Abstract

The invention discloses a formula and process of coumaphos. Coumaphos is suitable for various melons, fruits and vegetables and mainly has good insecticidal effects on fly pests. Coumaphos is mainly used for controlling various leaf miners on various melons and fruits, solanaceous vegetables, beans and leaf vegetables, such as liriomyza sativae Blanchard, liriomyza huidobrensis Blanchard, Melanagromyza sojae (Zehntner) de Meijere, Liriomyza chinensis (Kato) and American serpentine leaf miners and for controlling root maggots (red-eye grass mosquitoes on leeks), and the like on leeks, scallions and garlic in present melon, fruit and vegetable production. A broad-spectrum, efficient and multifunctional insecticide for livestock is prepared by adopting the formula and the process.

Description

technical field [0001] The invention belongs to the technical field of pesticide manufacture, and in particular relates to a formula and process of muscarinic acid. Background technique [0002] Masphos is an insect growth regulator low-toxic insecticide with very strong selectivity and is mainly active against Diptera insects. Its mechanism of action is to distort the larvae and pupae of Diptera insects in shape, and the adult larvae are incomplete or inhibited. The drug has contact killing and stomach poisoning effects, and has strong systemic conductivity, and has a long duration of action, but the speed of action is slow. Myzaphos has no toxic and side effects to humans and animals, and is safe to the environment. Contents of the invention [0003] The present invention proposes a formula and process of phosphatine, and the chemical name of phosphos is O, O-diethyl-O-(3-chloro-4-methylcoumarin-7) phosphorothioate. The formula is to prepare 2-cyclopropylamino-4,6-di...
