Problems solved by technology

[0004] After searching, the applicant found that there is currently no report on the mixture of flufenapyramide and mancozeb for the prevention and treatment of plant fungal diseases. Further tests found that the compounding of flufenapyl hydroxylamide and mancozeb with different action mechanisms , has an unexpected effect, and has a good control effect on crop black spot, anthracnose, brown spot, powdery mildew, brown rot, sclerotinia, scab, gray mold, and the synergistic effect is obvious. Reduced dosage, reduced control cost, safe for crops

Embodiment 1

[0098] Weigh 2% flufenapyramide, 20% mancozeb, 4% fatty alcohol polyoxyethylene ether phosphate, 6% sodium lignosulfonate, 34% sodium alkyl sulfate, add enough talcum powder to 100% parts by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 22% flufenapyramide·mancozeb wettable powder.

Embodiment 2

[0100] Weigh 5% flufenapyramide, 30% mancozeb, 5% sodium lignosulfonate, 8% sodium alkylnaphthalene formaldehyde condensate sulfonate, 5% sodium lauryl sulfate, and add enough kaolin to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 35% flufenapyramide·mancozeb wettable powder.

Embodiment 3

[0102] Weigh 2% flufenapyramide, 20% mancozeb, 3% polycarboxylate GY-D06, 6% sodium alkylnaphthalene sulfonate, 3% pull open powder BX (sodium dibutylnaphthalene sulfonate ), 3% sodium alkylsulfonate, 3% bentonite, clay added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 22% flufenapyramide·mancozeb water-dispersible granules.

Abstract

The invention discloses a sterilization composition containing pydiflumetofen and mancozeb and application of the sterilization composition. The effective active ingredients include pydiflumetofen asthe first active ingredient and mancozeb as the second active ingredient, the weight ratio of the first active ingredient to the second active ingredient is (1 to 60)-(60 to 1), preferably (1 to 30)-(30 to 1). The composition can be prepared into agriculturally acceptable wettable powder, a water dispersible granule, a suspending agent, a suspension emulsion, an aqueous emulsion, a micro emulsion,a micro-capsule suspending agent, a micro-capsule suspending-suspending agent, a dispersible oil suspending agent. The composition is reasonable in component and good in sterilization effect, and theactivity and the sterilization effect are not simple superposition of the activities of all components; and compared with an existing single preparation, the sterilization composition has an obvioussterilization effect and a remarkable synergistic effect and is safe to crops. The sterilization composition has remarkable prevention and treatment effects to black spots, anthracnose, brown spots, powdery mildew, brown rot, stalk break, venturia inaequalis and gray mold of the crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient flufenapyramide, a second active ingredient mancozeb and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Flumetofen, English common name pydiflumetofen, chemical name: 3-(difluoromethyl)-N-methoxy-1-methyl-N-[(RS)-1-methyl-2-(2 , 4,6-trichlorophenyl)ethyl]pyrazole-4-carboxamide. Flufenapyramide is a pyrazole amide fungicide discovered, developed and produced by Syngenta. It was launched in 2017. It is the latest product to be launched among SDHI fungicides. Fluconazole hydroxylamide is highly efficient and broad-spectrum, suitable for cereals, corn, soybeans, rapeseed, vegetables and special crops, etc., to control gray mold, brown spot, leaf spot, sclerotinia, powdery mildew, scab Many diseases, etc. Among all chemical types of products, flufenapyramide has the highest activity against leaf...
