Herbicide reduction in metribuzin-based weed control programs in corn

Abstract

The relative effectiveness of 13 metribuzin-based weed control programs in Zea mays was investigated in a 3-yr study. Reduction in herbicide rates was made by modifying some commonly used metribuzin-based herbicide programs for weed control in corn. Satisfactory weed control, corn yield and economic return were obtained under each herbicide treatment, suggesting that reduction in herbicide use to reduce environmental hazard and enhance the economic benefit is achievable. Among the various herbicide programs, banded herbicide application at reduced rates plus one cultivation was observed to be the most economic weed management practice. -from Authors
