Dow AgroSciences Canada has picked up registration for Delegate WG, a new “reduced-risk” insecticide it will market this year in Canada’s fruit- and vegetable-growing regions.
Delegate is a Group 5 insecticide to control foliar feeding pests. Its active ingredient, spinetoram, is created through fermentation and then modified for a new mode of action, Dow said in a release Thursday.
Delegate’s label covers it for insect control or suppression in a number of crops but its target market will be fruit and vegetable producers, for control of pests such as codling moth, Oriental fruit moth, leafrollers, leafminers, diamondback moth, cabbage loopers and armyworms.

Australia nears breakthrough canola deal with China, sources say
Canberra is close to an agreement with Beijing that would allow Australian suppliers to ship five trial canola cargoes to China, sources familiar with the matter said, a move towards ending a years-long freeze in the trade.
At the same time “we’ve conducted dozens of field trials in key crops and found that Delegate has low impact on populations of predators, including big-eyed bugs, damsel bugs, ladybugs and lacewings,” said product manager Mark Woloshyn in Dow’s release.
Delegate’s “natural” origin qualified it to be classified by Health Canada’s Pest Management Regulatory Agency (PMRA) as a reduced-risk pesticide, the company said.
Spinetoram is derived from the fermentation process used to make two other Dow insecticides for horticulture producers, Success 480SC and Entrust 80W — the latter of which is registered for use on organic crops, said Dow spokesman Stan Audette.
Although applied at a low rate and offering a low impact on beneficial insects, Delegate will control target bugs both on contact and by ingestion, acting on the insect’s nervous system, the company said.
