Cobalt Insecticide Registered
Cobalt, an insecticide manufactured by Dow AgroSciences LLC, has been registered for use to control insects infesting certain field, fruit, nut, and vegetable crops. The active ingredients of Cobalt are chlorpyrifos (the active ingredient of the organophosphate Lorsban) and gamma-cyhalothrin (the active ingredient of the pyrethroid Proaxis). Cobalt is registered for use in alfalfa, corn (field, sweet, seed), grain sorghum, soybean, and wheat, as well as in a few other crops. The efficacy of Cobalt against soybean aphids in our trials has been excellent.
Please refer to the label for rates of application, directions for use, precautions, and restrictions. Cobalt is restricted for use by certified applicators.--Kevin Steffey
