of insecticides and offers a “breakthrough” mode of action.
Coragen’s registration with Health Canada covers it for use on potatoes (both ground and aerial application) and on other brassica, leafy and fruiting vegetables.
It’s an important development for potato growers “who now have a new tool for managing Colorado potato beetles — even resistant biotypes,” according to Alex Crouse, DuPont sales manager. “Plus, it gives growers an effective and reliable option for European corn borer control.”

Altacor, meanwhile, is registered for use in pome fruit, grapes and stone fruit crops for lepidopteran pests such as oblique-banded leafroller, codling moth, tentiform leafminer, grape berry moth and oriental fruit moth.
The product’s environmental profile “makes it an excellent fit in integrated pest management programs,” DuPont product manager Jim Irish said in the company’s press release Monday.
The active ingredient, Rynaxypyr, works by disrupting muscle activity in insects, causing paralysis. Treated pests stop feeding soon after ingestion, become lethargic and lose mobility. The products offer ovi-larvicidal, larvicidal and adulticidal activity on chewing insects and other selected species, the company said.
The company said it worked co-operatively toward these registrations under the Organization for Economic Co-operation and Development (OECD) Workshare Project. Participating authorities such as Health Canada’s Pest Management Regulatory Agency worked together in the regulatory review, which led to an accelerated review and approval timeline for registration, DuPont said.
This Workshare process is a “significant” step toward getting new products to farmers quickly, the company said.
