Embodiment 1

[0038] 30% Benzene Flufenazole-Pyrimethanil Suspension Concentrate (1:1.5)

[0039] The mass fraction ratio of each raw material is as follows: benzovinfluconazole 12%, pyrimethanil 18%, natural sophorolipid 1%, phosphate ester PEAS-03 4%, non-ionic fluorosurfactant FC-204 DX-3071SF 3%, xanthan gum 0.1%, silica 1%, ethylene glycol 5%, water to make up to 100%. During operation, add all raw materials into the preparation kettle, then add thickener, make up the amount with water, shear at 3000r / min for 15min, sand mill at 1500r / min for 90min, stir and defoam, and then get 30% benzovinflufenazole-pyrimidine Mycamine suspension.

Embodiment 2

[0041] 25% Benzene Fluconazole-Pyrimethanil Suspension Concentrate (1:4)

[0042] The mass fraction ratio of each raw material is as follows: benzovinfluconazole 5%, pyrimethanil 20%, natural sophorolipid 1%, phosphate ester PEAS-03 4%, non-ionic fluorosurfactant FC-204 DX-3071SF 3%, xanthan gum 0.1%, silica 1%, ethylene glycol 5%, water to make up to 100%. During operation, add all raw materials into the preparation kettle, then add thickener, make up the amount with water, shear at 3000r / min for 15min, sand mill at 1500r / min for 90min, stir and defoam, and then get 25% benzovinflupyrazole-pyrimidine Mycamine suspension.

Embodiment 3

[0044] 20% Benzene Flufenazole-Pyrimethanil Suspension Concentrate (1:4)

[0045] The mass fraction ratio of each raw material is as follows: benzovinfluconazole 4%, pyrimethanil 16%, natural sophorolipid 1%, phosphate ester PEAS-03 4%, non-ionic fluorosurfactant FC-204 DX-3071SF 3%, xanthan gum 0.1%, silica 1%, ethylene glycol 5%, water to make up to 100%. During operation, add all raw materials into the preparation kettle, then add thickener, make up the amount with water, cut at 3000r / min for 15min, sand mill at 1500r / min for 90min, stir and defoam, and then get 20% benzovinflupyrazole-pyrimidine Mycamine suspension.

Abstract

The invention provides a bactericide, and belongs to the technical field of pesticides. The effective components of the bactericide provided by the invention are benzovindiflupyr and pyrimethanil, wherein the mass ratio of the benzovindiflupyr to the pyrimethanil is 1: (1-20). The benzovindiflupyr acts on a protein complex II on a mitochondrial respiration electron transfer chain of pathogenic bacteria, so that tricarboxylic acid circulation disturbance is caused, energy metabolism of the tricarboxylic acid is hindered, growth of the pathogenic bacteria is inhibited, death of the pathogenic bacteria is caused, and the purpose of preventing and treating diseases is achieved. The pyrimethanil has a unique bactericidal action mechanism, prevents pathogen infection and kills pathogens by inhibiting secretion of pathogen infection enzymes, has protection and treatment effects, and also has systemic and fumigating effects. According to the invention, the mass ratio of benzovindiflupyr to pyrimethanil is adjusted to 1: (1-20), so that the bactericide has an obvious synergistic effect, meanwhile, the resistance generated by use of a single agent is reduced, the effects of synergism and application reduction are achieved, and the pesticide cost for preventing and treating crop diseases is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide. Background technique [0002] Rust is a kind of plant disease caused by the parasitism of rust in fungi, which harms the leaves, stems and fruits of plants. Rusts generally only cause local infection, and the affected parts can produce small pustules or blisters, cups, and hairs of different colors due to the accumulation of spores, and some can also cause tumors, rough skin, and arbuscular branches on the branches. , curved branches and other symptoms, or cause fallen leaves, scorched shoots, poor growth, etc. In severe cases, the spores are densely piled into sheets, and the plants die quickly due to a large amount of water evaporation in the body. Rust is widely distributed and harmful, and it is more common in cereal crops, leguminous plants and pears. The rust of many crops is worldwide, and some have the characteristics of being prevalent in large regions...
