Problems solved by technology

[0002] Melon and fruit crops are susceptible to various harmful bacteria during the growth process, such as cucumbers, watermelons, grapes, fruit trees, wax gourds, and tomatoes. Common diseases include anthracnose, powdery mildew, black spot, and leaf spot. The control will lead to the reduction or extinction of crop production due to diseases. There are many types of drugs for disease prevention and sterilization on the market. In addition to plant drugs, mineral drugs can be roughly divided into two types: alkaline drugs and acid drugs. There is a common defect in all of them. The residue of the drug has certain toxicity, and the melon and fruit cannot be used in the mature stage. Because the residue of the drug is harmful, the dosage should be strictly controlled or the concentration of the drug should be reduced, which will affect the sterilization effect.

Embodiment Construction

[0006] The raw material of the present invention is composed of quicklime, copper sulfate (bile alum), and plant ash. When used for prevention and treatment, its preparation method is: first, 2 kilograms of quicklime are pulverized, and 3 kilograms of cold water are added. Dissolve in water to form a paste for later use, add 0.9 kg of copper sulfate (bile alum) into 1 kg of cold water, stir and dissolve for later use, mix paste quicklime with dissolved copper sulfate, add 73 kg of water and stir evenly, then add 0.1 kg of plant ash Stir until it becomes liquid. When it is used in the onset period, its preparation method is the same, and the addition of quicklime is increased to 4-6 kg, and the amount of copper sulfate is increased to 1.8-2.6 kg. The invention is suitable for melon and fruit crops, and the stock solution is sprayed, and the effect of spraying under the leaves of plants is the best when used.
