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

[0027] Embodiment 1: Determination of antibacterial activity of Cyazofamid and Zinc monomixture to cabbage downy mildew

[0028] Test method: use greenhouse potted cabbage seedlings to the 2-3 leaf stage, spray the leaves according to the designed dosage, and spray the same amount of water as the control. After 24 hours, cabbage downy mildew was inoculated, cultivated under moisture-retaining conditions, and the results of the survey were investigated when the blank control without pesticide application was fully onset. The test results are shown in Table 2.

[0029] Table 2 Determination of antibacterial activity of Cyazofamid and Zinc monomixture against cabbage downy mildew

[0030]

[0031] It can be seen from Table 2 that the combination of Cyazofamid and Zinc has good indoor antibacterial activity against cabbage downy mildew, which is higher than that of a single agent.

Embodiment 2

[0032] Embodiment 2: Determination of the antibacterial activity of Cyazofamid and mancozeb single mixture to grape downy mildew

[0033] Grape seedlings were cut in the greenhouse to determine the antibacterial effect of Cyazofamid and Mancozeb single mixture on grape downy mildew. When the grape seedlings grow to 3 to 4 leaves, select 2 leaves that grow uniformly, and use a manual sprayer to spray the foliar chemicals, and spray the same amount of water as the control. After 24 hours, the pathogenic bacteria were inoculated, and the investigation results were obtained after culturing for 7 days under moisturizing conditions. The results are shown in Table 3.

[0034] Determination of the antibacterial activity of table 3 Cyazofamid and mancozeb single mixture to grape downy mildew

[0035]

[0036] It can be seen from Table 3 that the combination of Cyazofamid and Mancozeb has good indoor antibacterial activity against P. viticola, and the antibacterial activity is highe...

Embodiment 3

[0037] Embodiment 3: The efficacy test of Cyazofamid and propineb monomixture in the prevention and treatment of tomato late blight

[0038] 74% Cyazofamida Propineb wettable powder comprises the following components by weight:

[0039] Cyazofamida 4%

[0040] Propineb 70%

[0041] Sodium dodecylbenzenesulfonate 2.5%

[0042] White carbon black 10%

[0043] Lignocalcium 4%

[0044] Pull apart powder 3%

[0045] K12 3%

[0046] Light calcium carbonate balance

[0047] The above-mentioned components are fully mixed according to the formula ratio, and after being pulverized by an ultrafine pulverizer, a 74% Cyazofamida Propineb wettable powder can be obtained.

[0048] Tomato seedlings were grown in pots in the greenhouse, and the control effects of Cyazofamid, Prozebine and the above-mentioned mixtures on tomato late blight were determined. When the tomato grows to 3 to 4 leaves, select the leaves with uniform growth and spray the leaves with a manual sprayer, and spray ...
