Environmentally friendly benzovindiflupyr nano powder and preparation method thereof

Abstract

The invention belongs to the technical field of pesticide, and especially relates to environmentally friendly benzovindiflupyr nano powder and a preparation method thereof. The environmentally friendly benzovindiflupyr nano powder comprises an active ingredient A. The active ingredient A is benzovindiflupyr. The environmentally friendly benzovindiflupyr nano powder also includes 10-30 wt% of a solvent, 10-25 wt% of a micromolecule auxiliary agent, less than 10 wt% of a macromolecule auxiliary agent and 40-50 wt% of dispersant water. After the formula is adopted, the benzovindiflupyr nano powder prepared by the preparation method of the invention is more efficient, more environmentally friendly and safer, changes a previous state that only high efficiency and low toxicity are preferred, andrequires that the environmental safety of medicine is taken as a primary condition.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to an environment-friendly benzovinfluconazole nanopowder and a preparation method thereof. Background technique [0002] Powdery mildew is a widespread worldwide disease. In production, chemical pesticides are mainly used to prevent and control powdery mildew. At present, it mainly relies on benzimidazoles, triazoles, and methoxyacrylate fungicides. However, long-term use of a single type of fungicide will lead to different degrees of disease resistance and reduce the control effect. [0003] Benzofenflubenazole is a pyrazole amide fungicide. By inhibiting the succinate dehydrogenase in the electron transport chain on the inner membrane of mitochondria, pathogenic fungi cannot generate energy through respiration, and then disrupt the growth of pathogenic bacteria. The cost of using alone is high and it is easy to develop resistance again, thereby reducing the service life of pe...

[0003] Benzofenflubenazole is a pyrazole amide fungicide. By inhibiting the succinate dehydrogenase in the electron transport chain on the inner membrane of mitochondria, pathogenic fungi cannot generate energy through respiration, and then disrupt the growth of pathogenic bacteria. The cost of using alone is high and it is easy to develop resistance, thereby reducing the service life of pesticide varieties

[0004] Penthiopyrad is a novel amide fungicide developed by Mitsui Chemicals, Japan. It not only has excellent activity against rust and sclerotinia, but also shows good bactericidal activity against gray mold, powdery mildew and apple scab. It is now recommended to control gray mold and powdery mildew that are resistant to other fungicides, but long-term use of penthiopyrad alone will also cause a great risk of resistance, which is not conducive to the effective control of diseases
