example 1～9

[0045] Example 1~9 wettable powder

[0046] Mix fluopyram, active ingredient B, dispersant, wetting agent, and filler, mix uniformly in a mixing tank, pulverize through a jet mill, and then mix uniformly to prepare the wettable powder product of the present invention. See Table 1 for details.

[0048]

example 10～18

[0049] Example 10~18 water dispersible granule

[0050] Fluopyram, active ingredient B, dispersant, wetting agent, disintegrant, and filler are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain the preparation grain materials. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying. See Table 2 for details.

Abstract

The invention discloses a bactericidal composition. The bactericidal composition comprises an active component A and an active component B, wherein the active component A is selected from fluopyram; the active component B is selected from any one of the following compounds: prochloraz or salt of the prochloraz, polyoxins and triflumizole; and the weight ratio of the active component A to the active component B is (1 to 80)-(60 to 1). The composition has the relatively high activity on a plurality of diseases of a plurality of crops, and has an obvious synergistic effect; the bacteriocidal spectrum is expanded; meanwhile, the bactericidal composition has the advantages of small chemical consumption, resistance to rainwash, and obvious synergism.

Description

[0001] This application is a divisional application. The original application is a patent application "a fungicidal composition" of Shaanxi Meibang Pesticide Co., Ltd. The application number of the original application is: 201210239628.8, and the original application date is 2012.07.11. technical field [0002] The invention belongs to the technical field of pesticides and relates to the application of a bactericidal composition on crop diseases. technical background [0003] Fluopyram (Fluopyram) chemical name: N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl)ethyl]-α,α,α-trifluoro-0-toluene Amide, molecular formula: C 16 h 11 CIF 6 N 2 O. It inhibits mitochondrial respiration by blocking electron transfer from succinate dehydrogenase in the respiratory chain. The purpose of controlling pathogenic bacteria is achieved by inhibiting several stages in the growth cycle of pathogenic bacteria. It is mainly used to prevent and control diseases caused by Ascomycetes on broad-lea...
