Embodiment 1

[0035] Add 18% penconazole, 2% Jinggangmycin A, 12% alkylphenol polyoxyethylene phosphate, 8% lignosulfonate and 60% deionized water into the sand mill cylinder respectively by weight percentage, stir After uniformity, pre-disperse with a high-shear machine, then transfer to a sand mill for sand grinding, add sanding medium zirconia beads, and start sanding, so that 96% of the particle size is below 3 μm; stop sanding after 7 hours, and filter , to remove the zirconia beads, that is, to prepare a bactericidal composition suspension containing penconazole and Jinggangmycin A.

Embodiment 2

[0037] 6% penconazole, 14% Jinggangmycin A, 9% alkylphenol polyoxyethylene phosphate, 6% fatty alcohol polyoxyethylene ether, and 65% white carbon black were prepared by premixing, Coarse crushing, re-mixing, and crushing with a jet mill. The crushed material is then added to the conical mixer. The mixed material with a fineness of 99% can pass through a 325-mesh standard sieve to obtain penconazole and Wettable powder of the fungicidal composition of Jinggangmycin A.

Embodiment 3

[0039] Add 16% penconazole, 4% Jinggangmycin A, 12% alkylphenol polyoxyethylene phosphate, 8% fatty alcohol polyoxyethylene ether and 60% deionized water into the sand mill cylinder respectively , after stirring evenly, pre-disperse with a high-shear machine, then transfer to a sand mill for sanding, add sanding medium zirconia beads, and start sanding so that 96% of the particle size is below 3 μm; stop sanding after 7 hours , filtered, and the zirconia beads were removed to obtain a bactericidal composition suspension containing penconazole and Jinggangmycin A.

Abstract

The invention discloses a bactericidal composition containing penconazole and validamycin A and a preparation method thereof, wherein penconazole and validamycin A are used as main components and then assisted with deionized water and an auxiliary agent to form a suspending agent, or form a wettable powder together with the auxiliary agent and a carrier. The penconazole and the validamycin A are compounded, and a higher synergistic action can be generated, thereby the disease control range is widened, the generation of drug resistance is delayed, the drug effect is markedly improved, the burden on peasants is lightened, and agricultural safe production and ecological environments are also ensured. The bactericidal composition is applied to the field of agricultural plant chemical protection and has excellent and highly efficient protecting and treating actions for the pathogen harms of fruit trees, vegetables, wheat, rice and the like.

Description

technical field [0001] The invention relates to a bactericidal composition containing penconazole and Jinggangmycin A and a preparation method thereof. Background technique [0002] Penconazole: chemical name: 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-methyl]-1-hydrogen-1, 2,4-triazole, the original drug is white crystal, a systemic triazole fungicide with protective, therapeutic and eradicating effects, is an inhibitor of sterol demethylation, an important component of destroying and preventing the cell membrane of germs The biosynthesis of the component ergosterol leads to the inability of the cell membrane to form and the death of the bacteria. Due to its good systemic properties, it can be quickly absorbed by crop roots, stems, leaves and other tissues, and conducted internally; the results of indoor activity testing and field efficacy tests show that it has a good effect on grape white rot. Control effect. However, the dosage and cost of a single dose are re...
