I know this has been a frustrating planting season to say the least.  Replanting has been more the rule than the exception this spring.  There have been reports of fields that were first planted to corn then replanted to cotton and now will likely be replanted to soybean. With all the troubles planting and replanting this spring please do not forget to manage Palmer amaranth or you may have to replant yet again just to control the pigweed.  These June weather conditions are shaping up to be a perfect Palmer amaranth storm!  Continue reading →

Some reports of ineffective burndown applications to winter annual cover crops (winter wheat, cereal rye, hairy vetch, crimson clover, etc.) have been coming in.  Even in our research at the West Tennessee Research and Education Center cover crops have proven difficult to control with a single pass of the sprayer.  Paraquat and glyphosate are the typical go-to herbicides for this type of burndown application, but neither has proven consistently effective this spring.

Palmer amaranth started emerging last week.  Some of it is ½ to a 1” tall today April 22. Of course this is just the vanguard of the Palmer that will be coming.  Despite this early Palmer flush typically being less numbers per foot than later emergence events, it is the most important emergence event to control.
