Problems solved by technology

[0004] Both penconazole and ningnanmycin have high bactericidal activity, but after long-term single use, they are likely to cause drug resistance of plant pathogens, resulting in problems such as increased dosage, reduced control effect, and shortened duration. The repeated use of pesticides causes the degradation rate of pesticides in the soil to decrease, which is not conducive to the sustainable development of the environment

Embodiment 1

[0043] Penconazole and Ningnanmycin Suspension Concentrate

[0044] Penconazole 6g, Ningnanmycin 14g, Lignosulfonate 14.6g, Propylene Glycol 4.8g, Xanthan Gum 2g, Silicone Oil 0.8g, the balance is water to make up to 100g, other additives are mixed, through high-speed shearing Mix evenly, add penconazole and ningnamycin, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameter is all below 5 mm, and the powder containing penconazole and ningnamycin described in the present invention is obtained. Suspension formulations of fungicidal compositions.

Embodiment 2

[0046] Penconazole and Ningnanmycin Suspension Concentrate

[0047] Penconazole 8g, Ningnanmycin 12g, Lignosulfonate 5g, Propylene Glycol 2.4g, Xanthan Gum 1.1g, Silicone Oil 0.63g, make up the remaining water to 100g, mix other additives, and mix by high-speed shearing Evenly, add penconazole and ningnanmycin, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameter is all below 5mm, and the bactericidal powder containing penconazole and ningnanmycin described in the present invention is obtained. Suspension formulations of the compositions.

Embodiment 3

[0049] Penconazole and Hexaconazole Emulsion in Water

[0050] Penconazole 6g, Ningnanmycin 14g, castor oil polyoxyethylene ether 5, xylene 14.5g, propylene glycol 1g, silicone oil 0.2g, water to make up to 100g. Add the original drug penconazole and Ningnanmycin, solvent and emulsifier together to dissolve into a uniform oil phase; mix some water, antifreeze and other pesticide additives 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 for about half an hour to form an oil-in-water type water emulsion. That is, the aqueous emulsion of the fungicidal composition containing penconazole and ningnanmycin is prepared.

Abstract

The invention relates to a bactericidal composition in the pesticide compound field and the application thereof. The effective component of the bactericidal composition is the penconazole and ningnanmycin compound, the total weight percentage of the effective component in the bactericidal composition is 1-90 percent, preferably 8-70 percent, the residues are allowed and acceptable auxiliary ingredients in pesticides, and the known method can be adopted to prepare wettable powder, a suspending agent, a soluble liquor, missible oil, an aqueous emulsion and a moisture particulate agent. The bactericidal composition is mainly used for controlling fungous diseases to crops of vegetables, fruit trees, grain and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal composition compounded with penconazole and ningnanmycin and an application thereof. Background technique [0002] Penconazole, chemical name: 1-[2-(2,4-dichlorophenyl)pentyl]-1H-1,2,4-triazole, belongs to triazole fungicides and is a systemic fungicide Agent, has preventive and therapeutic effects, is an ergosterol demethylation inhibitor, and is effective against powdery mildew, rust fungus, sporophore, septoria, nigella on cereal crops, coffee, sugar beet fruit trees and grapes The bacteria of the genus Astrobacter are effective in preventing and controlling cereal and coffee rust, cereal, fruit tree and grape powdery mildew, peanut and beet leaf spot, apple scab and peanut white rot. If a single dose is used for a long time, the bacteria will easily develop resistance. The chemical structural formula is: . [0003] Ningnanmycin is a low-toxic a...
