Special insecticide for rice and preparation method thereof

Abstract

The invention relates to a special insecticide for rice and a preparation method thereof. The raw materials comprise the following components in parts by weight: 2-5 parts of nicotine, 4-8 parts of pyrethrin, 2-4 parts of TBHQ, 5-12 parts of azadirachta indica, 20-30 parts of emamectin benzoate, 5-9 parts of cocoanut fatty acid diethanolamide, 2-5 parts of hot pepper, 3-10 parts of garlic, 2-5 parts of thiodiacrylate and 8-10 parts of deionized water. The insecticide provided by the invention is easily available in material, low in cost, free of influence on the environment, insecticidally super-efficient, nearly non-toxic, low in residue, pollution-free and green and environment-friendly, maintains normal production of rice, does not harm the quality of soil, keeps acid-base equilibrium, is strong in anti-oxidizing capacity, the service life is prolonged, and the insecticide is high in stability, good permeability and good in uniform effect.

Description

technical field

[0001] The invention relates to the field of insecticides, in particular to a special insecticide for rice and a preparation method thereof. Background technique

[0002] China is a large agricultural country. With the development of modernization, rice, as one of the main sources of food, has a very important position. However, rice cultivation is relatively cumbersome, and it is easy to cause insect damage during the growth process, affecting normal growth, or even stopping development. The harvest rate of rice is reduced, and the use of general insecticides pollutes the environment and has residues, and cannot quickly eliminate insect pests, which not only increases costs, but also affects soil quality, and the acid-base problem is serious. Contents of the invention

[0003] The purpose of the present invention is to provide a kind of special insecticide for rice and preparation method thereof in order to overcome above deficiency.
