Abstract

The present invention relates to the active ingredient quinalphos (A: the common name in English is quinalphos, and the chemical name is O, O-diethyl-O-(quinoxalin-2-yl) phosphorothioate) and bis Formamidine (B: English common name is amitraz, chemical name is N′-(2,4-dimethylphenyl)-N-{[(2,4-dimethylphenyl)imino]methyl} -N'-methylmethyleneaminoamine) is a pesticide mixed composition formed with a surfactant and an organic solvent in a reasonable ratio. The pesticide mixed composition is suitable for controlling aphids on vegetables, fruit trees, flowers and other crops, and can also control mites.

Description

technical field [0001] The invention relates to a pesticide mixed composition which is used as a mixed preparation of quetiafos and amitraz as active ingredients for preventing and controlling aphids on cotton, fruit trees, flowers and other crops. Specifically, it is a pesticide mixed composition with good environmental compatibility, which is processed by combining the active ingredients of pesticides, quinathion and amitraz, after formula screening, adding appropriate amount of organic solvents, surfactants and other components. Background technique [0002] China is a big country in the production and use of pesticides. About 1 million tons of pesticide preparations are used every year, and the area of ​​pest control and pest control exceeds 5 billion mu. In the control of pests, the use of highly toxic pesticides accounts for about 30% of the total use, and the use of four highly toxic varieties, methamidophos, methyl parathion, parathion and monocrotophos, accounts for...
