Abstract

The present invention provides a composition, a preparation and applications of the composition and the preparation, and specifically relates to a bactericidal composition containing Florylcoxamid anddimethachlon, a preparation and applications of the bactericidal composition and the preparation, wherein a mass ratio of the effective component Florylcoxamid to the effectively component dimethachlon is 1-10:10-1, and the total content of Florylcoxamid and dimethachlon in the bactericidal composition or preparation is 1-90 wt%. According to the present invention, the compositions and the preparation have significant synergistic effect in the prevention and control of wheat powdery mildew, and are suitable for the prevention and control of the powdery mildew, the sheath blight, the rust, theSclerotinia sclerotiorum and the rice blast of cereal crops and the anthracnose of melons, fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition containing Florylpicoxamid and sclerotin, a preparation and an application thereof. Background technique [0002] Florylpicoxamid (trade name: Adavelt) is a pyridine amide fungicide developed by Dow AgroSciences. Its mechanism of action is to exert bactericidal activity by inhibiting the mitochondrial respiration at the binding site of fungal complex IIIQi ubiquinone (ie coenzyme Q) . For grains, grapes, fruit trees, nut trees, vegetables, etc., to prevent and control powdery mildew, anthracnose, scab, and pathogenic bacteria such as Septoria, Botrytis spp., Alternaria, and Sclerotinia disease caused. The chemical name of Florylpicoxamid is (1S)-2,2-bis(4-fluorophenyl)-1-methylethyl-N-[[3-(acetyloxy)-4-methoxy-2-pyridyl ]carbonyl]-L-alanine, the structural formula is: [0003] [0004] Sclerotin is a heterocyclic compound and belongs to imine ...
