Postemergence Weed Control in Soybeans

Timing of postemergence herbicide applications is more dependent on the weed growth stage than crop stage. However, small weeds are more readily controlled than large ones. Basagran, Blazer, Tackle, Scepter, combinations of these, Galaxy, Classic, and Cobra should be used when most susceptible weeds are no taller than 4 inches for best control. Nitrogen solutions (28-0-0 and 32-0-0 at 1 gallon per acre) increase Basagran, Blazer, Classic, and Galaxy activity but weed size "limitations remain. Taller weeds are defoliated but they often recover.

Herbicide Drift

Herbicide injury problems from drift and volatility occur each year. Farm crops as well as gardens, ornamentals and windbreaks are damaged. This not only applies to farm chemicals, but turfgrass herbicides as well.

Control Weeds on ACR Acres

Left unattended ACR acres can turn into a real weed problem next year. Take advantage of the opportunity to clean up a weed problem, don't create a problem for next year.

Weed Tour Reminder

The Nebraska Weed Tour is scheduled for Sidney on June 20 and Scottsbluff and North Platte on June 21. The Tour continues at Clay Center and Lincoln on June 22 and concludes on June 23.
