Embodiment 1

[0048] Example 1 21% downy mildew triethylphosphonate aluminum soluble granules

[0049] The formula is: downy mildew 1%, aluminum triacephosphonate 20%, dispersant methyl naphthalenesulfonate formaldehyde condensate sulfate 2.0%, sodium methylene naphthalenesulfonate formaldehyde condensate 4.0%, wetting agent a-sulfo fatty acid methyl ester 1.0%, sodium lauryl sulfate 1.5%, binder maltodextrin 3.0%, stabilizer tricalcium phosphate 2.5%, pH regulator citric acid 0.4%, filler bentonite 25%, potassium chloride increased to 100%.

[0050] The preparation method is: downy mildew, aluminum triethylphosphonate, dispersant, wetting agent, stabilizer, filler in the mixer to mix evenly, through the air flow pulverizer crushed to a particle size of 15-20μm, secondary mixing, mixed evenly, add water kneading, after extrusion granulation, drying, sieving to obtain downy mildew triethylphosphonate aluminum soluble granules.

Embodiment 2

[0051] Example 2 31% downy mildew triethylphosphonate aluminum soluble granules

[0052]The formula is: downy mildew 1%, aluminum triacephosphonate 30%, dispersant polycarboxylate sodium salt 4.0%, naphthalenesulfonate formaldehyde condensate sodium salt 2.5%, wetting agent alkylphenol polyoxyethylene ether sodium sulfate 1.5%, sodium dodecylbenzenesulfonate 1.0%, binder sucrose 4.0%, stabilizer sodium aluminum aluminate 2.5%, pH regulator sodium benzoate 0.5%, filler potassium sulfate 25%, light calcium carbonate added to 100%. The preparation method is the same as Example 1.

Embodiment 3

[0053] Example 3 80% downy mildew triethylphosphonate aluminum soluble granules

[0054] The formula is: downy mildew 5%, aluminum triethylphosphonate 75%, dispersant sodium polycarboxylate 4.0%, formaldehyde formaldehyde sodium salt of naphthalene sulfonate 4.0%, wetting agent alkylphenol polyoxyethylene ether sodium sulfate 2.0%, sodium a-olefin sulfonate 1.0%, binder polyvinyl alcohol 5.0%, stabilizer silica 3.0%, pH regulator sodium acetate 0.5%, filler kaolin added to 100%.

[0055] The preparation method is the same as Example 1.

Abstract

The invention discloses soluble granules containing propamocarb and fosetyl-aluminum and application of the soluble granules. The active pharmaceutical ingredients of the soluble granules are propamocarb and fosetyl-aluminum, and the content of the active ingredients of the medicine is 10-85 wt%. The soluble granule disclosed by the invention is high in sterilization efficiency and small in dosage, the drug resistance of diseases is delayed, the lasting period of the drug is prolonged, and the soluble granule has special effects on downy mildew and epidemic diseases on vegetables and is beneficial to sustainable development of the environment; meanwhile, the problem that fosetyl-aluminum is easy to flocculate is finally relieved or eliminated by optimizing and screening the types and proportions of the auxiliaries, and the fosetyl-aluminum suspending agent has the advantages of being high in suspension rate, good in stability and good in tank mixing compatibility.

Description

Technical field [0001] The present invention relates to a soluble granule containing downy mildew and aluminum triethylphosphonate and application thereof, belonging to the field of pesticide technology. Background [0002] Downy mildew (Propamocarb, chemical name: 3-dimethylaminopropyl propane propanoate) is an aliphatic fungicide, low toxicity, safe, with good local endorption, after treating the soil can be quickly absorbed by the root system and transported upwards to the whole plant, stem and leaf spray treatment, can be quickly absorbed by the leaves to play a protective role. The mechanism of action of downy mildew is to inhibit the synthesis of phosphoric acid and fatty acids in the membrane components of pathogenic bacteria, inhibit the growth and spread of hyphae and the formation of sporangia and spore germination. Downy mildew is a broad-spectrum fungicide, which is particularly effective against algal fungi, and has a good killing effect on fungi such as tox mold, d...
