Problems solved by technology

In order to enhance the rapid development of the tree peony industry, it is imminent to develop biopesticides that are harmless to human health and the ecological environment and are not likely to cause pathogenic drug resistance. It has an obvious inhibitory effect on other fungal diseases such as peony powdery mildew, but the effect is not obvious. However, biological fertilizer and Bordeaux mixture play a role in inhibiting tree peony powdery mildew and promoting plant growth and prolonging plant growth through microbial nutrient competition and chemical action. Visible effect in flowering period

preparation example Construction

[0017] The preparation method of described biopesticide, comprises the following steps:

[0018] Step 1, the preparation of the biological fertilizer

[0019] Adding yeast to livestock manure, and the ratio of livestock manure to yeast mass is 500:1, stirring evenly, putting it into a fermentation room for fermentation, taking it out after 6-7 days to prepare a mixture, adding rapeseed cake to the mixture, and The mass ratio of the mixture to the rapeseed cake is 2:1, and after stirring evenly, it is aired to obtain a biological fertilizer;

[0020] Step 2, the preparation of the Bordeaux mixture

[0021] Put copper sulfate into water to dilute, and the mass ratio of copper sulfate to water is 1:80, after stirring evenly, make diluted copper sulfate, put quicklime into water, and the mass ratio of quicklime to water is 1:40, stir After uniformity, the lime milk is obtained, and the diluted copper sulfate is poured into the lime milk, and stirred while pouring to obtain the B...

Abstract

The invention belongs to the field of biotechnology, in particular to a biopesticide for controlling cercospora varrireolorWinter, and a preparation method for the biopesticide. Through the compounding of bacillus subtilis HS5B5 which has the antagonism to pathogenic fungi of cercospora varrireolorWinter, biological fertilizer and a Bordeaux mixture, growth and reproduction of cladosporium paeoniae can be effectively inhibited, so that the purpose of cercospora varrireolorWinter control can be realized; meanwhile, the Bordeaux mixture also has the inhibiting effect on other fungus diseases of peony, so that the control effect on the fungus diseases of peony is improved after the Bordeaux mixture is compounded with bacillus subtilis and the biological fertilizer. According to the biopesticide, as the biological fertilizer and the Bordeaux mixture are added into the bacillus subtilis HS5B5, the florescence is prolonged by 2-3 days averagely as compared with that of conventional planting. The biopesticide is adopted to control cercospora varrireolorWinter, and is safe to people and animals, free of environment pollution, efficient and broad in spectrum, and the possibility of drug resistance generation is low.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a biological pesticide for preventing and treating peony brown spot and a preparation method thereof. Background technique [0002] Peony is a famous ornamental flower in my country. During the process of growth and overwintering, it is easily infected by pathogenic microorganisms and causes disease. There are many types of peony diseases, and the damage is serious. Most of these diseases are fungal diseases, such as brown spot, gray mold, rust, powdery mildew and purple feather disease. They can cause partial necrosis of peony leaves or the death of whole leaves, harm the leaves, branches and rhizomes of peony, make peony fall leaves in advance, and affect its vegetative growth and ornamental value. Peony brown spot is one of the most serious diseases, which mainly damages the leaves, but can also infect stems and flowers. The disease mostly occurs before and after flo...
