Abstract

The invention discloses a pesticide composition for preventing and treating rice sheath blight disease and a preparation method thereof, and relates to the technical field of pesticides. The pesticidecomposition is prepared from 80 to 90 parts of validamycin and 10 to 20 parts of a traditional Chinese medicine raw medicine, wherein the traditional Chinese medicine raw medicine is prepared from the following raw materials: 24 to 32 parts of Chinese honeylocust fruit, 24 to 32 parts of radix sanguisorbae, 15 to 22 parts of flos rhododendri mollis, 15 to 22 parts of sapindus mukorossi peel and 5to 12 parts of tourmaline raw stone. The preparation method comprises the following steps: mixing the Chinese honeylocust fruit, the radix sanguisorbae, the flos rhododendri mollis and the sapindus mukorossi peel, adding water and an alcohol solvent, and extracting to obtain dry fine powder; uniformly mixing with the pretreated tourmaline fine powder to obtain a traditional Chinese medicine raw material; and finally, uniformly mixing the traditional Chinese medicine raw material with the validamycin to obtain the pesticide composition. The pesticide composition disclosed by the invention caninduce rice to generate a specific resistance effect and has a remarkable effect of preventing and treating the rice sheath blight disease; the pesticide composition does not contain chemical pesticide, has low risk of harm to human bodies and natural organisms, and has the advantages of high efficiency, low toxicity, low residue, good fast-acting property, long lasting period, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition for preventing and treating rice sheath blight and a preparation method thereof. Background technique [0002] In the process of rice growth, some diseases will inevitably occur. If they are not controlled in time, they will cause serious losses to the yield. However, frequent use of the same chemical agent to prevent and control these diseases often leads to the development of drug resistance of these pathogens. In order to solve these problems, pesticides with different mechanisms of action are usually combined in proportion, which can not only effectively delay the emergence of drug resistance in pathogenic populations, but also have a synergistic and reducing effect on the control of rice diseases. [0003] Sheath blight is the first rice disease, which brings huge losses to rice production. At present, Jinggangmycin is mainly used to control rice ...
