Metazachlor is widely used as a selective pre-emergence herbicide in agriculture, particularly for controlling annual grasses and certain broadleaf weeds in crops such as cereals, oilseed rape, and soybeans. It is effective in managing problematic weeds like blackgrass, ryegrass, and chickweed, helping to improve crop yield and field maintenance. Due to its soil activity, metazachlor is typically applied before weed seeds germinate, forming a protective herbicidal barrier in the top layer of soil. It is often favored in integrated weed management programs where resistance to other herbicides has developed. The solution formulation allows for easy tank mixing with other agrochemicals and ensures uniform application through standard spray equipment.
