With barley harvest occurring and wheat coming off soon after, double-crop soybean planting will soon follow in some areas of the state. Weeds are generally less of a problem in double-crop soybean because of the delayed planting date. But even with fewer weeds emerging, when they are present and in combination with potential dry weather, impacts on yield can be noticeable. A weed-free start is one of the most critical aspects of weed management in double-crop soybean. One of the biggest weed concerns is in managing glyphosate-resistant marestail or horseweed. Some of these populations may also be ALS-resistant. Marestail that are cut off during small grain harvest will recover, branch out, and probably be even more difficult to control. In full season soybeans, we have been strongly advocating the use of 2,4-D LVE in the burndown program. However, most growers are not willing to wait the necessary 7 days after 2,4-D application in double-crop. So, what are the options?
