Embodiment 1

[0030] Example 1: 10% difenoconazole·HSAF oil suspension concentrate (1:3)

[0031]The components of the fungicidal composition containing difenoconazole and HSAF are: 2.5% of difenoconazole, 7.5% of HSAF, 5% of phenethylphenol polyoxyethylene ether, 8% of sodium lignosulfonate, Epoxidized soybean oil 5%, organic bentonite 5%, polyglycolic acid alkyl ether 0.1%, oleic acid methyl ester to 100%.

[0032] After fully mixing HSAF and methyl oleate, add the other above-mentioned materials (except organic bentonite) into the reactor mixer, stir evenly, and inject the materials into a multi-stage sand mill for grinding. The fineness of the materials after grinding is After 98% pass through 1-5μm, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, a 10% difenoconazole·HSAF oil suspension can be made.

Embodiment 2

[0033] Example 2: 11% difenoconazole·HSAF water dispersible granules (1:10)

[0034] The components of the fungicidal composition containing difenoconazole and HSAF are: difenoconazole 1%, HSAF 10%, naphthalenesulfonate Morwet EFW 3%, polycarboxylate Agrilan 700 10%, sulfuric acid Ammonium 5%, polyvinyl alcohol 5%, borax 2%, add kaolin to 100%.

[0035] After adsorbing and mixing HSAF and filler, add the above-mentioned other materials into the conical mixer and mix evenly, and then pulverize through the jet mill, and then mix the pulverized material through the conical mixer, and the fineness of the mixed material is 98%. 325-mesh standard sieve, put into a kneader to knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate, after granulation, dry and sieve to obtain 11% difenoconazole·HSAF Water dispersible granules.

Embodiment 3

[0036] Example 3: 21% difenoconazole·HSAF water dispersible granules (2:1)

[0037] The components of the fungicidal composition containing difenoconazole and HSAF are: 14% of difenoconazole, 7% of HSAF, 8% of sodium lignosulfonate, 2% of sodium lauryl sulfate, and 5% of ammonium sulfate , polyvinyl alcohol 5%, borax 2%, Dow Corning 3150 0.2%, add diatomaceous earth to 100%.

[0038] After adsorption and mixing of difenoconazole and fillers, add the above-mentioned other materials into the conical mixer and mix evenly, and then pulverize through the jet mill, and then mix the pulverized materials through the conical mixer, and the mixed materials are fine 98% pass through a 325-mesh standard sieve, put into a kneader and knead into a plastic material, and finally put this material into an extrusion granulator to extrude and granulate, after granulation, dry and sieve to obtain 21% diphenoxymethyl Cycloconazole · HSAF water dispersible granules.

Abstract

The invention discloses a difenoconazole and biological antifungal substance HSAF (heat stable antifungal factor) containing fungicidal composition and application thereof. The fungicidal compositiontakes difenoconazole and HSAF as main effective components, and a mass ratio of difenoconazole to HSAF is 1:25-25:1. The fungicidal composition has synergistic effects in the above ratio range, drug resistance of germs is overcome and retarded, and high fungicidal speed, great prevention effects, long efficacy lasting period and low application cost are realized. The fungicidal composition is capable of preventing and controlling various crop fungal and oomycetes diseases and evidently superior to single agents in prevention and control effects on fungal diseases such as black spot, rot, scab,anthracnose, rust disease and the like of fruit trees and vegetables.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition with difenoconazole and a biological antibacterial substance HSAF as main active ingredients and an application thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the structure and mode of planting have changed. The planting area of ​​green and efficient fruit trees, vegetables and other horticultural crops has gradually expanded, the varieties have become increasingly rich, and the economic output value has increased rapidly. In the process of breeding and promotion of horticultural crop varieties, the quality of fruits and vegetables (including nutritional value, taste and appearance characteristics, etc.) In addition, fruit trees are perennial crops, and vegetables are cultivated repeatedly, all of which cause abundant pathogenic bacteria in the field. Therefore, the occurrence a...
