Problems solved by technology

[0002] my country is rich in medicinal plant resources. The book "China's Soil Pesticides" published in 1959 recorded 220 kinds of plant pesticides, belonging to 86 families, with natural active substances that kill insects and sterilize bacteria. The water extract has a 90% inhibition rate on the germination of potato late blight spores, and the 15-fold boiled liquid of Artemisia annua has a 50-60% control effect on wheat leaf rust. These single plants are used as pesticide fungicides, not only the liquid used High concentration consumes Chinese herbal medicine resources, increases the cost of crop disease control, and the efficacy is not good enough
For this reason, in recent years, many enterprises have been involved in...

example 1

[0037] Choose 70 grams of rhubarb, 90 grams of pituitary bark, 110 grams of shegan and 90 grams of gallnut containing 70% natural gallic acid tannins, and grind them into fine powders with a particle size of not less than 60 meshes, put them into a reaction kettle after uniform mixing, and then Add 1000g of water, heat to 100°C, maintain the temperature for 40 minutes under stirring conditions, then cool to 50°C and maintain the temperature for 30 minutes, then cool down naturally to not lower than 5°C under the condition of full contact with air , put it aside for 12 hours, then filter to obtain a liquid medicine; then add 1000 grams of water to the medicine dregs, heat to 120°C, keep at this temperature for 50 minutes, and cool down to 40°C under the condition of full contact with air. After keeping at this temperature for 30 minutes, filter to obtain a secondary medicinal liquid; after fully mixing the primary medicinal liquid and the secondary medicinal liquid, leave it to ...

example 2

[0039] Choose 90 grams of rhubarb, 80 grams of pituitary bark, 130 grams of shegan and 100 grams of salt bran containing 70% natural gallic acid tannin, and the production method is the same as example 1 to obtain biological pesticides, which are used to prevent and treat plant fungal diseases.

example 3

[0041] Choose 60 grams of rhubarb, 50 grams of pituitary bark, 100 grams of shegan and 100 grams of myrobalan containing 70% natural gallic acid tannin, and the production method is the same as example 1 to obtain biological pesticides for preventing and treating plant fungal diseases.

Abstract

A biological pesticide for preventing and controlling plant fungus diseases and virus diseases is prepared by using rhubarb 60-140 weight portions, blackberrylily rhizome 100-140 weight portions, bark of himalayan coralbean 50-90 weight portions, and natural plant tannin 30-70 weight portions and through crushing into 40 mesh over fine powder, mixing, twice water boiling and mixing the boiled liquid. It has specific effect and high specificity on preventing and controlling plant fungus diseases and virus diseases.

Description

technical field [0001] The invention relates to a biopesticide for preventing and treating plant fungal diseases and viral diseases and a production method of the biopesticide. Background technique [0002] my country is rich in medicinal plant resources. The book "China's Soil Pesticides" published in 1959 recorded 220 kinds of plant pesticides, belonging to 86 families, with natural active substances that kill insects and sterilize bacteria. The water extract has a 90% inhibition rate on the germination of potato late blight spores, and the 15-fold boiled liquid of Artemisia annua has a 50-60% control effect on wheat leaf rust. These single plants are used as pesticide fungicides, not only the liquid used The high concentration consumes Chinese herbal medicine resources, increases the cost of preventing and controlling crop diseases, and the drug effect is not good enough. For this reason, in recent years, many enterprises have been involved in the further research and deve...
