Problems solved by technology

[0002] Cyazofamid (Cyazofamid) chemical name 4-chloro-2-cyano-5-p-methylphenyl-imidazole-1-N, N-dimethylsulfonamide, belongs to imidazole fungicides, is a mitochondrial respiration inhibitor , has effects on all growth stages of oomycetes, and is active against metalaxyl-resistant or sensitive bacteria. It has certain systemic and therapeutic activities, long-lasting, rain-resistant, and is effective for crops, humans, and the environment. Safe, but long-term single use will inevitably make bacteria resistant to it
[0003] Thiocarbamate fungicides include mancozeb (Mancozeb), chemical name ethylene bis-dithiocarbamate manganese and zinc complex salt; Zinc (Zineb), chemical name ethylene bis-disulfide Zinc carbamate; Metriam, chemical name tris[ammonia(ethylenebis(dithiocarbamate)zinc(2+))][tetrahydro-1,4,7-dithiadiazepine Oct-3,8-dithione], polymer; Propineb, chemical name propenyl bisdithiocarbamate zinc; Thiram, chemical name tetramethylthiuram disulfide This type of fungicide belongs to the protective fungicide with a wide bactericidal spectrum and has good protective activity, but the therapeutic activity of this type of fungicide is very weak, and the therapeutic effect is not obvious. It is not only poor in quick effect, but also easy to treat when used alone. It produces resistance and has little effect. From the perspective of economy and effect, farmers seldom use it alone, so its use is limited to a certain extent.
At present, there is no report on the compounding of Cyazofamid and thiocarbamate fungicides

Embodiment 1

[0028] Example 1: Determination of the antibacterial activity of Cyazofamid and Dysenzinc single mixture on Chinese cabbage downy mildew

[0029] Test method: Greenhouse potted cabbage seedlings were used to 2-3 leaf stage, foliar spray treatment was carried out according to the designed dosage of chemicals, and the control was sprayed with the same amount of water. After 24 hours, inoculate downy mildew of cabbage, cultivate under moisturizing conditions, and investigate the results when the blank control without spraying is fully sick. The test results are shown in Table 2.

[0030] Table 2 Determination of antibacterial activity of cyfamidazole and dysenzine single mixture against cabbage downy mildew

[0031]

[0032] It can be seen from Table 2 that the compound of Cyfamid and Zinc has a good indoor antibacterial activity against downy mildew of cabbage, and the antibacterial activity is higher than that of a single agent.

Embodiment 2

[0033] Example 2: Determination of the antibacterial activity of Cyazofamid and Mancozeb single mixture against grape downy mildew

[0034] Using greenhouse cuttings of grape seedlings, the antibacterial effect of cyazofamid and mancozeb single mixture on grape downy mildew was determined. When the grape seedlings grow to 3 to 4 leaves, choose 2 leaves with uniform growth, use a manual sprayer for foliar chemical spray treatment, and spray the same amount of water for the control. After 24 hours, the pathogenic bacteria were inoculated, and the results were investigated after culturing for 7 days under moisturizing conditions. The results are shown in Table 3.

[0035] Table 3 Determination of antibacterial activity of cyfamidazole and mancozeb single mixture against grape downy mildew

[0036]

[0037] It can be seen from Table 3 that the compound of Cyazofamid and Mancozeb has good indoor antibacterial activity against Phytophthora downy mildew, and the antibacterial act...

Embodiment 3

[0038] Example 3: Pharmacodynamic test of Cyazofamid and Prosenzinc single mixture to control tomato late blight

[0039] Cyfamid Prosenzinc 74% WP, comprising by weight the following components:

[0040] Cyazofamid 4%

[0041] Prosenzinc 70%

[0042] Sodium dodecylbenzenesulfonate 2.5%

[0043] White carbon black 10%

[0044] Wood calcium 4%

[0045] Pulled powder 3%

[0046] K12 3%

[0047] Light calcium carbonate balance

[0048] The above components are fully mixed according to the formula ratio, and after being pulverized by an ultrafine pulverizer, a 74% Cyfamid-Prosenzinc wettable powder is obtained.

[0049] Using potted tomato seedlings in greenhouse, the control effects of Cyfamid, Prosenzinc and the above mixtures on tomato late blight were determined. When the tomato grows to 3 to 4 leaves, select the leaves with uniform growth and use a manual sprayer for foliar spray treatment, and spray the same amount of water for the control. 24 hours later, the patho...

Abstract

The invention belongs to the technical field of agricultural germicide and in particular relates to a germicide composition containing cyazofamid and thioaminoformate germicide which are formulated and the application thereof; the germicide composition contains the cyazofamid and at least one kind of thioaminoformate germicide, the weight ratio of the cyazofamid and the thioaminoformate germicideis 100:1-1:100; the germicide composition is used for preventing diseases caused by pathogenic fungi and is particularly suitable for controlling downy mildew and epidemic disease and the like on melon and fruit and vegetables, has synergistic interaction and has good effect on overcoming and delaying drug resistance of pathogenic bacteria.

Description

technical field [0001] The invention belongs to the technical field of agricultural fungicides, and in particular relates to a bactericidal composition containing cyfamid and thiocarbamate fungicides and its application. Background technique [0002] Cyazofamid (Cyazofamid) chemical name 4-chloro-2-cyano-5-p-methylphenyl-imidazole-1-N, N-dimethylsulfonamide, belongs to imidazole fungicides, is a mitochondrial respiration inhibitor , has an effect on all growth stages of oomycetes, is active against metalaxyl-resistant or sensitive bacteria, has a certain systemic and therapeutic activity, has a long duration of effect, is resistant to rain erosion, and is harmful to crops, humans, and the environment. It is safe, but long-term single use will inevitably make bacteria resistant to it. [0003] Thiocarbamate fungicides include mancozeb (Mancozeb), a complex salt of manganese ethylene bis-dithiocarbamate and zinc; Zineb, chemical name ethylene bis-disulfide Zinc carbamate; Me...
