Pay attention to growth stage for spring herbicide decisions on wheat

Producers should pay close attention to the growth stage of their wheat before making spring herbicide applications. Some herbicides must be applied after tillering, several before jointing, and others can be applied through the boot stage. Weeds are most susceptible to herbicides when at early growth stages.

Residual herbicides for corn

Residual herbicides that kill weed seeds and/or seedlings as they germinate or emerge are important for herbicide applications at or before corn planting. These herbicides can control weeds for several weeks, which prevents yield loss due to early-season weed competition.
