New Insecticides Registered in ND (08/01/19)

Sefina® Inscalis® Transform® WG

Sefina® Inscalis® (active ingredient afidopyropen, Group 9D) from BASF is registered for control of soybean aphids in soybeans. The rate is 3.0 fl oz per acre and there is a 7 day Preharvest Interval (PHI). Residual testing on Sefina® found that the residual was efficacious against soybean aphids for 21 days. The estimated cost of Sefina® is about $6.00 per acre at the 3.0 fl oz per acre rate.

Transform® WG (active ingredient sulfoxalfor, Group 4C) from Corteva is registered for use in the following North Dakota field crops:  alfalfa, canola, cereal crops (barley, oats, rye, wheat), field corn, dry beans, potatoes and soybeans. It will control piercing-sucking insect pests including aphids, leafhoppers, plant bugs and potato psyllids. Other crops and insect pests are listed on the label. It is now registered in the North Dakota State Department of Agricultural Pesticide Database. For soybean aphids, the rate is 0.75 -1.0 fl oz per acre and there is a 7 day PHI. An estimated pricing for Transform® WG is about $7.37 per acre at the 1.0 fl oz per acre rate.

Both Sefina® and Transform® WG are selective insecticides and control only certain insect pests. An advantage is their favorable profile to beneficial insects and bees. These products also provide a unique mode of action and are a good fit for resistance management of insect pests that are known to be resistant to other insecticide groups, such as pyrethroids, neonicotinoids, organophosphates and carbamates.
