Embodiment 1

[0020] A bactericidal aqueous emulsion containing tetramycin and azoxystrobin, the active ingredient of the bactericidal aqueous emulsion is a binary compound of tetramycin and azoxystrobin, 10 parts of tetramycin; 5 parts of azoxystrobin; dodecane 10 parts of calcium phenyl sulfonate and fatty acid polyoxyethylene ether; 10 parts of toluene; 5 parts of sodium citrate; 3 parts of ethylene glycol; 2 parts of silicone oil; 1 part of xanthan gum; water, the rest.

[0021] First, add tetramycin, azoxystrobin, solvent, and emulsifier together to dissolve into a uniform oil phase; mix part of water, antifreeze, defoamer, and thickener 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 shearer for high-speed shearing, and add the remaining water, shear for about half an hour to form oil-in-water Type emulsion in water can be made into the em...

Embodiment 2

[0022] Example 2: Toxicity test of different ratios of tetramycin and azoxystrobin.

[0023] 1.1 Test target

[0024] It was collected and isolated from potted cucumbers of the same type that had never been treated with tetramycin and azoxystrobin in Taizhou, Zhejiang Province. The cucumber variety for testing was Changchun Mici.

Abstract

The invention relates to the technical field of pesticide compounding and particularly relates to a tetramycin and azoxystrobin containing sterilizing aqueous emulsion and a preparation method thereof. According to the tetramycin and azoxystrobin containing sterilizing aqueous emulsion, effective ingredients of the sterilizing aqueous emulsion consist of tetramycin and azoxystrobin which are subjected to binary compounding; the sterilizing aqueous emulsion contains the following ingredients in parts by mass: 1-50 parts of tetramycin, 1-50 parts of azoxystrobin, 3-30 parts of emulsifying agent, 5-15 parts of solvent, 2-15 parts of stabilizing agent, 1-5 parts of anti-freezing agent, 0.1-8 parts of anti-foaming agent, 0.2-2 parts of thickening agent and the balance of water. The compounded sterilizing agent, which takes tetramycin and azoxystrobin as the effective ingredients, disclosed by the invention has an obvious synergistic effect, so that the generation of key drug resistance is retarded, the production cost and use cost are reduced, and thus, the compounded sterilizing agent can be applied to control on resistance diseases.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal aqueous emulsion containing tetramycin and azoxystrobin and a preparation method thereof. Background technique [0002] Tetramycin (Wuningmycin) is a fermentation metabolite of Streptomyces nonhygroscopicus subsp. Fungi have a strong killing effect. It is suitable for the prevention and control of various fungal and bacterial diseases of various crops. Especially for fruit tree rot spot leaf spot disease; rice blast; soybean root rot; melon wilt; cotton verticillium wilt; jujube rust; grape white rot; ginseng Panax notoginseng black spot; It has special effects on fungal diseases such as disease, canker, gummosis, defoliation, and blight of forest seedlings. [0003] Azoxystrobin is a high-efficiency, broad-spectrum, new-type fungicide, which has multiple functions such as systemic conduction, prevention, protection, and treatment, and can inhibit ...
