Abstract

The present invention discloses one kind of pesticide for preventing and killing soil nematode and other pests and its preparation. Emamectin benzoate as main material is mixed with solvent, emulsifier and penetrant to form the pesticide oil cream. The pesticide oil cream is diluted and irradiated to roots or sprayed to soil so as to prevent and controlling meloidogyne hapla and other pests. It has simple use, low consumption, high pesticidal effect, fast degradation and no residue, and may be used in produce green food material.

Description

technical field [0001] The invention relates to a medicine for controlling soil pests and a preparation method, in particular to a medicine for controlling nematodes and other insects in soil and its preparation. Background technique [0002] In recent years, due to the limitation of economic interests in protected areas, it is difficult to plant a single crop year after year, and it is difficult to rotate stubble, resulting in nutrient imbalance in the soil. In addition, the excessive use of agrochemicals has led to a decrease in the types of soil beneficial microorganisms, which has caused nematodes and other nematodes in the soil. Insects are becoming more and more serious, and the yield and quality of their crops are seriously affected. Specifically, the longer the continuous cropping time, the greater the degree of harm. Therefore, in order to solve this practical problem, effectively eradicate or inhibit the growth of nematodes, etc., and provide crops with a soil tha...
