Composite fungicide and preparation and application thereof

Abstract

The invention relates to a composite fungicide. The composite fungicide is characterized by being prepared from the following materials in parts by weight: 20 to 30 parts of sweet wormwood herb extract, 3 to 9 parts of naphthylacetic acid, 0.01 to 0.02 part of isopropyl palmitate, 0.001 to 0.01 part of polyglycerol-3 ricinoleat, 3 to 6 parts of cinnamyl aldehyde, 2 to 7 parts of bacillus subtilis, 3 to 7 parts of physcion, 1 to 3 parts of ethephon, 10 to 15 parts of surfactant, 10 to 15 parts of dichloromethane, 10 to 15 parts of achnatherum inebrians, 3 to 6 parts of humic acid, 8 to 15 parts of pimacol and 2 to 8 parts of herba geranii. The invention has the following advantages: a preparation process disclosed by the invention is simple, the process of preparation is environment-friendly and pollution-free, and the prepared fungicide is non-toxic, has a high fungicidal effect and a broad fungicidal spectrum, and can also promote the growth of crops.

Description

technical field [0001] The invention relates to the technical field of fungicide preparation, in particular to a composite fungicide and its preparation and application. Background technique [0002] Bactericides, also known as biocides, bactericides and algaecides, microbicides, etc., usually refer to chemical agents that can effectively control or kill microorganisms in water systems - bacteria, fungi and algae, mainly divided into agricultural fungicides and There are two kinds of industrial fungicides. According to the survey, there are more than 80,000 kinds of pathogenic microorganisms (fungi, strong bacteria, rickettsia, mycoplasma, viruses, algae, etc.) harmful to plants in the world. Plant diseases cause huge losses to agriculture. As a result, the average annual output of crops in the world is reduced by about 500Mt. In history, there have been many times in history that severe famines have been caused by the prevalence of certain plant diseases, and even a large n...

[0002] Bactericides, also known as biocides, bactericides and algicides, microbicides, etc., usually refer to chemical agents that can effectively control or kill microorganisms in water systems—bacteria, fungi, and algae. They are mainly divided into agricultural fungicides and There are two kinds of industrial fungicides. According to the survey, there are more than 80,000 kinds of pathogenic microorganisms (fungi, strong bacteria, rickettsia, mycoplasma, viruses, algae, etc.) harmful to plants in the world. Plant diseases cause huge losses to agriculture. As a result, the average annual output of crops in the world is reduced by about 500Mt. In history, there have been many times in history that severe famines have been caused by the prevalence of certain plant diseases, and even a large number of people have starved to death. The use of fungicides is an economical and effective way to prevent and control plant diseases. The existing fungicides are an economical and effective method for preventing and controlling plant diseases. Although the existing fungicides can kill the pests and diseases to a certain extent, they will damage the wheat while sterilizing and affect its yield. In addition, The sprayed fungicide residues are harmful to the environment and soil, and the environmental protection performance is poor
