Weeds: END OF SEASON WEED CONTROL REMINDERS

| Leave a comment

written by Dr. Jeff Stachler, Weed Scientist, UMN and NDSU

Scouting fields for weeds throughout the growing season is extremely important to maintaining herbicide effectiveness and planning for future weed control decisions. Scout fields now and at harvest to determine the effectiveness of this season's weed control practices. If weeds are present now, determine why they are present. If weeds are present due to herbicide resistance, then weed control and cropping practices must be different next season and beyond.

What does soil quality mean? Why is it so important? How do we measure it and how can we impact soil quality with our management practices? Hear experts from the University of Minnesota, Ohio State University, the USDA-Agricultural Research Service, and the USDA-Natural Resource Conservation Service address these questions and more at the "Soil Quality Workshop". This program will be held at two locations: Monday, September 12 at the West Central Research and Outreach Center in Morris, and Tuesday, September 13 at the Southern Research and Outreach Center in Waseca. Each workshop will start with check-in at 8:00, with the program running from 8:30 to 4:30. This program is sponsored by U of MN Extension, The Ohio State University, the Minnesota Department of Agriculture and North Central Region Sustainable Agriculture Research and Education.

Questions about which soybean diseases will be problems this year in Minnesota come up often. Although there are no good predictive systems, the wet weather conditions this summer are favorable for sudden death syndrome (SDS) and Phytophthora root and stem rot.  Phytophthora rot occurs across MN.  SDS occurs most often in southern MN, but appears to be spreading north each year.

Goss's leaf blight and wilt of corn is a damaging disease that is new to Minnesota and has caused problems in fields over the past two years.  The weather conditions this summer may favor development of this disease again.  It was reported from two fields in southern MN in the past week, and it may be starting to develop in many fields.  This is a disease to watch for across Minnesota. If you see infected plants, please send infected leaf samples for a new research study as described below.
