Weed Management

Early emerging weeds are strong competitors for soybean. Early season weed control is imperative to reduce yield loss from weed competition. 

Pre-seeding and Pre-emergent Herbicide Options for Pulses - April 2016

Weed control during the first to third trifoliate is the critical weed free period. After the soybeans form a canopy they are better able to compete with weeds. An integrated weed management system is recommended as an overall effective weed control system. Generally, weed management is accomplished by registered herbicide application, both pre-seed and in crop.

A wide range of commercial herbicides are registered for use in soybean,iIn particular, glyphosate is used on Roundup Ready varieties.
