WebBifenthrin is poorly soluble in water and often remains in soil. Its residual half-life in soil is between 7 days and 8 months, depending on the soil type, with a low mobility in most soil types. Bifenthrin has the longest known residual time in soil of insecticides currently on the market. It is a white, waxy solid with a faint sweet smell. Webplex molecules; cypermethrin is no excep-tion. Because of its complexity, there are eight different ways that the atoms that make up the cypermethrin molecule can arrange themselves in three dimensions. These are called isomers. Cypermethrin is a mixture of all eight isomers.1 Over ninety percent of the cypermethrin manufactured worldwide is ...

Cypermethrin - Wikipedia
WebCypermethrin is a broad-spectrum insecticide. It has a low aqueous solubility and is volatile. Whilst its chemical properties suggest that it should not leach to groundwater it has been detected. It is considered a serious marine pollutant. It is moderately persistent is soils but is likely to degrade moderately fast in water systems under ... WebCypermethrin is lipophilic and highest residues were found in the fat, the liver and kidney. Metabolism was very similar in all species and involved cleavage of the ester bond to form phenoxybenzoic acid and a cyclopropanecarboxylic acid … Webcypermethrin Synthetic pyrethroid High Azadirachtin Botanical 1 Beta-cyfluthrin Synthetic pyrethroid High Bifenazate Carbazate Moderate Bifenthrin Synthetic pyrethroid X High Carbaryl N-methyl carbamate X High Carbofuran N-methyl carbamate X High Chlorethoxyfos Organophosphate X High foods that are base ph
