Sterilizing agent for preventing and curing diseases of vegetables and fruits and preparation method thereof

Abstract

The invention discloses a sterilizing agent for preventing and curing diseases of vegetables and fruits and a preparation method thereof. The sterilizing agent comprises the following ingredients in part by weight: 60 to 90 parts of peroxyacetic acid solution, 0.5 to 8 parts of surface active agent, 3 to 15 parts of inhibitor and 3 to 15 parts of promotion absorbent; the peroxyacetic acid solution is peroxyacetic acid with mass content of 18 to 23 percent sold in the market; the surface active agent is one or a mixture of alpha olefine sulfonate-9 (AOE-9), sucrose ester, sodium dodecyl sulfate and alkylphenol polyoxyethylene (OP-10); the inhibitor is one or a mixture of trimeric sodium phosphate, sodium silicate, hydroxyethylidene diphosphonic acid (HEDP), diethylene triamine pentamethylene phosphonic acid (DTPMP), diethylene triamine penta methylene phosphonic acid (DTPMPA) and amino trimethylene phosphonic acid (ATMPA); and the promotion absorbent is one or a mixture of citric acid, urea, potassium phosphate, potassium nitrate, amino acid and chitosan. The sterilizing agent prepared through the method is high efficient and safe and is free from causing drug resistance of viruses, bacteria and eumycete and free from polluting the environment.

Description

technical field [0001] The invention belongs to the technical field of sterilizing agents, and in particular relates to a sterilizing agent for preventing and treating vegetable and fruit diseases and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, my country's vegetable farmers and fruit farmers are developing well under the joint efforts of the government, scientific research departments, vegetable greenhouses and orchards. However, in recent years, the diseases of vegetables and fruits have become more serious, and many greenhouse vegetables and orchards have been lost. There are three main types of diseases, namely fungi, viruses, and bacteria. Among the diseases of vegetables, most of them belong to a variety of fungal diseases. For example, common ones are: gray mold, downy mildew, fusarium wilt, powdery mildew, sclerotinia, splinter blight, anthracnose, scab, black spot Leaf spot, Ye Lin disease, brown spo...

Problems solved by technology

[0003] At present, chemical pesticides are mainly used to prevent and control vegetable and fruit diseases, and the results are fast, especially when diseases occur. The state regulations on fruit diseases prohibit the use of organochlorine, organic mercury, 1059, carbofuran, monoclonal, phosphamide, methamidophos, fluoroacetate ammonium, etc.

Some vegetable and fruit farmers are still using it secretly. After people eat these vegetables and fruits, poisoning occurs and the harm is serious. Pesticide residues are very harmful to humans and animals, and long-term use has produced serious drug resistance.
