[0070] Example 53, 54 Microcapsule Suspension-Suspension Concentrate

[0071] Mix kresastrobin, 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 micro capsule suspension. Dispersant, wetting agent, defoamer, thickener (can be added or not) are mixed evenly by high-speed shearing, and active ingredient B is added, and ball milled 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 containing dimoxystrobin and thiocarbamate, which contains an active component A and an active component B, wherein the active component A is selected from dimoxystrobin; the active component B is selected from any one of mancozeb, polyram, dithane and propineb; and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition disclosed by the invention has higher activity for multiple diseases on multiple crops, and has obvious synergistic action, thereby widening the bactericidal spectrum. The composition 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 on diseases of a fungicidal composition containing kresastrobin and thiocarbamate. technical background [0002] Dimoxystrobin molecular formula: C 19 h 22 N 2 o 3 , chemical name: (E)-2-(methoxyimino)-N-methyl-2[a-(2,5-dimethylphenoxy)-o-tolyl]acetamide, krasastrobin is Exoquinone inhibitors block electron conduction by acting on the cytochrome complex bc1 to inhibit mitochondrial respiration. It has protective, therapeutic and conductive properties, and inhibits spore germination and hyphae growth. [0003] Mancozeb (Mancozeb) chemical name: ethylene bisdithiocarbamoyl manganese and zinc complex salt. A protective fungicide with a broad bactericidal spectrum. It mainly inhibits the oxidation of pyruvate in bacteria. It is effective against various diseases such as anthracnose and early blight on fruit trees and vegetables. At the same time, it is often m...
