[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.

Abstract
The invention provides a fungicide and belongs to the technical field of pesticides. The active ingredients of the fungicide provided by the invention are benzovinfluconazole and pyrimethanil; the mass ratio of the benzovinfluconazole and pyrimethanil is 1: (1-20). Benzodiflufenazole acts on the protein complex II in the mitochondrial respiratory electron transport chain of pathogenic bacteria, causing tricarboxylic acid cycle disturbance, hindering its energy metabolism, and then inhibiting the growth of pathogenic bacteria, leading to their death, so as to achieve the purpose of disease prevention and control. The bactericidal mechanism of pyrimethanil is unique. It prevents the infection of bacteria by inhibiting the secretion of bacteria infection enzymes, and kills the bacteria. It has protective and therapeutic effects, as well as systemic and fumigation effects. The present invention adjusts the mass ratio of benzovinfluconazole and pyrimethanil to 1: (1-20), which has obvious synergistic effect, and at the same time reduces the resistance produced by a single drug, and the effects of synergistic and reduced application, Reduce the cost of pesticides for the prevention and control of crop diseases.
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...
