Volunteer corn is a competitive weed in the corn/soybean cropping system and if not controlled, may result in a yield penalty and contribute to survival of gray leaf spot and western corn rootworm. Consider these options for managing volunteer corn in soybean and corn.
Consider these three guidelines to ensure maximum weed control with Liberty in LibertyLink corn and soybean and view a time-lapse video demonstrating how quickly waterhemp regrows when treatment occurs after the optimal weed height of 4 inches or less.
View demonstrations of new technologies and herbicides for weed control in corn, soybeans, and sorghum and cover crops effects on soil health and pest management at the June 27 Weed Management and Cover Crops Field Day. It will be held at the South Central Ag Lab near Clay Center.
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.
With a delayed or compressed planting season, this week several growers asked whether they could immediately plant soybeans after a dicamba application. See how Extension Weed Scientist Amit Jhala replied.
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?
