What are some options to control volunteer XtendFlex soybeans in XtendFlex cotton fields?  This issue is something that we need to do research on as there is no data. As such in answering the question one has to rely exclusively on experience. Unfortunately, all the experience that I and my Midsouth colleagues have does not hint at a real good option to remove these volunteers. Continue reading →

Some of the earlier planted cotton fields will soon be entering the true “laying it by” application timing.  Given that some are clearly not successful spraying Palmer amaranth, goosegrass or junglerice with glyphosate + dicamba (Picture 1 and 2), going back to an “old school” layby is a good plan.

Judging by our research plots as well as walking some cotton and soybean fields most Pre applied herbicides are playing out about 7 to 10 days quicker than last spring (Picture 1).  The frequent rain would most likely be the reason for this. Continue reading →
