Problems solved by technology
[0003] For a long time, pepper powdery mildew has been mainly controlled by chemical agents, such as fenxining, carbendazim, sulfur gel suspension, etc., which lead to the development of drug resistance of the disease, and at the same time threaten the safety of humans and animals, resulting in the increase of pesticide residues, a large number of natural enemies being killed, and farmland microbiology. The ecological balance is destroyed and the environment is polluted, which does not meet the requirements of pollution-free vegetable production

The invention relates to a biological agent for preventing the powdery mildew in pepper and the preparation method and the application thereof. The invention belongs to the technology field of biological pesticides. The agent is composed of raw egg yolk 19.5g, edible oil 1L and water 15kg. The preparation method includes: (a) taking the raw egg yolk 19.5g out and rinsing with the clear water for further use; (b) blending the egg yolk by the juice extractor, adding the edible oil 1L and blending the mixed liquid until the liquid is milk white; (c) adding the agent prepared in the method to the water 15kg and fully stirring the agent evenly. The prevention and cure effect can be achieved at more than 65% by spraying the agent on the pepper with the powdery mildew for three times. The agent has low-cost material, easy manufacture technology, good prevention effect, non-toxicity, harmlessness, non-environment pollution and good application prospect.
Description
Technical field: [0001] The invention belongs to the technical field of biological pesticides, and in particular relates to a biological agent for preventing and treating pepper powdery mildew, a preparation method and application thereof. Background technique: [0002] Pepper powdery mildew is caused by Leveillula taurica (Lev.) Arn., which belongs to Ascomycetes, powdery mildew order; the amorphic form is powdery mildew of capsicum, which belongs to half-knowledge fungus, hyphospora. The disease is a disease of pepper in the middle and late stage, and it has the characteristics of rapid epidemic. Under the condition of suitable environmental conditions, it can become a big epidemic in a short period of time. It is one of the important diseases in pepper production. [0003] For a long time, pepper powdery mildew has been mainly controlled by chemical agents, such as fenxining, carbendazim, sulfur gel suspension, etc., which lead to the development of drug resistance of the...
