Problems solved by technology

Nematodes spread through soil or seeds, can damage the root system of plants, or invade the organs above the ground, affect the growth and development of crops, and indirectly spread diseases caused by other microorganisms, causing great economic losses
The use of pesticides to control nematodes is an effective method commonly used in modern agriculture, but there are too few pesticides with high efficiency to kill nematodes

Abstract

The invention discloses an emamectin benzoate and fosthiazate compounded emulsion in water and a preparation method thereof. The emamectin benzoate and fosthiazate compounded emulsion in water is prepared from, by weight, 0.1%-30% of emamectin benzoate, 0.1%-30% of fosthiazate, 0.1%-30% of a solvent, 0.1%-10% of a surfactant, 1%-5% of a stabilizing agent, 1%-5% of an anti-freezing agent and the balance water. By a reasonable processing process, the prepared emulsion in water has the advantages of quick action, long lasting period, high cost performance and long storage period.

Description

technical field [0001] The invention relates to an emulsion in water compounded with emamectin and thiazophosphine and a preparation method thereof, belonging to the field of agricultural chemistry. Background technique [0002] Nematodes belong to the nematodes phylum Nematodes. They are small in size and can be observed under a microscope. There are about 3,000 species of nematodes that are harmful to plants. Most of them live in the soil, and some are parasitic in plants. Nematodes spread through soil or seeds, can damage the root system of plants, or invade the organs of the aboveground parts, affect the growth and development of crops, and indirectly spread diseases caused by other microorganisms, causing great economic losses. The use of pesticides to control nematodes is an effective method commonly used in modern agriculture, but there are too few pesticides with high efficiency to kill nematodes. [0003] Emamectin benzoate is a low-toxic insecticide and acaricide ...
