Embodiment 1

[0021] Example 1: 12% penthiopyrad·fludioxonil suspension concentrate.

[0022]

[0023] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add penthiopyrad and fludioxonil, grind in a ball mill for 2-3 hours, so that the particle diameter is below 5mm , to prepare 12% Penthiopyrad · Fludioxonil suspension concentrate.

Embodiment 2

[0024] Example 2: 22% penthiopyrad·fludioxonil emulsion in water.

[0025]

[0026] The specific operation steps are as follows: firstly, penthiopyrad, fludioxonil, mesitylene and sorbitan fatty acid ester are mixed together to dissolve into a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reaction kettle, slowly add water until the phase inversion point is reached, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain 22% pyrithiae bacteria Amine Fludioxonil Water Emulsion.

Embodiment 3

[0027] Example 3: 16% penthiopyrad·fludioxonil microemulsion.

[0028]

[0029] The specific operation steps are: first dissolve penthiopyrad and fludioxonil completely with fatty acid methyl ester, then add other additives, mix evenly, finally add water, after fully stirring, 16% penthiopyrad can be prepared · Fludioxonil microemulsion.

Abstract

The invention discloses a sterilization composition containing penthiopyrad and fludioxonil. According to the sterilization composition, penthiopyrad and fludioxonil are taken as the active ingredients, and weight ratio of penthiopyrad to fludioxonil ranges from 1:10 to 10:1; the total weight of penthiopyrad and fludioxonil accounts for 1 to 90% of the weight of the sterilization composition; the sterilization composition can be prepared into one agent selected from a water emulsion, a microemulsion, a suspending agent, a wettable powder, and a water dispersible granule, is used for preventing and treating cucurbites and tomato gray mould disease. Application amount of the sterilization composition is reduced, spraying times are reduced, application cost is reduced, and the sterilization composition is safe for crops.

Description

technical field [0001] The invention relates to a bactericidal composition containing penthiopyrad and fludioxonil, which is used as active ingredients for preventing and treating gray mold of melons and tomatoes. Background technique [0002] The problem of resistance to agricultural diseases is a global problem, and it has always been the focus of attention of agricultural science and technology workers. With the continuation of chemical disease control year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of bacteria is becoming more and more serious, and the types of resistant bacteria are increasing. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers, which is not conducive to the sustainable development of agriculture. Therefore, the research and development of high-efficiency,...
