Embodiment 1

[0012] Insecticide for controlling rice pests, the ingredients and parts by weight are: 25 parts of cypermethrin, 15 parts of tripterygium alkaloid, 10 parts of pyrethrum, 0.06 part of pentaerythritol stearate, 0.1 part of ethyl m-aminobenzoate methanesulfonate , 5 parts of emulsifier, 0.1 part of thickener, 0.2 part of synergist, 30 parts of water. The emulsifier is active polypeptide; the thickener is one or more mixtures of aluminum magnesium silicate, xanthan gum, hydroxymethyl cellulose and polyacrylic acid; Dialkanol and glyceryl glucoside. The dispersibility of the active ingredients of the insecticide in water is small, and the addition of the active polypeptide of the emulsifier improves the dispersibility of the active ingredients of the insecticide and increases the quality of the insecticide, and the active polypeptide has a certain inductive odor, which increases the The ingestion of insecticides by pests greatly improves the effect of insecticides. Pentaerythri...

Abstract

The invention discloses an insecticide for preventing and controlling rice insect pests and a preparation method thereof. The insecticide is prepared from the following components in parts by weight: 20-30 parts of cypermethrin, 10-15 parts of tripterygium wilfordii alkaloids, 8-12 parts of pyrethrum, 5-10 parts of active polypeptide, 0.05-0.08 part of pentaerythritol stearate, 0.1-0.2 part of tricaine methanesulfonate, 2-8 parts of an emulsifier, 0.1-0.5 part of a thickening agent, 5-10 parts of a co-solvent, 0.1-0.5 part of a synergist and 20-30 parts of water. The insecticide has the beneficial effects that the effective ingredients have a synergistic effect, have prevention and control effects higher than that of a single preparation, and can be used for preventing and controlling multiple insect pests; the insecticide has quick-acting and long-acting functions for insect pests, and insect pests cannot generate drug resistance to the insecticide; and the effective ingredients coming from plant sources are widely available and reproducible, can be easily degraded in the natural environment without chemical residue, and do not pollute soil.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to an insecticide for preventing and controlling rice pests and a preparation method thereof. Background technique [0002] Rice is the main food crop in my country, and it is planted in a wide area in China, and it is planted in many places across the country. There are many kinds of rice diseases and insect pests, and more than 250 kinds of insect pests have been found so far. The more serious diseases and insect pests mainly include rice planthopper, rice stem borer, rice leaf roller, rice stalk fly, armyworm, sheath blight, rice Blight, blight, bacterial streak etc. Generally, it is necessary to control pests and diseases 3-4 times from rice sowing to rice harvesting, especially the late tillering and heading stages of rice are the key to the prevention and control of rice pests.
