Q&A on Terminating Cereal Rye, Applying a PRE

April 25, 2018
A grower asked: My cereal rye cover crop is only 3 to 5 inches tall going into planting season. Can I combine two field operations in one by applying glyphosate to terminate cereal rye and tank-mixing it with a residual herbicide for early season weed control?

Timing of Cover Crop Termination and Related Factors

April 20, 2018
Should the cold spring delay cover crop termination? Growers walk a fine line between growing cover crops long enough to get the biomass they want without reducing yield in the following grain crop. This discussion from an agronomist, entomologist and weed scientist looks at various factors to consider.

Pre-emergence Residual Herbicides are the Foundation of Soybean Weed Control

March 29, 2018
Even with new dicamba-resistant soybeans, pre-emergence, residual herbicides are needed to mitigate yield loss due to weed competition, provide a longer time for soybean to establish, and reduce selection pressure for weeds resistant to post-emergence herbicides.
