Embodiment 1

[0043] Embodiment 1: 15.5% prothioconazole · kasugamycin suspension concentrate

[0044] Weigh 0.5% prothioconazole, 15% kasugamycin, 2% naphthalenesulfonate formaldehyde condensate, 1% nonylphenol polyoxyethylene ether, 6% ethylene glycol, 0.25% XG, 0.4% silicone disinfectant Foaming agent, 0.4% sodium benzoate, deionized water added to 100% parts by weight. Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours to reach a fineness of 1-5 microns to prepare 15.5% prothioconazole·kasulei mold Suspending agent.

Embodiment 2

[0045] Embodiment 2: 22% prothioconazole · kasugamycin wettable powder

[0046] Weigh 2% prothioconazole, 20% kasugamycin, 3% sodium dodecylbenzenesulfonate, 6% sodium dodecylnaphthalenesulfonate, 6% white carbon black, 10% anhydrous sodium sulfate, Kaolin is added to 100% by weight. Preparation method: Mix all the combinations uniformly, first pass through mechanical pulverization, then jet pulverization, and then mix uniformly to prepare 22% prothioconazole·kasugamycin wettable powder.

Embodiment 3

[0047] Embodiment 3: 42% prothioconazole · kasugamycin suspension concentrate

[0048] Weigh 2% prothioconazole, 40% kasugamycin, 4% sodium polycarboxylate, 3% fatty acid polyoxyethylene ether, 6% ethylene glycol, 0.3% XG, 0.4% silicone defoamer, 0.4% Sodium benzoate and deionized water are added to 100% by weight. Preparation method: Mix the components, mix them evenly by high-speed shearing, and then sand them with a sand mill for 2-3 hours to reach a fineness of 1-5 microns, and then 30% prothioconazole-kasugamycin can be prepared suspending agent.

Abstract

The invention discloses a bactericidal composition and application thereof and relates to the technical field of pesticide combination. Effective ingredients of the bactericidal composition include prothioconazole A and antibiotic bactericide B, wherein the weight ratio of the prothioconazole A to the antibiotic bactericide B is 1:30-30:1. The antibiotic bactericide B can be kasugamycin, polyoxin, phenazine-1-carboxylic acid, streptomycin or validamycin. The prothioconazole A and the antibiotic bactericide B have obvious synergistic effects, the application amount of single dosage can be effectively reduced, good effect is played on enlargement on a bactericidal spectrum and delay on plant resistance to insecticide, a lasting period can be further prolonged, and the bactericidal composition has obvious promotional value. Assistant ingredients allowed in other pesticides can be added into the bactericidal composition to process any dosage form of insecticide. The bactericidal composition can effectively prevent and control rice sheath blight disease, rice blast, false smut, wheat rust, powdery mildew and the like.

Description

technical field [0001] The invention relates to a fungicide composition and its application, in particular to a fungicide composition with prothioconazole and antibiotic fungicides as active ingredients and its application, and belongs to the technical field of compound pesticides. Background technique [0002] In agricultural production, the healthy growth of crops is not only affected by insects and weeds, but also the prevention and control of diseases is very important. With the strengthening of environmental protection concepts and the implementation of sustainable development strategies, high efficiency, low toxicity, high activity, and low residue have become an inevitable trend in the development of pesticides. However, even if high-efficiency fungicides are used alone for a long time, it is easy to cause disease resistance, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to sustainable development ...
