Fall scouting for soybean weed management
Understanding what weeds made it through this year’s program and why they survived will help increase weed control next year. Extra time this fall can also add money to your pocket next fall. Dr. Mark Loux’s research showed a 16 bushel increase from proper management of marestail in soybeans. That is $210 extra dollars in your pocket at today’s prices. While you are out scouting fields keep an eye out for your local extension educator. We will be out doing our annual fall weed survey and seeing what weeds made it through this year’s herbicide program. The last few surveys have shown that in most counties marestail, giant ragweed, and volunteer corn make up the top three weeds that survive until fall. For more information on what to look for in the field Dr. Vince Davis, Weed Management Specialist for Univ. of Wisc. has a three part series on fall scouting. Part I, Part II, Part III. Also when making plans for weed management be sure to consult the Ohio and Indiana Weed Control Guide available from the Agronomic Crops website at http://agcrops.osu.edu under publications.
