[0045]

Embodiment 13～24

[0046] Embodiment 13~24 water dispersible granules

[0047] Combine amfenpyram, active ingredient B, dispersant, wetting agent, disintegrating agent, filler, etc. through airflow pulverization to obtain the required particle size, and then add other additives such as binder (optional) to obtain Granulation materials. The water-dispersible granule product of the present invention can be obtained after quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying, see Table 2 for details.

Abstract

The invention discloses a fungicidal composition containing fenpyrazamine. The fungicidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from fenpyrazamine, the active ingredient B is selected from any one of the following compounds: mancozeb, propineb, metiram or zineb, and the weight ratio of the active ingredient A to the active ingredient B is (1: 80)-(50: 1). The composition disclosed by the invention has synergy against a variety of diseases in agricultural production, and can reduce the dosage of a pesticide, reduce the residual amount of the pesticide on crops, reduce environmental pollution, realize safety to people and animals and good environmental compatibility and enable the diseases to be less prone to producing drug resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a bactericidal composition containing fenpyrafen to crop diseases. Background technique [0002] Fenpyrazamine is a pyridine-based heterocyclic fungicide developed by Sumitomo Chemical Co., Ltd. Pathogen that inhibits the mechanism of action of the ergosterol biosynthetic pathway, showing inhibition of mycelial growth and spore germination and pollen tube growth. [0003] Mancozeb, propineb, mancozeb or mancozeb are all thiocarbamate fungicides, widely used in crop diseases. [0004] However, in the actual process of agricultural production, the most likely problem in disease control is the emergence of disease resistance. Combination of ingredients from different varieties is a common method for controlling resistant diseases. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is sy...
