Quizalofop-ethyl is widely used as a selective herbicide in agriculture to control annual and perennial grassy weeds in broadleaf crops. It is particularly effective in crops such as soybeans, cotton, sunflowers, and sugar beets. The herbicide works by inhibiting the enzyme acetyl-CoA carboxylase, which is essential for fatty acid synthesis in grasses, leading to their death while leaving the broadleaf crops unharmed. Its application is typically done through foliar spraying, ensuring targeted action against unwanted grasses. Farmers value quizalofop-ethyl for its efficiency in weed management, which helps improve crop yield and quality. It is also favored for its relatively low environmental impact when used as directed.
