Embodiment 1

[0042] Example 1: Ethyrimol Sulfonate Ningnanmycin Suspension Concentrate A

[0043] Mix 14.6 g of lignosulfonate, 4.8 g of propylene glycol, 2.4 g of xanthan gum, 0.84 g of silicone oil and 57.36 g of water; Mycin, grind the balls in a ball mill for 2 to 3 hours, so that the particle diameters are all below 5mm, and a suspension preparation A of the pyrithrimol sulfonate and Ningnanmycin fungicidal composition is prepared.

Embodiment 2

[0044] Example 2: Ethyrimolsulfonate Ningnanmycin Suspension Concentrate B

[0045] Mix 5.0 g of lignosulfonate, 2.4 g of propylene glycol, 1.1 g of xanthan gum, 0.63 g of silicone oil, and 70.87 g of water. After mixing uniformly by high-speed shearing, add 10.0 g of pyridilsulfonate and 10.0 g of Ningnan Mycin, grind the balls in a ball mill for 2 to 3 hours, so that the particle diameter is below 5 mm, and prepare the suspension preparation B of the bactericidal composition of pyrithrimol sulfonate and Ningnanmycin.

Embodiment 3

[0046] Example 3: Ethyrimol Sulfonate·Ningnanmycin Water Emulsion C

[0047] Mix 5.0 g pyridilsulfonate, 15.0 g ningnanmycin, 5.0 g castor oil polyoxyethylene ether, and 14.5 g xylene to dissolve into a uniform oil phase; mix 1.0 g propylene glycol, 0.2 g silicone oil, and 59.3 g water is mixed together to form a uniform water phase; while stirring at high speed in the reactor, add the oil phase to the water phase, slowly add water until the phase inversion point is reached, turn on the shearing machine for high-speed shearing, and add the remaining water, Shear about half an hour, form the water-in-water emulsion of oil-in-water type, make the water-emulsion C of pyrithrimol sulfonate and Ningnanmycin bactericidal composition.

Abstract

The invention relates to the technical field of pesticide combination, in particular to a sterilization composition containing bupirimate and ningnanmycin, and also relates to application of the sterilization composition. The sterilization composition comprises effective ingredients including bupirimate and ningnanmycin, wherein the weight part ratio of the two effective ingredients: bupirimate to ningnanmycin is 90:1-1:90, the sterilization composition is prepared into wettable powder, suspending agents, aqueous emulsions, water dispersible granules, missible oil and the like after auxiliary agents and excipient are added into the sterilization composition, and the sterilization composition is used for preventing and curing diseases and virus diseases caused by erysiphe, rust, mortierella, septoria, venturia and the like. The composition has good synergy effects in a certain range, the preventing effect is higher than that of single dosages, the pesticide effect is more durable, the special effects are realized on powdery mildews, rust diseases, apple scabs, gray molds, white rot and the like, the residue is lower, the composition can be easily decomposed after the lasting period, the environment is more friendly, and the production increase and the income increase of an agricultural region are favorably realized.

Description

[0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal composition containing pyridyl sulfonate and ningnanmectin, and also relates to the application of the bactericidal composition. Background technique [0002] Ethyrimolsulfonate, chemical name: 5-butyl-2-ethylamino-6-methylpyrimidin-4-yl dimethylaminosulfate, is an adenine nucleoside deaminase inhibitor, is a systemic Sexual fungicide, with protective and therapeutic effects, can be quickly absorbed by plant roots, stems, and leaves, and circulate to various parts of the plant body, so it is resistant to rain erosion. The effective period of spraying is 10-14 days, which can prevent and control powdery mildew on vegetables, flowers and fruit trees, and is safe for crops. However, the control spectrum of a single agent is narrow, and when used for a long time, the bacteria are likely to develop drug resistance. In addition, the cost of using this agent alone is relative...
