example 13

[0050] Example 13~24 water dispersible granules

[0051] Fluopyram, active ingredient B, dispersant, wetting agent, disintegrating agent, filler, etc. 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 can be obtained after quantitatively sending the material into the fluidized bed granulation dryer for granulation and drying, see Table 3 and 4 for details.

[0076] Mix active ingredient B, polymer capsule wall material, and solvent to dissolve into a uniform oil phase, and add the oil phase to the aqueous phase solution containing emulsifier and pH regulator under shearing conditions to make a well-dispersed microparticle capsule suspension. Dispersant, wetting agent, defoamer, thickener (can be added or not) are mixed evenly by high-speed shearing, then added fluopyram, and ball milled in a ball mill for 2-3 hours, so that the particle size of all particles is below 5 μm , to prepare a suspending agent, and then adding the suspending agent to the aqueous phase solution of the microcapsule suspending agent, and supplementing the balance with deionized water, so as to make a well-dispersed microcapsule suspension-suspension agent product of the composition of the present invention. See Table 10 for details.

Abstract

The present invention discloses a fluopicolide-containing sterilization composition, which comprises an active component A and an active component B, wherein the active component A is selected from fluopicolide, the active component B is any one compound selected from cyazofamid, phosethyl-Al, cymoxanil, iprovalicarb and captan, and a weight ratio of the active component A to the active component B is 1:80-60:1. The composition provides high activities for a plurality of plant diseases of a plurality of crops, and has characteristics of significant synergistic effect, bacterial killing spectrum expanding, low use amount, rainfall erosion resistance, and significant synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing fluopicolide on crop diseases. technical background [0002] Fluopicolide chemical name: 2,6-dichloro-N-[(3-chloro-5-trifluoromethyl-2-pyridyl)methyl]benzamide, molecular formula: C 14 h 8 C l3 f 3 N 2 O. Fluopyram is an amide broad-spectrum fungicide, which has high biological activity against oomycete fungal pathogens, and has protective and therapeutic effects. Fluopyram has strong permeability. It can penetrate from the upper surface of the blade to the bottom, and conduct from the blade base to the blade tip. After the treatment of young shoots, it can protect the leaves from the infection of pathogens. It can also be distributed from the root along the xylem of the plant to the whole plant, but it cannot be transmitted along the phloem. [0003] Cyazofamid molecular formula: C 13 h 13 ClN 4 o 2 S. The mec...
