I’ve received several calls this week requesting information on whether or not to keep injured cotton and management after the injury. In this brief article, I will cover the ‘keep or discard’ decision and briefly cover best management practices after the decision to keep the crop has been made.

That information is beyond the scope of this article but should be available from your insurance agent or attorney. Continue reading

Other folks have asked about cleaning up just a sundry of different broadleaf weeds like henbit. Fortunately, there are two “new” herbicides that have been recently labeled in wheat that can help on these broadleaf weeds. Continue reading
