Slow release gel ball with function of preventing plant disease and preparation method thereof

Abstract

The invention discloses a slow release gel ball with a function of preventing plant disease and a preparation method thereof and in particular relates to the agricultural field. The slow release gel ball comprises an outer supporting molding layer (1) with a bacteriostasis function, a release slow colloid layer (2) and a medicinal factor (4). The outer supporting molding layer (1) coats the outerside of the release slow colloid layer (2). The medicinal factor (4) is prepared from the following components in parts by weight: 20-30 parts of atiaris toxicaria latex, 15-25 parts of mlia azedarachethanol extract, 10-20 parts of aconite ethanol extract, 15-25 parts of znthoxylum piperitum petroleum ether extract and 10-25 parts of ginkgo nut ethanol extract. The release slow colloid layer (2)is selected from at least one of gelatin, pectin and a chitosan-perillaldehyde gel. By burying the slow release gel ball provided by the invention in soil of the root of a target plant, breeding of eggs or destroy of the root of the plant by pathogenic microorganisms can be prevented in a long term, so that the function of preventing plant disease is achieved finally.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a slow-release gel ball with the function of preventing and controlling plant diseases. Background technique [0002] In modern agricultural production, pesticides refer to chemical agents used in agriculture to prevent and control plant diseases and insect pests and regulate plant growth. Obviously, pesticides play an irreplaceable role in modern agricultural production. [0003] However, traditional pesticides are easily decomposed by light and washed away by rain. Once the pesticide is lost, it will not only affect the application effect of the plant, but also cause pollution to other soils. Therefore, how to improve the utilization rate of pesticides and reduce the pollution caused by the application of pesticides is an urgent problem for technicians to solve. Contents of the invention [0004] The invention provides a slow-release gel ball with the function of preventing and ...
