Abstract

The invention belongs to the field of pesticides, and particularly relates to a seed treatment agent for preventing and treating spodoptera frugiperda and a preparation method thereof. The seed treatment agent is mainly used for preventing and treating spodoptera frugiperda on corn or wheat. The seed treatment agent is composed of an active component chlorantraniliprole, a filler and auxiliaries. The preparation method of the seed treatment agent is simple in process and convenient in operation; the prevention and treatment effect of the seed treatment agent is obvious, and pesticide use frequency and pesticide use cost can be obviously reduced; and a solution is provided for prevention and treatment of grassland spodoptera frugiperda with serious generation overlapping.

Description

technical field [0001] The invention relates to a seed treatment agent in the field of pesticides, in particular to a chlorantraniliprole seed treatment agent for controlling Spodoptera frugiperda and a preparation method thereof. Background technique [0002] Spodoptera frugiperda (J.E.Smith) (commonly known as Fall Armyworm), Lepidoptera Noctuidae, is native to tropical and subtropical regions of America. It is one of the major migratory pests of the World Food and Agriculture Organization's global early warning. Spodoptera frugiperda invaded my country in 2019, causing serious damage to corn in Southwest China, South China, Jiangnan, the middle and lower reaches of the Yangtze River, Huanghuai, Northwest China and North China, posing a direct threat to my country's grain production. The currently reported methods for preventing and controlling Spodoptera frugiperda mainly include the use of emamectin benzoate, chlorantraniliprole, tetrachlorantraniliprole, phoxim, indoxa...
