Embodiment 1

[0088] Weigh 100 grams of fluconazole hydroxylamine, 100 grams of metconazole, 50 grams of alkylphenol polyoxyethylene ether phosphate, 50 grams of sodium lignosulfonate, 30 grams of alkylphenol formaldehyde resin polyoxyethylene ether, 15 gram of bentonite, 10 grams of xanthan gum, 50 grams of urea, 1 gram of benzoic acid, 8 grams of hexanol, and deionized water added to 1000 grams by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 After the thickness is less than 10 μm, a 20% flufenapyramide·meconazole suspension was prepared.

Embodiment 2

[0090] Weigh 80 grams of fluconazole hydroxylamine, 160 grams of tebuconazole, 55 grams of sodium alkyl polyoxyethylene ether sulfonate, 15 grams of alkylphenol formaldehyde resin polyoxyethylene ether, 20 grams of magnesium aluminum silicate, 40 grams of ethyl alcohol Diol, 3 grams of benzoic acid, 15 grams of butanol, and deionized water are added to 1000 grams by weight. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 After the thickness is less than 10 μm, a 24% flufenapyr-tebuconazole suspension was prepared.

Embodiment 3

[0092] Weigh 100 grams of flufenapyramide, 150 grams of prothioconazole, 40 grams of alkylphenol polyoxyethylene ether phosphate, 50 grams of polyoxyethylene polyoxypropylene block copolymer, 40 grams of Tween-60#, 30 grams of agricultural milk 700#, 30 grams of calcium dodecylbenzene sulfonate, 15 grams of organic bentonite, 12 grams of polyvinyl alcohol, 10 grams of BHT, cottonseed oil to make up 1000 grams. The above raw materials are mixed and sand-milled with a sand mill until the particle size is less than 5 μm to prepare 25% flufenapyramide prothioconazole dispersible oil suspension concentrate.

Abstract

The invention discloses a sterilization composition containing pydiflumetofen and triazole fungicide, and application thereof to prevention and control of various fungus diseases of crops. The composition is prepared from a first active ingredient of pydiflumetofen, a second active ingredient of triazole fungicide including one kind of materials or several kinds of materials from tebuconazole, hexaconazole, difenoconazole, epoxiconazole, flusilazole, triticonazole, metconazole, ipconazole, propiconazol and prothioconazole, and various auxiliary agents; the weight ratio of the first active ingredient to the second active ingredient is 1:50 to 30:1; the ratio of the sum weight of the first ingredient and the second ingredient to the total weight of the composition is 1 percent to 90 percent. The composition can be prepared into agricultural allowable suspension, dispersible oil suspension, wettable powder, water dispersion particles, missible oil and microemulsion. The sterilization composition has the advantages that the ingredients are reasonable; the sterilization effect is good; the activity and the sterilization effect are not the simple accumulation of the activity of all ingredients. Compared with the existing single preparation, the sterilization composition has the advantages that the obvious sterilization effect is realized; the obvious synergistic effect can be achieved; the safety on the crops is high. The sterilization composition has the obvious prevention and control effects on fusarium graminearum, marssonina coronaria, cercosproa musae, rhizotonia cerealis, rhizoctonia solani and the like.

Description

technical field [0001] The invention relates to a bactericidal composition containing flufenapyramide and triazole fungicides, which is composed of the first active ingredient flufenapyramide, the second active ingredient triazole fungicides and auxiliary agents, and belongs to the pesticide complex. With the field of application technology. Background technique [0002] Flumetofen, English common name pydiflumetofen, chemical name: 3-(difluoromethyl)-N-methoxy-1-methyl-N-[(RS)-1-methyl-2-(2 , 4,6-trichlorophenyl)ethyl]pyrazole-4-carboxamide. It is a succinate dehydrogenase inhibitor fungicide developed by Syngenta Crop Protection Co., Ltd., Switzerland. Flufenapyramide has a broad spectrum and high efficiency, and is suitable for a variety of crops, especially for leaf spot and powdery mildew, and for diseases that are difficult to control in agriculture, such as Botrytis pp. and Sclerotinia spp. ) and Corynespora (Corynespora spp.) and other pathogenic bacteria are high...
