The preparation method comprises the following steps of: uniformly mixing the active constituents and the liquid assistant in the formula, and making the mixture adsorbed on the carriers, mixing the mixture with other solid constituents, pulverizing the mixture by using an airflow pulverizer so that the grain size of the mixture reaches 98%, sieving the mixture by using a sieve of 45 mum, and then kneading and pelleting. Alternatively, the method comprises the following steps of: uniformly mixing the active constituents, the solvents and the liquid assistant in the formula, making the mixture uniformly adsorbed on solid constituents and carriers pulverized to the grain size of 98% so as to pass through sieving holes of 45 mum, and then kneading and pelleting. The emulsifiable granule solves the problems of short effect taking time and environmental pollution of the traditional etofenprox and pymetrozine insecticide.

The invention relates to a compound synergistic bactericidal composition for preventing and curing main diseases of tomatoes and pear trees, and an application of the composition. The active components of the pesticide composition comprises adepidyntm and an active component B, wherein the active component B comprises one selected from a group consisting of strobilurin fungicides, an ergosterol synthesis inhibitor, substituted aniline fungicides and bacillus subtilis BAB-1. The pesticide composition provided by the invention is applied in preventing and curing main diseases of tomatoes and pear trees such as grey mold, early blight, leaf mold, grey leaf spot, Venturia inaequalis, ring spot, black spot and the like, has a good fast-acting property and persistence, has a novel action mechanism, has many sites, can effectively delay the generation and development of drug resistance of pathogenic bacteria, and not only has protection effects against diseases, but also has good curing effects. The compound synergistic composition has less pesticide usage amount, and effectively reduces pollution on fruits and environment by drugs.

The invention discloses an isothiazolone-containing bactericidal composition and application thereof, and in particular relates to a bactericidal composition containing isothiazolone as a first active component and amino-oligosaccharin as a second active component, and application thereof.
