Abstract

The invention relates to a pollution-free pesticide microcapsule suspending preparation. The pollution-free pesticide microcapsule suspending preparation is prepared by the following raw materials by weight: 20-30 parts of pepper, 20-30 parts of ginkgo biloba sarcotesta, 20-30 parts of fructus cnidii, 10-30 parts of chinaberry bark, 15-25 parts of fructus quisqualis, etc. The pollution-free pesticide microcapsule suspending preparation has the characteristics of controlling farmland weeds and wide spectrum. Compared with a conventional preparation, the microcapsule suspending preparation has a good weed-eradicating effect, is safe to the environment, and difficultly produced pesticide resistance to the weeds, so that the microcapsule suspending preparation has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of pollution-free pesticides, and relates to a botanical herbicide and fungicide, in particular to a botanical herbicide with traditional Chinese medicine as the main active ingredient and a preparation method thereof. Background technique [0002] At present, although the development, development and practical application of domestic biopesticides have been improved to a certain extent, most of the agricultural pests are still using chemical pesticides and formulations that have long been outdated, such as emulsifiable concentrates, microemulsions, etc., but these formulations are harmful to the environment. There is a lot of pollution, and there is also a certain risk to the sprayers; although the microemulsion is less harmful to the environment, its drug effect is not ideal, so the development of new biological pesticides and pesticide formulations that are friendly to the environment and have a long durati...
