[0070] Example 74, 75 microcapsule suspension-suspension agent

[0071] 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 through high-speed shearing, then add imidazolidin, and ball mill in a ball mill for 2 to 3 hours, so that the particle size of all particles is below 5 μm. Prepare the suspending agent, then add the suspending agent to the aqueous phase solution of the microcapsule suspending agent, make up the balance with deionized water, and prepare the well-dispersed microcapsule suspension-suspension agent product of the composition of the present invention. See Table 7 for details.

Abstract

The invention discloses a bactericidal composition comprising fenamidone, the bactericidal composition comprises an active component A and an active component B, the active component A is selected from the fenamidone, the active component B is selected from any of the following compounds: cyazofamid, dimethomorph, fosetyl-aluminum, metalaxyl or a salt thereof and fluazinam, and the weight ratio of the active component A to the active component B is 1:80-60:1. The bactericidal composition of the invention has high activity against a variety of diseases of various crops, has an obvious synergistic effect and an expanded bactericidal spectrum, and has the characteristics of small drug use amount, rain drop erosion resistance and obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a bactericidal composition containing imidazolidin on crop diseases. technical background [0002] Myrmidones molecular formula: C 17 h 17 N 3 OS, chemical names: (S)-1-anilino-4-methyl-2-methylthio-4-phenylimidazolidin-5-one, imidazolidin and oxaflumedone and methoxyacrylate The mechanism of action of fungicides is similar, inhibiting liner respiration by blocking electron transfer at the hydrogenation enzyme Q-cytochrome C radon level, imidazole bacteria (s)-enantiomeric activity ratio (R)-enantiomer is much higher. [0003] Cyanamid (Cyanamid) chemical name: 4-chloro-2-cyano-5-p-methylphenyl-imidazole-1-N,N-dimethyl amide, molecular formula: C 13 h 13 ClN 4 o 2 S. It is a sulfimidazole fungicide, a super protective fungicide. The mechanism of action is to block the electron transfer of the mitochondrial cytochrome bc1 complex in the oomycete patho...
