Clodinafop-Propargyl Mode of Action

Clodinafop-propargyl is an herbicide that works by inhibiting the enzyme acetyl-CoA carboxylase (ACCase), crucial for fatty acid synthesis in plants. It is absorbed by the leaves and stems of weeds, translocated through the phloem, and accumulates in the meristematic tissues. This inhibition disrupts cell growth and division, ultimately leading to the death of the plant due to the destruction of lipid-containing structures such as membranes.

Features of Clodinafop-Propargyl

Clodinafop-propargyl is an excellent herbicide for wheat, rye, and triticale fields, used post-emergence to control annual grassy weeds like wild oats, blackgrass, foxtail, and canary grass. It is highly safe for wheat and can be applied regardless of the wheat’s growth stage, from the two-leaf-one-heart stage to before jointing. The herbicide is effective even at low temperatures, which slows down weed control speed but does not compromise efficacy. Compared to older herbicides like fenoxaprop-p-ethyl, clodinafop-propargyl shows superior performance, especially against resistant weeds. The recommended dosage should not exceed 9g per acre to avoid adverse effects on wheat seedlings.
