Product description：

Clodinafac is a post-germination herbicide developed by a company. It is mainly used to control annual gramineous weeds such as wild oats, wheat nipples, ryegrass and setaria. The herbicide is a chiral fluorine-containing phenoxycarboxylic acid herbicide, which is relatively stable in acidic media and is hydrolyzed in alkaline media. Methalin is an acetal coenzyme carboxylase inhibitor, a systemic conductive herbicide, absorbed by the leaves and leaf sheaths of the plant body, conducted by the phloem, accumulated in the meristem of the plant body, and inhibits the acetal coenzyme carboxylase. Fatty acid synthesis is stopped, cell growth and division cannot proceed normally, lipid-containing structures such as membrane systems are destroyed, and finally plant death is caused. It takes a week from the absorption of clodinaf to weed death. In single application, small grain crops do not have enough drug resistance, and special crop safeners are required.

Usage：

Sagegrass, wild oats, unreal oats, brachial grass, crabgrass, barnyard grass, cricket grass, ryegrass, millet, wheatgrass, chickweed, common bluegrass, golden settergrass, bristlegrass, Stone grass and fake sorghum etc.
