Embodiment 1

[0021] Example 1: 20% penthiopyrad · medistrobin 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 medistrobin, grind in a ball mill for 2-3 hours, so that the particle diameter is 5mm As follows, 20% penthiopyrad·medistrobin suspension can be prepared.

Embodiment 2

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

[0025]

[0026] The specific operation steps are as follows: firstly, penthiopyrad, metrastrobin, methylnaphthalene, and sorbitan fatty acid ester are mixed together, and dissolved to form 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·Metrastrobin Water Emulsion.

Embodiment 3

[0027] Example 3: 24% penthiopyrad · medistrobin microemulsion.

[0028]

[0029] The specific operation steps are: first dissolve penthiopyrad and metrastrobin completely with methyl oleate, then add other additives, mix evenly, finally add water, after fully stirring, 24% penthiopyridine can be prepared Metrastrobin microemulsion.

Abstract

The invention discloses a bactericidal composition containing penthiopyrad and meptyldinocap. Active components of the bactericidal composition are penthiopyrad and meptyldinocap. Weight ratio of penthiopyrad to meptyldinocap is 1:10-10:1. Total weight of penthiopyrad and meptyldinocap in the composition is 1-70 wt%. The bactericidal composition can be made into any one dosage form selected from emulsion in water, microemulsion, suspending agent, wettable powder and water dispersible granule. The bactericidal composition is used for controlling powdery mildew of melons, grape and strawberry. According to the invention, dosage of pesticide is reduced, frequency of drug administration is minimized, and medication cost is decreased. The bactericidal composition of the invention is safe to crops.

Description

technical field [0001] The invention relates to a bactericidal composition containing penthiopyrad and metrastrobin, which is used as active ingredients for preventing and treating powdery mildew of melons, grapes and strawberries. 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 o...
