Embodiment 1

[0034] 6.7% cyproconazole, 33.3% Jinggangmycin A, 5% alkylphenol polyoxyethylene ether phosphate, 5% alkylaryl polyoxyethylene ether and 50% deionized water were added to the In the sanding cylinder, 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 98% of the particle size is below 3 μm; after 6 hours Stop sanding, filter, and remove the zirconia beads to obtain a bactericidal composition suspension containing cyproconazole and Jinggangmycin A.

Embodiment 2

[0036] 11.4% cyproconazole, 28.6% Jinggangmycin A, 9% sodium naphthalenesulfonate formaldehyde condensate sodium salt, 6% alkylaryl polyoxyethylene ether, 45% white carbon black were respectively prepared by weight Pre-mixing, coarse crushing, re-mixing, jet mill crushing, and 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 a ring-containing Wettable powder of the fungicidal composition of proconazole and Jinggangmycin A.

Embodiment 3

[0038] Add 26.7% cyproconazole, 13.3% Jinggangmycin A, 11% naphthalenesulfonate sodium formaldehyde condensate sodium salt, 4% sodium lauryl sulfate and 45% deionized water into the sand mill cylinder respectively , after stirring evenly, pre-disperse with a high-shear machine, and then transfer to a sand mill for sanding, add sanding medium zirconia beads, start sanding, so that 98% of the particle size is below 3 μm; stop sanding after 6 hours , filtered, and the zirconia beads were removed to obtain a bactericidal composition suspension containing cyproconazole and Jinggangmycin A.

Abstract

The invention provides a sterilizing composition containing cyproconazole and validamycin A and a preparation method thereof. Cyproconazole and validamycin A are used as main components, and deionized water and an auxiliary agent are assisted to form a suspending agent or the main components, the auxiliary agent and a carrier form wettable powder; and the compounding of the cyproconazole and the validamycin A can generate higher synergistic effect, expand the disease preventing and treating range, delay the generation of drug resistance, obviously improve the pesticide effect, lightens the burden on peasants and guarantees the safe production of agriculture and ecological environment. The invention is applied to the field of chemical protection of agricultural plants and has excellent andefficient protecting and treating effects on fruit trees, vegetables, wheat, rice, and the like with pathogenic bacterial damages.

Description

technical field [0001] The invention relates to a bactericidal composition containing cyproconazole and Jinggangmycin A and a preparation method thereof. Background technique [0002] Cyproconazole: chemical name: 2-(4-chlorophenyl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol. This product is a triazole fungicide, the original drug is a colorless crystal, and it is a sterol demethylation inhibitor. The genus, Corythosporum, Septoria, and Scabella have preventive and therapeutic effects. It is a high-efficiency fungicide used for seed treatment or surface spraying of important economic crops, but the single dose and cost are relatively high, and long-term use will cause plants to develop resistance. [0003] Jinggangmycin A: chemical name: N-[(1S)-(1,4,6 / 5)-3-hydroxymethyl-4,5,6-trihydroxy-2-cyclohexenyl][O -β-D-glucopyranosyl-(1→3)]-(1S)-(1,2,4, / 3,5)-2,3,4-trihydroxy-5-hydroxymethylcyclohexyl amine. The pure product is a white powder, which is an agricultural anti...
