A number of calls have come in about options to control large Palmer in full-season soybeans. The beans are 30 to 36 inches tall and the Palmer amaranth plants are poking through the canopy. In most cases the field has been sprayed with glyphosate. There are no good options. Late-season Palmer amaranth management needs to focus on stopping seed production, and chemical choices are likely to be ineffective.

Remove Weeds Before the Seeds Mature
Many weeds have started to flower in the past week or two. Weeds, depending on the species, will continue to flower from now until frost. I am often asked how soon after flowering are the seeds mature. We have some ongoing trials looking at this issue, but we have a few preliminary results to share.
First and foremost, seeds are mature shortly after flowering. By this I mean that within two weeks of flowering, the seeds on some plants are capable of germinating and contributing to the weed seedbank. So if you are pulling weeds (or mowing them or spraying them) to stop them from producing seeds, you should physically remove the weeds from the field because they may already have mature seeds.

Weed Control Options for Double Cropped Soybeans
With small grain harvest underway, there are some questions about preplant weed control with double cropped soybeans. This has always been a challenging situation, and with the presence of herbicide-resistant weeds, it has become even more complicated and results are often less than satisfactory. Larger plants that have been cut off or damaged by the combine are going to be less susceptible to herbicides and achieving 100% control will require a lot of environmental factors falling in your favor — the recent dry spell does not work in your favor.

Postemergence Management of Glyphosate-Resistant Horseweed in Soybeans
Options for controlling horseweed (marestail) resistant to glyphosate after the soybeans have emerged are very limited. Liberty Link soybeans are an exception, because Liberty 280 is fairly effective on horseweed (be sure to keep your rates up and keep spray volume up to ensure good coverage). [Read more…]
