Pendimethalin is a selective pre-emergent herbicide commonly used to control annual grasses and certain broadleaf weeds in various crops such as corn, soybeans, cotton, and vegetables. It works by inhibiting seed germination and early root development in susceptible plants, effectively preventing weed growth before it emerges.
Pendimethalin is valued for its long residual activity, allowing for season-long weed control with a single application. However, it requires incorporation into the soil or activation by rainfall to be effective.
Proper application timing and stewardship practices are essential to maximize the efficacy of pendimethalin while minimizing the risk of crop injury and environmental contamination.
