Abstract

The invention relates to a method for preparing an azoxystrobin and cyproconazole compound suspending agent. The method comprises the following steps: (1) weighing the following raw drug components in parts by weight: 10-30 parts of an azoxystrobin raw drug, 5-15 parts of a cyproconazole raw drug, 3-5 parts of alkylphenol polyoxyethylene sodium sulfate, 2-4 parts of a dispersing agent and 2-4 parts of ethylene glycol; adding water to be 95%, and uniformly mixing, wherein the dispersing agent is a mixture of sodium lignin sulfonate and calcium lignosulphonate, and the mass ratio of the sodium lignin sulfonate to calcium lignosulphonate is (1.7-2.1):1; (2) grinding the mixed components in a grinding machine so as to obtain an initial suspending agent within 3-6 hours; and (3) mixing a thickening agent and water to be 5%, adding the mixture into the initial suspending agent, stirring at a high speed by a stirrer for 1-3 hours, thereby obtaining the suspending agent product. The method disclosed by the invention has the advantages that the compound suspending agent disclosed by the invention has excellent dispersion property, obvious drug effect, low dosage, lasting drug effect and excellent suspending property.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a suspension concentrate formulated with azoxystrobin and cyproconazole, and also to a preparation method for the suspension concentrate formulated with azoxystrobin and cyproconazole. Background technique [0002] At present, pests and diseases are very harmful to the growth of crops, and chemical control plays a major role in plant pests and diseases. In recent years, our country has used too much every year, most of which are chemical pesticides. As a result, environmental pollution and food safety problems have become increasingly serious, jeopardizing the survival of human beings. The development of new pesticides with low toxicity, high efficiency and environmental friendliness is the key to realizing the safety of agricultural products. The only way out. [0003] Azoxystrobin is a methoxyacrylate fungicidal pesticide with high efficiency and broad spectrum, which is ef...
