Description
Clodinafop-propargyl is a foliar-absorbed aryloxyphenoxypropionate herbicide which has the capacity to inhibit the lipid biosynthesizing enzyme, acetyl coenzyme-A-carboxylase.
Clodinafop-propargyl is a member of the Oxyphenoxy acid ester chemical class, which includes the active ingredients fluazifop-butyl, fenoxaprop-ethyl, diclofop methyl, quizalofop-ethyl and haloxyfop-methyl.
Chemical Properties
Pure Clodinafop-propargyl is colorless crystal, vapor pressure (25℃)3.19×10-3mPa, Solubility (25℃): water 4.0mg/L, ethyl alcohol 97 mg/L, acetone 880 mg/L, methyl benzene 690mg/L, n-hexane 0.0086 mg/L. Distribution coefficient (octane/water): KOWlogP=3.9(25℃). Clodinafop-propargyl can inhibit the synthesis of ester-like biology. It can be used to control amur foxtail, oat grass, avena sterilis, green bristlegrass and other weeds.
Uses
Herbicides for weed control in wheat.
Definition
ChEBI: A carboxylic ester resulting from the formal condensation of the carboxy group of clodinafop with the hydroxy group of prop-2-yn-1-ol. It is widely used as a herbicide for the control of annual grass weeds in cereal crops.
Mode of action
Clodinafop-propargyl is to inhibit the activity of acetyl-CoA carboxylase in plants. It is a systemic conductive herbicide, absorbed by the leaves and sheaths of plants, transmitted by phloem, and accumulated in meristems of plants. In this case, acetyl-CoA carboxylase is inhibited, and fatty acid synthesis is stopped. So cell growth and division cannot proceed normally, and lipid-containing structures such as membrane systems are destroyed, leading to plant death.
Toxicity evaluation
