Problems solved by technology

[0007] In order to avoid problems such as the generation of drug resistance and the reduction of drug efficacy caused by the use of a single agent, the inventors have conducted in-depth research on the compounding and application of phenethamycin and hexaconazole, and found that the compounding of phenethamycin and hexaconazole , within a certain range of compounding ratio, it has obvious synergistic effect on the control of basidiomycetes, ascomycetes and deuteromycetes, especially for the control of rice sheath blight and rice false smut. The effect has been significantly improved, and the present invention has been completed through further research. At present, there has never been any report on the compounding of phenethamycin and hexaconazole

Embodiment 1

[0034] Embodiment 1: 12% phenethycin·hexaconazole suspension concentrate

[0035] 6% phenethycin, 6% hexaconazole, 5% polyoxyethylene polyoxypropylene block copolymer, 5% secondary alkyl sodium sulfate, 0.3% isothiazolinone, 0.2% silicone oil, 1.5% xanthan gum , Ethylene glycol 3%, deionized water to make up 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare a 12% phenethamycin·hexaconazole suspension.

Embodiment 2

[0036] Embodiment 2: 15% phenethycin hexaconazole microemulsion

[0037] 5% phenethycin, 10% hexaconazole, 11% tetramethylbenzene, 4% dibasic ester, 9% alkylphenol polyoxyethylene ether sulfosuccinate, 3.5% epichlorohydrin, ethylene glycol 2%, silicone oil 0.3%, deionized water make up 100%. The above-mentioned materials are mixed in proportion, and after being uniformly stirred by high-speed shearing, a 15% phenethromycin·hexaconazole microemulsion can be prepared.

Embodiment 3

[0038] Embodiment 3: 5% phenethycin·hexaconazole suspension concentrate water dispersible granule

[0039] 1% of phenethycin, 4% of hexaconazole, 6% of sodium lauryl sulfate, 5% of polycondensate of alkyl naphthalene sulfonate, 3% of ammonium sulfate, 0.5% of polyvinyl alcohol, and 100% of kaolin. The above-mentioned materials are mixed in proportion, air-jet pulverized, mixed evenly, kneaded and granulated, dried and sieved to prepare 5% phenethycin·hexaconazole suspension concentrate water-dispersible granules.

Abstract

The invention discloses an efficient bactericidal composition containing N,N-diethylphenazine-1-formamide and hexaconazole. The bactericidal composition is characterized in that effective components comprise the N,N-diethylphenazine-1-formamide and the hexaconazole, wherein the weight ratio of the N,N-diethylphenazine-1-formamide to the hexaconazole ranges from (1 to 30) to (20 to 1); the weight percent content of the N,N-diethylphenazine-1-formamide to the hexaconazole in the composition is 1 to 75 percent. The bactericidal composition has a relatively good prevention and control effect on rice sheath blight disease and rice false smut.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a high-efficiency bactericidal composition containing phenethamycin and hexaconazole. Background technique [0002] Phenethylmycin, whose chemical name is: N,N-diethylphenazine-1-carboxamide, is a biologically active fungicide obtained by fermentation and cultivation of Pseudomonas napus. Against rapeseed blight, cucumber downy mildew and powdery mildew, wheat root rot, rice sheath blight, bean anthracnose, tomato leaf mold, wheat take-all, cabbage black spot, tobacco black shank, tomato Many vegetable and grain crop pathogenic fungi, such as Botrytis cinerea and Asparagus stem blight, have strong inhibitory effects, and can colonize the rhizosphere of various crops, showing the potential for application in biological control. [0003] Hexaconazole is a triazophos fungicide, a sterol demethylation inhibitor, and has systemic, protective and therapeutic effects on diseases cau...
