Embodiment 1

[0021] Example 1: 12% mandipropamid·oxaflucondone suspension concentrate.

[0022]

[0023]

[0024] The specific operation steps are as follows: first mix other additives, shear and mix evenly in a shearing machine, then add mandipropamid and oxaflucondone, and grind in a ball mill for 2-3 hours, so that the particle diameter is uniform 12% mandipropamid·oxaflucondone suspension concentrate can be prepared if the size is less than 5mm.

Embodiment 2

[0025] Example 2: 20% mandipropamid·oxaflucone aqueous emulsion.

[0026]

[0027] The specific operation steps are as follows: firstly mix mandipropamid, oxaflucondone, mesitylene and sorbitan fatty acid ester 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 reaching the phase inversion point, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain 20% bistynoyl Promethazil·oxafetocin emulsion in water.

Embodiment 3

[0028] Example 3: 18% mandipropamid·oxaflucondone microemulsion.

[0029]

[0030]

[0031] The specific operation steps are: first dissolve mandipropamid and oxaflucondone completely with fatty acid methyl ester, then add other additives, mix evenly, finally add water, after fully stirring, 18% diacetylene can be obtained Amidoxazone microemulsion.

Abstract

The invention discloses a bactericidal composition containing mandipropamid and famoxadone. The effective components are the mandipropamid and the famoxadone, the weight part ratio of the mandipropamid to the famoxadone is 1:10-10:1, and the total weight percentage of the mandipropamid and the famoxadone in the bactericidal composition is 1%-95%. According to the demands of practical application, the bactericidal composition can be prepared into one of water emulsion, micro-emulsion, a suspending agent, wettable powder and water dispersible granules and has the obvious synergistic effect on anthrachose of grape, potato late blight and other diseases, the using dosage of a pesticide is reduced, the pesticide cost is reduced, the service life of the pesticide is prolonged, and the adverse impact of the pesticide on the ecological environment is reduced.

Description

technical field [0001] The fungicidal composition of the present invention uses mandipropamid and oxafluconone as active ingredients, and is used for preventing and treating grape downy mildew and potato late blight. 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-efficien...
