I. Chemical Properties and Formulations

·Chemical Name: (±)-2 - methyl - 3 - phenoxybenzyl -(1R,S)- cis, trans - 3-(2 - chloro - 3,3,3 - trifluoropropenyl)-2,2 - dimethylcyclopropanecarboxylate

·Molecular Formula: C₂₃H₂₂ClF₃O₂

·Molecular Weight: 422.9 g/mol

·CAS Number：82657-04-3

·Physical and Chemical Properties:

 ·The pure product is a solid, and the technical drug is a yellow to light brown viscous liquid. It is insoluble in water and easily soluble in organic solvents (such as acetone and xylene).

 ·It has relatively strong stability, being stable under acidic conditions and easily decomposing under alkaline conditions.

·Common dosage forms:

 Emulsifiable concentrate (EC), Emulsion in water (EW), Suspension concentrate (SC), Wettable powder (WP), Granule (GR), etc.

II. Application Fields and Usage Scenarios

·Control of Agricultural Pests

·Crop Scope: Widely used in cotton, fruit trees (such as apples, citrus), vegetables (such as tomatoes, cucumbers), soybeans, corn, etc.

·Target Pests:

·Pests with Chewing Mouthparts: Cotton bollworm, Cabbage caterpillar, Fruit borer, Asian corn borer, etc.

·Pests with Piercing-sucking Mouthparts: Aphids, Leafhoppers, Whiteflies, Mites (such as citrus red mites), etc.

·Usage method:

·Foliar spray: Dilute and evenly spray on the leaves of crops to control foliar pests.

·Soil treatment: Apply granules by broadcasting or in furrows to control underground pests (such as grubs, cutworms).

·Example: Use bifenthrin EC in cotton fields to control cotton bollworms. The dosage per mu is about 30 - 50 ml, and spray after diluting with water.

III. Mechanism of Action

·Kill pests through contact and stomach poisoning, inhibit the sodium ion channels on the nerve cell membranes of insects, resulting in abnormal nerve signal transmission. Insects will experience convulsions, paralysis, and eventually death.

·It is effective against both adult pests and larvae, but has a relatively weak killing effect on eggs.
