Minnesota Crop News has published an article on palmer amaranth.

[8/17/2016] A new study published by Anh Tran, Tavvs Alves & Bob Koch, has found Sulfoxaflor to be less harmful to beneficial predators of soybean aphids.

[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. 

[8/8/2016] Growers now have access to two more miticides for use against twospotted spider mites in soybean. These miticides are Agri-Mek SC (Syngenta) and Zeal SC (Valent). These are welcomed additions to the limited suite of chemicals for management of twospotted spider mites in soybean. They represent insecticide groups (modes of action) not used for soybean aphid. 


[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.
