Problems solved by technology

[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. Reduce the harvest rate of rice, the use of general insecticides will pollute the environment, there are residues, and the pests cannot be quickly eliminated, which not only increases the cost, but also affects the soil quality, and the acid-base problem is serious

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. [0004] The technica...
