Methylsulfonyl azole and bismerthiazol have high safety, and can be used for better guaranteeing safe production of agriculture and protecting the ecological environment.

The invention provides a method of spraying a microbial preparation for preventing and controlling plant diseases. The method comprises the following steps of step 1, performing root-irrigation treatment on crops to be prevented and treated with a bacteria solution of methylotrophy bacillus; step 2, performing foliage spraying on the crops to be prevented and treated with a bacteria solution of wuyiencin; and step 3, repeating steps from the step 1 to the step 2 for totally 3-4 times. The method has the beneficial effects that the two of the wuyiencin and the bacillus have good prevention andcontrol effects to the vegetable fungal diseases, have own considerations on the effect of preventing and controlling the diseases and perform implementation operation through combination by adoptingmanners of root irrigation with the methylotrophy bacillus and foliage spraying with the wuyiencin, so that the prevention and control effects to social crop diseases of the two of the wuyiencin and the bacillus are exerted to a greater extent, and a more effective matching application manner is provided to production of vegetable crops of protected areas.

The invention belongs to the technical field of pesticides and in particular relates to a traditional Chinese medicine type crop seed-dressing agent and a using method and an application thereof. The Chinese medicine type crop seed-dressing agent is mainly prepared from the following ingredients: 70-75% of traditional Chinese medicine powder mixture, 15-25% of sulfur powder, and 2-5% of kaolin or talcum powder, wherein the traditional Chinese medicine powder mixture is prepared from the following ingredients in part by weight: 20-25 parts of crushed garlic bulblet, 20-25 parts of crushed Houttuynia cordata, 12-20 parts of crushed purslane, 4-5 parts of crushed folium artemisiae argyi, 4-5 parts of crushed ginkgo leaf, and 4-5 parts of crushed sweet wormwood.
