Embodiment 1

[0023] Example 1: 18% emulsifiable concentrate

[0024] The formula is composed of: 10% of active ingredient A, 8% of active ingredient B, 6% of emulsifier phenethylphenol polyoxyethylene ether, 4% of emulsifier calcium dodecylbenzenesulfonate, and 100% of solvent xylene %.

[0025] The preparation method is as follows: put all the materials into the batching kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.

Embodiment 2

[0026] Embodiment 2: 24% suspending agent

[0027] The formula is composed of: 8% active ingredient A, 16% active ingredient B, 3% wetting agent fatty alcohol polyoxyethylene ether, 4% dispersant EO-PO block polyether, 5% antifreeze propylene glycol, thickener Agent magnesium aluminum silicate 0.3%, water to make up to 100%.

[0028] The preparation method is: put the active ingredient, wetting agent, dispersant, antifreeze and water into the stirring tank, after fully stirring, pump the material into the sand mill for full grinding, after the grinding is completed, pump it into the high-speed shearing machine In the process, after adding the thickener, high-speed shearing is carried out, and the suspending agent is obtained after the shearing is completed.

Embodiment 3

[0029] Example 3: 36% water dispersible granules

[0030] The formula is composed of: 16% of active ingredient A, 20% of active ingredient B, 3% of wetting agent sodium lignosulfonate, 5% of dispersant naphthalenesulfonate formaldehyde condensate, 2% of disintegrating agent sodium sulfate, bonding Agent carboxymethyl cellulose 0.5%, filler kaolin make up to 100%.

[0031] The preparation method is as follows: after all the materials are mixed uniformly, pulverized by an airflow mill, mixed uniformly again, and then a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain the water-dispersible granules.

Abstract

The invention provides a synergistic antifungal composition containing metrafenone. The synergistic antifungal composition is characterized by being prepared from active ingredients A and B, wherein the A is the metrafenone, and the B is one or a combination of more than one of iprovalicarb, propineb, valiphenal, zoxamide, probenazole and fenhexamid; the synergistic antifungal composition further comprises additives which can be used for processing a pesticide preparation; the antifungal composition is prepared into a conventional pesticide preparation and is applied to prevention and control of plant fungal diseases.

Description

technical field [0001] The invention belongs to the technical field of pesticide application and relates to a pesticide composition, specifically a fungicidal composition containing metrafenone, which is used for preventing and treating fungal diseases of plants. Background technique [0002] In the process of agricultural production, plant fungal diseases (diseases caused by ascomycetes, basidiomycetes, deuteromycetes, and oomycetes) occur seriously, endangering plant stems, leaves and other vegetative organs, as well as reproductive organs such as fruits, seeds, and tubers, affecting plants. Photosynthesis affects the appearance of edible parts, causing a sharp decrease in crop yield and quality. When the disease is severe, it leads to crop failure. Therefore, plant fungal diseases have important control significance in production, and fungicides are the most economical, fast and effective method to prevent and control plant fungal diseases. [0003] The use of a single ...
