Fights Herbicide Resistance
Weeds are becoming more and more resistant to herbicides. Mississippi soybean farmers must manage them. Your soybeans are at stake.

The Mississippi Soybean Promotion Board and the Take Action initiative are here to help every step of the way.

Can germinate 10 months out of the year and be a challenge to control.
Vining/climbing nature makes them difficult to control.
Resistance to glyphosate and both ALS and PPO-inhibiting herbicides.
Resistance to glyphosate in Mississippi.
Seeds can contaminate harvested seed.
Late season escapes can contribute to the weed soil seed bank.
Emerges from April through July, difficult to manage.
Becomes increasingly difficult to control because of profuse vegetative growth and a dense root system.
Tillage and glyphosate only offer marginal disruption and control.
