Abstract

An agricultural insecticide emulsion contains one of cypermethrin, efficient cypermethrin and efficient cyhalothrin, trichlorfon, emulsifier, assistant and solvent. Its advantages are broad spectrum, high effect, high stability, low poison, and low cost.

Description

technical field [0001] The invention relates to a chemical pesticide, in particular to an agricultural insecticidal emulsion for controlling crop pests. Background technique [0002] Due to the requirements of human health and environmental protection, pesticides with high toxicity and long residual time have been eliminated, and pyrethroid agricultural insecticides have emerged due to their low toxicity, high efficiency, and broad spectrum. Crop costs are too high to be economically viable for farmers to afford. Contents of the invention [0003] The object of the present invention is to provide an agricultural insecticide with low toxicity, high efficiency, broad spectrum and low price. Show through inventor's test, pyrethroid pesticides such as cypermethrin (molecular formula C 22 h 19 Cl 2 NO 3 ), Beta-cypermethrin (molecular formula C 22 h 19 Cl 2 NO 3 ), Beta-cyfluthrin (molecular formula C 22 h 18 Cl 2 FNO 3 ) are low-toxic, efficient, quick-acting, bro...
