Resistant Weed Management and Proper Application

Author: Robert Smith

Planning Unit: Nelson County CES

Major Program: Grain Crops

Plan of Work: Crop and Livestock Management and Marketing

Outcome: Intermediate Outcome

During this cropping year, a great deal of time was dedicated to educating clients on proper weed management strategies and pesticide safety.  It was in 2018 that two very nasty weeds began to emerge for the first time in our county that are resistant to the traditional cropping herbicide tools.  Palmer Amaranth and Waterhemp have been wreaking havoc in the midwest for a few years and have just now begun to be a problem for our farmers.  Many hours were spent both individually and in a group setting on how to properly scout and identify the weed in their most vulnerable stage.  Therefore, proper scouting, proper varieties, understanding the crop history, and understanding the new chemistry were all a must entering into the new cropping season.  In an effort to get ahead of the problem several articles were written on the topic and several discussions were had during our Extension Today radio show.  In the Spring of 2020 we educated just over 100 individuals on the proper application techniques for Dicamba and other herbicides.  Dr.'s Legleiter and Lee stressed the necessity to not rely on just post-application control of noxious weeds.
