Problems solved by technology

[0006] In the above-mentioned patents, sulfur is used as an important component of the fungicide. Although it can solve the problem of non-systemic protective sterilization, it cannot achieve a synergistic effect because the components of the composition are relatively single.
In addition, because the

Embodiment 1

[0046] Indoor toxicity test of Cyazofamid and sulfur compound against cucumber powdery mildew:

[0047] Test object: Cucumber powdery mildew

[0048] Experimental method: use potting method, use a brush dipped in distilled water at about 10°C to wash the sporangia on the back of cucumber leaves with powdery mildew bacteria collected from the field, and make 3×10 5 sporangia / mL suspension. Select two cucumber seedlings at the true leaf stage with the same growth, and select 5 pots of melon seedlings for each treatment, and spray them with a Potter spray tower at a pressure of 50PSI, about 5mL per pot. Five concentration gradients were set for each agent, and the same amount of water was sprayed as the blank control. Spray and inoculate cucumber downy mildew 24 hours after chemical treatment. After inoculation, place cucumber seedlings in an artificial climate box (relative humidity 100%, temperature 15-20°C) for cultivation, and keep the temperature 15-24°C after 24 hours, an...

Embodiment 3

[0088] Indoor toxicity determination of sulfur and pyraclostrobin compound against banana scab:

[0089] Experimental method: Determination by mycelial growth rate method, referring to "Pesticide Indoor Bioassay Test Guidelines: Fungicides". The test agent was added into the quantitative PSA medium according to different doses, and a series of drug-containing medium was prepared, and each concentration was treated with 4 repetitions. Put the pre-cultured banana scab bacteria block (the diameter of the hole punch is 4mm) in the center of the plate containing the drug-containing PSA medium, and cultivate it at a constant temperature (26.0°C) without light. After 15 days, the colony diameter was measured and compared with the blank control.

[0090] Calculate the antibacterial effect of each chemical treatment on the growth of banana scab mycelium, use the DPS data processing system to analyze the significant difference of the test results and calculate the EC50 of the test chem...

Abstract

The present invention discloses a sulfur-containing bactericidal agent composition and application thereof, the effective sterilization components include a component A and a component B, the component A is one or more substance selected from the group consisting of tebuconazole, cyazofamid or pyraclostrobin, the component B is sulfur, the mixing mass ratio of component A to component B is 99:1-1:99; the sulfur-containing bactericidal agent composition also includes one substance or a mixture of a plurality of substances selected from the group consisting of a thickening agent, a solvent, a surface active agent, a dispersing agent, a film forming agent or a filler. The sulfur-containing bactericidal agent composition is efficient, broad-spectrum, multi-function and biological reasonable, and is conducive to the progression of formation and development of pathogenic bacteria drug resistant effect on the bactericidal agent to prolong the service life; the sulfur-containing bactericidal agent composition can be made into various formulations, also has a protective effect, therapeutic effect, systemicity and rain erosion resistance, and has a wide application range.

Description

technical field [0001] The invention relates to a fungicide composition, in particular to a fungicide composition containing sulfur and its application. Background technique [0002] Fungicides are a class of pesticides used to prevent and control plant diseases caused by pathogenic microorganisms. The emergence of fungicides has greatly reduced the losses caused by plant diseases to agriculture. According to the raw materials, fungicides can be divided into inorganic fungicides, organic sulfur fungicides, substituted benzene fungicides, antibiotic fungicides and compound fungicides. [0003] Among them, sulfur is an important variety of inorganic fungicides. It has bactericidal and acaricidal effects, and has good control effects on wheat, melon, nightshade, banana and grape powdery mildew. The bactericidal mechanism of sulfur is the process of electron transfer between cytochrome b and c in the redox system, which can capture electrons and interfere with normal redox. ...
