Active Ingredient: Clethodim – 25.4%
Clethodim is a selective, systemic herbicide from the cyclohexanedione class, designed specifically for controlling grass weeds without harming broadleaf plants. It works by inhibiting the ACCase enzyme (Acetyl-CoA Carboxylase), which is essential for fatty acid synthesis in grasses. This targeted action makes it ideal for use in a wide range of environments where non-grass plants need to be preserved.
After application, Clethodim is absorbed by the foliage and translocated throughout the grassy weed, concentrating in the growing points. Initial symptoms include stunted growth and a noticeable yellowing (chlorosis) of young tissue. This is followed by tissue browning (necrosis) and eventual death of the plant. These results are typically observed within 7–14 days, depending on the grass species and environmental conditions.
