Embodiment 13～24

[0047] Examples 13-24 Water dispersible granules

[0048] The benzamide, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are crushed together to obtain the required particle size, and then the binder (with or without addition) and other additives are added to obtain the system Granules. After the material is quantitatively fed into the fluidized bed granulating dryer, after granulation and drying, the water-dispersible granule product of the present invention can be prepared. See Tables 3 and 4 for details.

Abstract

The invention discloses a high-efficiency bactericidal composition containing zoxamide, which contains an active component A and an active component B, wherein the active component A is selected from zoxamide; the active component B is selected from any one of ethirimol or salts thereof, triflumizole, tetraconazole and prothioconazole; and the weight ratio of the active component A to the active component B is 1:60-80:1. The composition disclosed by the invention has higher activity for multiple diseases on multiple crops, has obvious synergistic action, widens the bactericidal spectrum, and has the characteristics of small dosage, rainfall erosion resistance and obvious synergistic action.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency bactericidal composition containing benzamide to crop diseases. technical background [0002] Benzoamide is a highly effective protective bactericide with a long lasting period and good resistance to rain washing. Its mechanism of action is unique among oomycete bactericides. It passes tubulin -Combination of subunits and rupture of the microtubule cytoskeleton to inhibit sclerotia. Benzoamide does not affect the movement, cyst formation or germination of zoospores. With the first cycle of sclerotia, the elongation of the bud tube is inhibited, thereby preventing the pathogen from penetrating the host plant. [0003] The ethoxylate is ethoxylate sulfonate. [0004] In the actual process of agricultural production, the most prone problem to prevent disease is the emergence of disease resistance. The compounding of ingredients of different varieties...
