Selection of herbicides for specific crops (e.g., Pendimethalin for pre-emergence, 2,4-D for broadleaf control).

Integrated Pest Management (IPM) blends observation with restraint. Scout fields, identify the pest, set an economic threshold, and then act: biological controls, cultural tactics, resistant varieties, and targeted pesticides only when necessary. This minimizes costs and environmental footprints, keeping beneficial insects—predators and pollinators—alive and active.
