Abstract

The invention provides a pyraclostrobin-difenoconazole microcapsule suspension agent and a preparation method thereof, wherein the pyraclostrobin-difenoconazole microcapsule suspension agent comprises, by mass, 1-20% of pyraclostrobin, 1-40% of difenoconazole, 6-10% of a microcapsule wall material, 15-20% of a microcapsule core solvent, 1-5% of an emulsifier, 0.1-1% of a thickener, 3-5% of a dispersant, 1-5% of an anti-freezing agent, 0.1-0.5% of a preservative, 1-3% of a pH value regulator, 0.1-1% of a curing agent, and the balance of water. According to the present invention, by successfullycompounding pyraclostrobin and difenoconazole, the synergistic effect is provided, the prevention and control effect is significantly improved, the pesticide consumption is reduced, and the environmental pollution and the pesticide residue are effectively reduced; and the pyraclostrobin-difenoconazole microcapsule suspension agent has advantages of good quick-acting property, long lasting time, environmental protection and good market potential.

Description

technical field [0001] The invention belongs to the field of fungicides, and in particular relates to a pyraclostrobin-difenoconazole microcapsule suspension and a preparation method thereof. Background technique [0002] As we all know, pests and diseases have great harm to the growth of crops, and chemical control plays a major role in plant pests and diseases. In recent years, the average annual use of pesticides in our country is too large, most of which are chemical pesticides, resulting in increasingly severe environmental pollution and food safety problems, endangering human health. It can be seen that the development of new pesticides with low toxicity, high efficiency and environmental friendliness is a real goal. The main outlet for the safety of agricultural products. [0003] Difenoconazole is a systemic fungicide with protective and therapeutic effects. It is relatively safe among the triazole fungicides, and has a wide bactericidal spectrum. Genus, Phoma, Se...
