Efficient vegetable slow-release low-residue fungicide/bactericide and preparation thereof

Abstract

The invention proposes an efficient vegetable slow-release low-residue fungicide / bactericide and preparation thereof. The efficient vegetable slow-release low-residue fungicide / bactericide is preparedfrom a component A, a component B and a component C in a mass ratio of (1.8-2.5):1:0.3, the component A is prepared from the following raw materials: limestone, expanded perlite, plant ash, sodium alginate, raw tung oil, ethyl cellulose, diethanolamine, cetyl-dimethyl ammonium bromide and a surfactant, the component B is prepared from the following raw materials: mint, cacumen biotae, Chinese scholar tree bark and chrysanthemum indicum, and the component C is a 10-15 wt% silicon dioxide aqueous solution. Through reasonable compounding and raw material selection, plant activity ingredients areused for carrying out vegetable insecticidal sterilization, safety and efficiency are achieved, the slow-release sustained effect and soil improvement effect are good, the comprehensive sterilizationbenefit is good, and the efficient vegetable slow-release low-residue fungicide / bactericide is worth of promoting.

Description

technical field [0001] The invention relates to the technical field of agricultural fungicides, in particular to a high-efficiency slow-release low-residue fungicide for vegetables and its preparation. Background technique [0002] In horticultural crops and dry farming production, crops will encounter a variety of fungi or bacteria infection and get various diseases, often due to a variety of pathogenic or saprophytic fungi in the soil (such as Pythium, Phytophthora, Fusarium , Botrytis, etc.) and bacteria (soft rot fungi, etc.), causing problems such as rotten seeds, rotten roots, and dead seedlings. [0003] Vegetables refer to one of the foods that can be cooked and cooked to become food. They can provide a variety of vitamins and minerals necessary for the human body. 90% of the vitamin C and 60% of the vitamin A necessary for the human body come from vegetables. In addition, there are a variety of phytochemicals in vegetables, which are recognized as effective compone...

Problems solved by technology

[0004] In the prior art, chemical fungicides or biological fungicides are used. The medicinal materials contain suspensions of active ingredients such as thiram and prochloraz, and these ingredients have a certain stimulating effect on the skin and mucous membranes of the human body. In addition, these fungicides are attached to the Vegetables, or infiltrate into the plants and remain, posing a certain threat to human life and health. At the same time, these fungicides are scattered into the soil or evaporated into the air, and will flow into the river after the action of rainwater, polluting the water body and the coast. aquatic organisms

This kind of fungicide is harmful and poisonous, and the residual part will cause certain poison to people and livestock, and can also cause other human diseases. In addition, it can also cause pollution to the environment and make the ecology out of balance.
