Problems solved by technology

[0026] Although pyricloxazole or methoxyacrylate fungicides are used in the prior art, using pyridoxazole or methoxyacrylate fungicides alone will cause a narrow bactericidal spectrum, easily produce resistance, and use costs High, very unfavorable to the needs of large-scale broad-spectrum sterilization in agriculture, so it is urgent to develop new products to solve this technical problem

specific Embodiment approach

[0083] The invention is illustrated by, but not limited to, the following specific examples. The effect experiment of the present invention adopts the combination mode of indoor bioassay and field test. Unless otherwise specified, the ratios mentioned below are all percentages by mass.

[0084] The following formulation examples are further illustrations of the present invention, but the present invention is not limited to the formulation composition in this embodiment. The percentages in all formulation ratios are mass percentages. The original drugs and pesticide adjuvants used in the examples are purchased from the market, and the types of adjuvants are also known in the art.

Embodiment 1

[0085] Example 1: 16% Pyridoxazole · Enoxastrobin Microemulsion

[0086] Weigh 8g of pyridoxazole, 8g of oxastrobin, 8g of N-methylpyrrolidone, 17g of isopropanol, 4g of Nongru 600#, 6g of Nongru 1601#, and 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

[0087] Example 2: 20% Pyridoxazole · Enoxastrobin Suspension Concentrate

[0088] Weigh 15g of pyridoxazole technical substance, 5g of fenoxastrobin technical substance, 8g of FS3000 (phosphate ester anionic surfactant), 1g of TXC (sulfonate anionic surfactant), 0.3g of xanthan gum, 1g of silicic acid Magnesium aluminum, 2g ethylene glycol, 0.2g BIT (1,2-benzisothiazolin-3-one), 0.3g organically modified silicone defoamer, and deionized water to 100g. Add the above-mentioned raw materials into a high-shear emulsifier and shear for 10 minutes, and then grind them with a sand mill to obtain a suspending agent.

Abstract

The invention specifically relates to a composition with pyrisoxazole and methoxyacrylate bactericides as active components and application thereof, belonging to the field of pesticides. The composition further comprises a filling material and an auxiliary agent. The methoxyacrylate is any one selected from a group consisting of fenaminstrobin, kresoxim methyl, pyrametostrobin, (E)-2-[2-(2,5-dimethylphenoxy)benzylidene]-3-methoxyacrylate, metominostrobin and coumoxystrobin. The composition provided by the invention exerts good prevention and treatment effect on a plurality of plant diseases caused by oomycetes, ascomycetes, basidiomycetes and imperfect fungi, and can effectively control occurrence and harm of plant diseases like tomato gray mold, cucumber gray mold, cucumber powdery mildew, cucumber anthracnose, tomato leaf mold, Alternaria blotch of apple, wheat scab, cotton wilt, the Panama disease of bananas, banana wilt, rice bakanae disease and watermelon wilt. The composition has a wide bactericidal spectrum and effective synergistic effect, is reduced in dosage and application cost, and delays occurrence and development of resistance of pathogens to a single pesticide.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a composition containing pyridoxazole and methoxyacrylates and an application thereof. The composition is used for preventing and controlling various fungal diseases such as scab, leaf mold, anthracnose, early blight, gray mold and late blight of cereals, fruit trees or vegetables. 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 ...
