[8/10/2016] Insecticides are an important tool in the IPM toolbox for protecting crop yields from pests. However, we need to keep in mind that many of the insecticides we use to manage crop pests are also toxic to beneficial insects, such as predators and pollinators. This article will provide an overview of some considerations for reducing the risk of impacting pollinators (e.g., bees and some flies) when foliar insecticide applications are made to crops.
[8/3/2016] History has shown us many times that over-reliance on pesticides often results in development of pesticide resistance in pests. Last summer in parts of southern Minnesota, some pyrethroid insecticides (bifenthrin [e.g., Brigade, Tundra , Hero and others] and lambda-cyhalothrin [e.g., Warrior and others]) failed to provide adequate control of soybean aphid. Historically, these have been among the top performing pyrethroid insecticides for soybean aphid management. Follow-up laboratory bioassays confirmed resistance (10- to 44-fold resistance) to these insecticides in a soybean aphid population collected near Lamberton, MN.
