Problems solved by technology

[0006] Using pyridoxazole or amide fungicides alone will result in narrow bactericidal spectrum, easy to produce resistance, and high cost of use, which is very unfavorable for large-scale broad-spectrum sterilization in agriculture. Therefore, it is urgent to develop new products to solve this problem. technical problem
[0007] And so far, there is no literature disclosing the mixing of pyridoxazole and amide fungicides, and the resulting composition is used to prevent and treat agricultural diseases, thereby delaying the development of drug resistance of pathogenic bacteria and reducing farmers' drug costs

specific Embodiment approach

[0074] The following examples are only to further illustrate the present invention, but are not intended to limit the present invention to these specific embodiments. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0075] The inventor mixed pyroxazole with flufenoxamide, chlorophenamide, fluoxetamide, Isofetamid, bixafen, and Pydiflumetofen, and carried out indoor activity determination tests on cucumber gray mold. The specific test conditions and results as follows:

[0076] Test crop: cucumber (variety: Shandong Mici)

[0077] Control object: Botrytis (Pseudoperonospora cubensis)

[0078] Environmental conditions: This experiment was carried out in the greenhouse of the pesticide research base of Shenyang Sinochem Pesticide Chemical R&D Co., Ltd. Cucumber seedlings at the one-leaf-one-heart stage with uniform growth were selected, and no other fungi...

Embodiment 1

[0117] Embodiment 1: 4% pyridoxazole·fluphenamide microemulsion (ME)

[0118] Weigh 2g of pyridoxazole technical material, 2g of fluphenamide technical material, 5g of N-methylpyrrolidone, 10g of isopropanol, 4g of agricultural milk 600#, 6g of agricultural milk 1601#, add water to make up to 100g. Add the original medicine, solvent and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain a Good microemulsion.

Embodiment 2

[0119] Embodiment 2: 60% pyridoxazole·fluphenamide water dispersible granule (WG)

[0120] Weigh 10g of pyridoxazole technical substance, 50g of fluorophenyl ether amide technical substance, 5g of sodium salt of alkylnaphthalenesulfonic acid condensation polymer, 14g of ammonium sulfate, 2g of alkylnaphthalenesulfonate and anionic wetting agent mixture, 0.4g Sodium Benzoate and 18.6g Corn Starch. Mix evenly, after jet crushing, granulate in a granulator, then dry and sieve to obtain granular products.

Abstract

The invention specifically relates to a pesticide composition and application thereof, belonging to the technical field of pesticides. The composition comprises active components, a filling material and an adjuvant, wherein the active components are pyrisoxazole and an amide bactericide. The composition is mainly used for preventing and treating cucumber gray mold, cucumber powdery mildew, strawberry powdery mildew, strawberry gray mold, tomato gray mold, tomato leaf mold, tomato early blight, grape gray mold, grape powdery mildew, grape anthracnose, pepper anthracnose, pepper blight, mango anthracnose, potato early blight, loose smut of wheat and so on. The composition has many action mechanisms and sites, and can effectively delay the occurrence and development of the drug resistance ofpathogenic bacteria; and the composition is simple in preparation process and low in cost, and produces remarkable economic benefits.

Description

technical field [0001] The invention belongs to the field of pesticides. It relates to a bactericidal composition and its application, in particular to a composition containing pyridoxazole and an amide fungicide and its application. Background technique [0002] Plant diseases are divided into two types: infectious and non-infectious. Among all infectious diseases, fungal diseases are the most numerous, accounting for more than 70% of all diseases. Fungal diseases include Ascomycetes, Basidiomycetes, Deuteromycetes, and Oomycetes, which often cause symptoms such as root rot, stem rot, fruit (ear) rot, branch withering, and leaf spots. When crops are harmed by fungal infection, it will not only affect the quality of the crops, but also affect the yield of the crops, resulting in economic losses and endangering the processing industry and food industry that use agricultural products as raw materials. [0003] Plant diseases caused by oomycetes, ascomycetes, basidiomycetes a...
