A kind of fungicide composition and its application

Abstract

The invention discloses a bactericide composition which comprises the following raw materials (in percentage by mass): 1-30% of methoxy-acrylic bactericide, 10-60% of plant oil, 0.1-0.5% of an antioxidant, 10-30% of a surfactant and the balance of VOC (Volatile Organic Compound) solvent. The invention provides the bactericide composition for compounding and dissolving methoxy-acrylic bactericide, not only can be generation of medicine resistance of methoxy-acrylic bactericide delayed, but also application of toxic solvents is avoided, the blending function of the components is sufficiently utilized, the synergism function is remarkable, the fungicidal efficiency is remarkably improved, and the bactericide composition is mainly used for preventing and treating diseases on grain crops, vegetables and fruit trees.

Description

technical field [0001] The invention relates to a fungicide composition and belongs to the field of agricultural medicament combinations. Background technique [0002] Methoxyacrylate (strobilurin) fungicides are derived from strobilurin A, a natural antibiotic with bactericidal activity. They are non-carcinogenic and mutagenic. Diseases caused by fungi such as fungi and oomycetes. Due to its unique mechanism of action, high environmental safety and ultra-high activity, it has broad development prospects. Its mechanism of action is relatively clear at present. The active group of this type of fungicide is methoxyacrylic acid (ester / amide), which mainly acts on the cytochrome bel complex in the mitochondrial respiratory chain of fungi, preventing electron transfer and thus inhibiting fungal growth. Such fungicides include azoxystrobin, kresoxim-methyl, enoxastrobin and the like. It has good activity against Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes, and can...

AI Technical Summary

Problems solved by technology

[0003] Moreover, the methoxyacrylate fungicides currently on the market, such as azoxystrobin, kresstrobin, and pyraclostrobin, have poor water solubility, and the solid preparations have large particles that are difficult to systemically absorb into the crops. Toluene, xylene and other toxic solvents are generally used to make liquid preparations. The use of such toxic chemical pesticides in large quantities will bring serious problems to agricultural production, food safety and environmental protection.
