Bactericide mixture formula for improving pyraclostrobin control efficiency and preparation method

Abstract

The invention discloses a bactericide mixture formula for improving pyraclostrobin control efficiency and a preparation method, which relate to the application field of agricultural bactericide. The agricultural bactericide mixture comprises two active ingredients: pyraclostrobin and calcined lime; the mass part ratio is 1:10 to 1:100; a drug or a substance containing the two active ingredients is directly mixed before using, wherein the pyraclostrobin is an active compound or various preparations adopting the pyraclostrobin as a main active ingredient. The agricultural bactericide mixture is mainly used for smearing branches, smearing stems or whitening a tree body in winter and spring, but also can be used for spraying in the rainy season, and replaces a bordeaux mixture or a Bordeaux pulp to prevent and cure fruit tree and forest branch disease or prevent and cure leaf disease during the rainy season. The invented agricultural bactericide mixture overcomes the defects that the bordeaux mixture has no systemic and therapeutic effect, is complicated in preparation method, can cause environment pollution after heavy use, and the like, a rainwater washing out resistence ability of the pyraclostrobin is improved, the lasting period of the drug is prolonged, and a new idea is provided for developing and utilizing the bactericide.

Description

technical field [0001] The invention belongs to the application field of agricultural fungicides, and relates to a formula and a preparation method of a fungicide mixture containing pyraclostrobin and quicklime. Background technique [0002] Pyraclostrobin is a methoxyacrylate fungicide, which has protective and systemic therapeutic effects. It has a wide bactericidal spectrum and has good control effects on various crop diseases. In the prevention and control of fruit tree diseases, pyraclostrobin has a good control effect on various diseases such as anthracnose leaf blight, anthracnose, rot, branch and fruit ring spot; and it has broad-spectrum, high efficiency and safety. , low toxicity and other advantages, it is an ideal agent for the prevention and treatment of fruit tree diseases. However, pyraclostrobin has poor resistance to rain erosion, is easily decomposed by sunlight (ultraviolet decomposition), and has a relatively short duration of effect. Under normal condit...

AI Technical Summary

Problems solved by technology

[0006] In view of the defects of pyraclostrobin and Bordeaux mixture, the purpose of the present invention is to provide a set of formula and preparation method of pyraclostrobin and quicklime agricultural fungicide mixture, so as to overcome the systemic therapeutic effect and preparation method of Bordeaux mixture cumbersome, and environmental pollution caused by a large amount of use; enhance the resistance to rain erosion of pyraclostrobin, prolong the duration of pyraclostrobin; to replace Bordeaux mixture or Bordeaux pulp to control fruit tree branch diseases or Preventing Leaf Diseases During the Rainy Season
