Cyhalofoprin phytotoxicity treatment method

Cyhalofop-butyl is a safe herbicide, but it may also cause phytotoxicity during the selection period or when the application is not proper. The pesticide network Xiaobian briefly introduces the causes and treatment methods of cyhalofoprin.

Causes: Cyhalofop-butyl ester is safer for rice, but excessive application of pesticides during rice seedling stage can produce different symptoms of phytotoxicity.

Symptoms of phytotoxicity: Mild, moderate, and severe phytotoxicity are manifested by chlorotic brown spots on rice leaves. Mild phytotoxicity has no significant effect on rice growth and yield; moderate or high phytotoxicity inhibits rice growth and affects yield

Prevention and alleviation: When applying rice at the seedling stage, as long as the dosage is controlled, the phytotoxicity can be avoided. The phytotoxicity can be washed several times with water, and the high-quality foliar fertilizer plus the brassinolide plant growth regulator can be sprayed. .
