Abstract

The invention discloses a water dispersible granule composition containing fluxapyroxad, diethyl aminoethyl hexanoate and tebuconazole, and application of the water dispersible granule composition. The water dispersible granule composition comprises the following components in weight content: 1 to 50 percent of a component A and 1 to 50 percent of a component B. The component A comprises fluxapyroxad and diethyl aminoethyl hexanoate in the ratio of 5 to 1, and the component B comprises tebuconazole. The bactericidal composition adopts water dispersible granule as a formulation, and is high in disintegration speed, good in dispersing performance, high in suspension rate and used for mist spraying. The formula of the water dispersible granule composition improves the pesticide effect and bacteriocidal spectrum through the reasonable rational combination of fluxapyroxad, diethyl aminoethyl hexanoate and tebuconazole, has obvious synergistic effect, reduces the dosage, and promotes plants to be strong and lodging-resistant. The water dispersible granule can be applied to crops, such as cucumbers, bananas, strawberries, grapes, wheat, oilseed rapes and paddies, and has a good control effect on powdery mildew and downy mildew of cucumber, venturia inaequalis, leaf spot and sclerotinia sclerotiorum of banana, grey mould fruit rot of strawberry and powdery mildew of grape.

Description

technical field [0001] The present invention relates to a fungicidal active compound composition and its application, in particular to a water-dispersible granule composition containing flufenapyramide, diethyl ethyl hexanoate and tebuconazole for preventing and controlling crop diseases and promoting the healthy growth of crops and its application. Background technique [0002] Flufenapyramide: It belongs to the broad-spectrum fungicides of carboxamides. Its mode of action is to inhibit the succinate dehydrogenase in the complex II of the mitochondrial respiratory chain, thereby inhibiting the germination of the target fungi's spores, germ tubes and bacteria. filamentous growth. Used to control fungal diseases. [0003] Tebuconazole: It belongs to the triazole fungicides. The mechanism of action on bacteria is to inhibit the demethylation of ergosterol on the cell membrane, so that the bacteria cannot form cell membranes, thereby killing the bacteria. It is a high-efficie...
