[0070] Example 57, 58 Microcapsule Suspension-Suspension Concentrate

[0071] Mix tiiazil, 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 microcapsule suspension. Mix the dispersant, wetting agent, defoamer, and thickener uniformly through high-speed shearing, add active ingredient B, and mill in a ball mill for 2 to 3 hours to make the particle size of all particles below 5 μm to prepare a suspension, and then The suspending agent is added to the aqueous phase solution of the microcapsule suspending agent, and the balance is made up with deionized water to prepare a 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 tiadinil and thiocarbamate. The composition comprises an active component A and an active component B. The active component A is selected from tiadinil, and the active component B is any one selected from mancozeb, metiram, zineb, and propineb. A weight ratio of the active component A to the active component B is 1:80-60:1. The composition provided by the invention has high activity against various diseases on various crops, and has a significant synergetic effect and expanded bactericidal spectrum. The composition also has the advantages of small dose, rainwater scouring resistance, and significant synergetic effect.

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 thianil and thiocarbamate. technical background [0002] Tiadinil, molecular formula: C 11 h 10 ClN 3 OS, chemical name: 3'-chloro-4,4'-dimethyl-1,2,3-thiadiazole-5-carboxanilide, the drug has good systemic properties and can be absorbed through the roots, And quickly spread to other parts, suitable for water surface use, long-lasting effect, good control effect on leaf blast and ear rice blast. [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 mixed with systemic fungicides to delay the emergence of r...
