Embodiment 1

[0029] Example 1: 14% imidamide·HSAF water dispersible granule (1:6)

[0030] The components of the fungicidal composition containing imidamide and HSAF are: imidamide 2%, HSAF 12%, naphthalenesulfonate Morwet EFW 3%, polycarboxylate Agrilan 700 10%, ammonium sulfate 5%, polyethylene Alcohol 5%, borax 2%, polydimethoxyalkane 1%, add kaolin to 100%.

[0031] 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 the 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 14% imidamide·HSAF water dispersible granules agent.

Embodiment 2

[0032] Embodiment 2: 14% imidamide·HSAF oil suspension concentrate (6:1)

[0033]The components of the germicidal composition containing imidamide and HSAF are: imidamide 12%, HSAF 2%, phenethyl phenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 10%, organic Bentonite 3%, Dow Corning 3150 0.2%, Polyglycolic acid hydrocarbyl ether 1%, Methyl oleate to 100%.

[0034] After fully mixing HSAF and methyl oleate, add 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 After 98% passes through 1-5μm, the material is discharged, and then the material and the pre-dissolved organic bentonite are put into a high-shear emulsification kettle. After emulsification, a 14% imidamide·HSAF oil suspension agent can be prepared.

Embodiment 3

[0035] Example 3: 14% imidamide·HSAF aqueous emulsion (6:1)

[0036] The components of the germicidal composition containing imidamide and HSAF are: imidamide 12%, HSAF 2%, xylene 15%, isopropanol 3%, calcium lauryl sulfate 2%, polyvinyl alcohol 5%, Xanthan Gum 0.3%, Dow Corning 3150 0.2%, add water to 100%.

[0037] Mix imidamide, HSAF, and xylene evenly under mechanical stirring to form an oil phase; put isopropanol, calcium lauryl sulfate, polyvinyl alcohol, xanthan gum (dissolved in advance) and water into the emulsification and dispersion kettle , stir at high speed for 10-30 minutes; then put the oil phase into the emulsification and dispersing kettle, and stir for 20-100 minutes to make it into a uniform emulsion, that is, 14% imidamide·HSAF water emulsion is obtained.

Abstract

The invention discloses a sterilizing composition comprising prochloraz and biological antibacterial substance HSAF (heat stable antifungal factor) and application of the sterilizing composition. Theprochloraz and the HSAF are main effective components of the sterilizing composition. The mass ratio of the prochloraz to the HSAF ranges from 1:10 to 10:1. The sterilizing composition has synergisticinteraction effect within the matching range, overcomes and delays drug resistance of bacteria, and has high sterilization speed, good prevention and treatment effect, long lasting period and low application cost. The sterilizing composition can be used for preventing and controlling various crop fungus and oomycete diseases, especially fungus diseases such as black spots, anthracnose, scabs andrust diseases of pear trees and apple trees, and has obviously better prevention and control effect than a single agent.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition with imidamide and a biological antibacterial substance HSAF as main active ingredients and an application thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, consumers have higher and higher requirements for the quality of agricultural products, especially for the quality of fruits and vegetables (including safety, nutritional value, taste and appearance characteristics, etc.). Fruit trees are perennial crops, and vegetables are cultivated repeatedly, resulting in abundant pathogenic bacteria in the field, serious diseases, especially fungal and oomycete diseases, which are becoming more and more serious, and the commodity rate of fruit and vegetable products is not high, resulting in huge economic losses. In order to effectively control the harm of crop diseases and improve the app...
