Problems solved by technology

[0002] Crop diseases are one of the main factors causing crop yield reduction. Severe diseases can lead to substantial yield reduction, and many crops can no longer be replanted
Although the control of chemical pesticides has a certain effect, the pollution is serious, and with long-term application, many bacteria develop resistance, leading to an increase in the disease
At the same time, due to the large amount of pesticide application, the crops have phytotoxicity and poisoning, which seriously affects agricultural production. What is more serious is that there are a large number of toxic substances remaining in food, vegetables, fruits and all agricultural products. Animals are extremely harmful, and human and animal poisoning often occur, directly threatening human health

Abstract

The invention discloses a biopesticide with rich tea saponin, and relates to the technical field of biological pharmacy. The biopesticide is prepared from sasanqua seed meal, mugwort, cocklebur, sophora flavescens, rhizoma acori graminei and emulsifiers. The biopesticide has the advantages of being rich in the content of the tea saponin, flavonoids, organic acid, alkaloid and other antibacterial substance, high in activity and excellent in an antibacterial effect, and can prevent and control plant diseases with a remarkable effect, non-pollution and non-residue, so that in current all green pollution-free agricultural production, the biopesticide is extremely suitable for the prevention and treatment of pests and diseases of vegetables, melons, rice, fruits and dry crops.

Description

technical field [0001] The invention relates to the technical field of biopharmaceuticals, in particular to a biopesticide rich in tea saponin. Background technique [0002] Crop diseases are one of the main factors causing crop yield reduction. Severe diseases can lead to substantial yield reduction, and many crops can no longer be replanted. Although the control of chemical pesticides has a certain effect, the pollution is serious, and with long-term application, many bacteria develop resistance, leading to an increase in the disease. At the same time, due to the large amount of pesticide application, the crops have phytotoxicity and poisoning, which seriously affects agricultural production. What is more serious is that there are a large number of toxic substances remaining in food, vegetables, fruits and all agricultural products. Animals are extremely harmful, and human and animal poisoning often occur, directly threatening human health. In recent years, the use of bi...
