  • Foliar applied insecticide control of the Soybean Aphid (2011)
    During 2011, the performance of insecticides on the soybean aphid, Aphis glycines (SBA), was evaluated at the University of Minnesota Southwest Research and Outreach Center near Lamberton, MN. Twelve (12) insecticides and two untreated controls were compared with in a randomized block design with four replications. The insecticides evaluated were: pyrethroids (alpha-cypermethrin, Baythroid XL, Hero, Tundra EC, and two rates of Warrior II); a neonicotinoid (Belay); an organophosphate (Lorsban Advanced); pyrethroid plus neonicotinoid premixes ( Endigo ZC, Leverage 360, Brigadier); and a pyrethroid plus organophosphate tank mix (Baythroid XL + Lorsban Advanced). The insecticide treatments were applied on August 3, 2011 to R4 stage soybeans. The SBA population was approximately 250 aphids/ per whole plant and evenly distributed throughout the trial area at this time.
