Embodiment 1、60

[0025] Example 1, 60.5% metconazole · flufenapyramide · pyraclostrobin wettable powder (1:60:60)

[0026] 0.5% metconazole, 30% flufenapyramide, 30% pyraclostrobin, 9% fatty acid polyoxyethylene ether, 1% calcium salt of alkylbenzenesulfonate, and bentonite to make up to 100%. The above ingredients were mixed evenly, pulverized by a jet mill, and stirred for 30 minutes to obtain a 60.5% wettable powder of metconazole·flufenapyramide·pyraclostrobin.

Embodiment 2、36

[0027] Example 2, 36% metconazole · flufenapyramide · pyraclostrobin suspension concentrate (5:30:1)

[0028] Meconazole 5%, Flufenapyramide 30%, Pyraclostrobin 1%, Polypropylene Glycol Ethylene Oxide Adduct 7%, Sodium Dodecyl Benzene Sulfonate 0.4%, Xanthan Gum 0.1% , ethylene glycol 2%, water to make up to 100%. Grind the active ingredients and emulsifier in a ball mill for 2 hours, then pump them into a shearing machine and add antifreeze, thickener, and water to mix, and mix evenly through high-speed shearing to obtain 36% metconazole Suspension concentrate of flufenapyrazole pyraclostrobin.

Embodiment 3、30

[0029] Example 3, 30% metconazole · flufenapyramide · pyraclostrobin aqueous emulsion (10:10:10)

[0030] Meconazole 10%, Flufenapyr 10%, Pyraclostrobin 10%, Alkylphenol Ethoxylates 16%, Tea Saponin 10%, Propylene Glycol 0.5%, Xanthan Gum 1%, Water Top Up 100 %, according to the conventional preparation method to prepare the metconazole · flufenapyramide · pyraclostrobin aqueous emulsion with a mass percent content of 30%.

Abstract

The invention relates to a sterilizing composition containing metconazole, fluxapyroxad and pyraclostrobin. The sterilizing composition is characterized by containing 1 to 60 percent of metconazole, 1to 60 percent of fluxapyroxad and 1 to 60 percent of pyraclostrobin; and the sterilizing composition is used for preventing and treating wheat scab, wheat powdery mildew, wheat rust, wheat sharp eyespot, rice blast, rice bakanae disease and crop botrytis, and the synergistic effect is remarkable.

Description

Technical field: [0001] The invention belongs to the field of agricultural fungicides, and in particular relates to a fungicidal composition containing metconazole, flufenapyr and pyraclostrobin and an application thereof. Background technique: [0002] Pesticide use experience shows that repeated application of a single active ingredient to control harmful fungi will cause fungi to develop resistance, which is not conducive to further improvement of drug efficacy. Therefore, in order to reduce the selectivity of fungi, the most common method at present is to use different active ingredients. mixture to control harmful fungi. And the combination of active ingredients with different mechanisms of action can not only delay the emergence of resistance, but also reduce the amount of application and control costs. After research by the inventors, the compounding of the fungicides metconazole, flufenapyramide and pyraclostrobin with different mechanisms of action has a significan...
