Residual Herbicides Best Suited to Spring Marestail Management

May 2, 2018
Marestail, also called horseweed, is sensitive to most herbicides labeled for its control early in its growth stage, i.e. the rosette stage. Delaying treatment can allow it to compete with corn and soybean, potentially causing significant yield reduction.

Figure 1. Cereal rye planted as a cover crop in many fields is slow-growing this spring. Combining a cover crop termination and PRE application may be a valuable time-saver this year, if used correctly.

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.

How Temperature and Rain Can Affect Burndown Herbicides

April 3, 2020
Finding a good time for burndown herbicide applications has been a little tricky this spring, given the below-normal temperatures the first half of April and intermittent snow and rain, all of which can decrease herbicide efficacy. Checking the forecast can help identify an optimal window for application.
