Cultural Weed Management Practices

Cultural weed management practices¬†are things the producer can do that help the crop be more competitive against weeds. These are essential for decreasing weed issues in row crops and helping to optimize herbicide-based programs. Increasing the crop’s health and competitiveness allows it to¬†out-compete weeds and withstand existing weed pressure. Examples include maintaining optimal field nutrient availability, planting into weed-free soil, altering row spacing, and selecting varieties that compete well.

Additionally, cultural tactics also includes broader farm management practices that make the field less conducive to weed pressure. Examples include timely scouting for weeds, cover cropping, being aware of new weed problems in the area, and creating a stale seed bed.
