The 2015 MSU Weed Science Research Results have just been posted to MSUweeds.com. The results for each study show our weed control ratings by species, any crop injury observed and crop yields when taken. The results also detail all of the application information.

Mark your calendars for Tuesday, December 15th to attend the 2015 Integrated Crop and Pest Management Update at the MSU Pavillion. More details and online registration can be found in Michigan State University Extension link below.
2015 Integrated Crop and Pest Management Update
October 2nd, 2015
If you suspect that you have herbicide resistant weeds in your fields, now is the time to collect seed and have it tested. This week I began my new role as the Weed/Herbicide Diagnostician with MSU Diagnostic Services. One of my main responsibilities is continuing the herbicide resistance screening that has been conducted in Christy Sprague’s laboratory the past several years. The Michigan Soybean Promotion Committee has agreed to continue to suplement the costs of this testing for soybean growers so that they may submit samples free of charge. Species that are eligible for the free testing include amaranth species (Palmer amaranth, common waterhemp, Powell amaranth), maretail/horseweed, common and giant ragweed, and common lambsquarters. A minimum of 5 plants with mature seed present should be collected, stored in a sealed paper bag and mailed or brought into Diagnostic Services (578 Wilson Rd., Room. 107, East Lansing, MI 48824-6469). Please also send in a completed form with your submission (MSPC resistance screen form).
The turn around time for results can be 2-3 months to allow us to clean samples, break seed dormancy, grow and treat seedlings in the greenhouse, and assess control.
Stay tuned as I develop some photos and other materials to ensure the best collection of samples.
Recently this topic has been in the MI news:
Consider collecting seeds from weed escapes if you think they may be resistant to herbicides -MSUE, Bruce MacKellar
Also, stay tuned for a video that Christy Sprague and I recorded with MSPC this week further detailing detecting and confirming resistance.

Here are a couple photos from our first of two sugarbeet harvests yesterday up at the Saginaw Valley Research and Extension Center.

Tying the sample bags atop a moving harvester takes some creative tactics.
