Spider Mite Activity in Corn and Soybeans This Week

I have received a call from one of our Pest Pros scouts in the Grand Marsh area indicating that he was finding spider mites in both corn and soybeans. I also received a call from our Agronomy Advisor in Galesville letting me know that they are starting to find a few spider mites in the Trempealeau area. The following links contain documents on spider mites and products that you could use to control them. Please let us know if you need any help check your fields for these pests. Thank you.

White Mold Found in Grand Marsh

Our Agronomy Manager was checking on one of his irrigation systems last night and he found some white mold in his soybean field.    Please be on the watch for this disease, especially in our irrigated soybean fields.  Below is a photo of white mold taken last year near Galesville.  For more an informative article on white mold from the North Central Soybean Research Program, click the below link.  — Rob Shields

Info Ag Conference

We made it back from St. Louis, Missouri last night. We took in the annual Info Ag conference to learn more about the new technologies available for our industry. There were a lot of displays and vendors talking about in season imagery and the use of drones in agriculture. My favorite session was a talk by Dr. Raj Khosla from Colorado State University, he went over Variable Rate prescriptions and how it is important to take a holistic approach to include nutrients, water, seed, soil type, field history, in season imagery, etc. I also enjoyed hearing from a cooperative in southern Ontario discuss how they use drones to evaluate fields in season to help their growers look for issues in their fields. Please let us know if you would like to learn more about the Precision Agriculture services offered at Allied Cooperative. — Rob Shields, AgronomistIMG_20140729_123137218
