Problems solved by technology

[0004] The fungicidal composition has poor control effect or easy to produce resistance when the disease occurs, and the active ingredients of the drug are decomposed more due to the increase of light and temperature during storage and transportation, so that the actual dosage often needs to be increased. Thereby increasing the composition and exacerbating environmental pollution

Embodiment 1

[0023] The formulation of 24% Cyazofamida pyraclostrobin suspension concentrate is as follows:

[0024]

[0025] Mix the active ingredient, anti-decomposition factor, wetting and dispersing agent, thickener, carrier and water according to the proportion of the formula, and then grind and / or high-speed shear to obtain 24% Cyazofamid Pyrazole Ether Strobecillin suspension. Used in field trials of grape downy mildew.

[0026] Test method: Dilute 24% Cyazofamida pyraclostrobin suspension concentrate 2500 times with water and spray. The two control agents were used in the same way, and the dilution concentration was 2000 times of 15% Cyazofamid Suspension Concentrate and 2000 times of 250 g / L pyraclostrobin EC. 7 days and 15 days after treatment, the control effect was investigated respectively.

[0027] Test results: The control effects of 24% Cyazofamida pyraclostrobin suspension concentrate were 89.6% and 88.2% 7 days and 15 days after application. The control effects of ...

Embodiment 2

[0029] 30% Cyazofamid Fluazinam Suspension Concentrate

[0030]

[0031]

[0032] Mix the active ingredient, anti-decomposition factor, wetting and dispersing agent, thickener, carrier and water according to the ratio of the formula, and grind and / or high-speed shear to obtain 30% Cyazofamid Fluazinam suspending agent. Used in field trials of grape downy mildew.

[0033] Test method: Dilute and spray 30% Cyazofamid · Fluazinam Suspension Concentrate by 15 g / mu with water, and use the same method for two contrast agents, the dilution concentration is 2000 times and 500 g / mu respectively for 15% Cyazofamid Suspension Concentrate. 30 ml / mu of fluazinam suspending agent was used, and the control effect was investigated 7 days and 15 days after the application.

[0034] Test results: the control effect of 30% Cyazofamid · Fluazinam suspension was 87.2% and 86.2% after 7 days and 15 days after treatment, and the control effect of 15% Cyazofamid Suspension and 500 g / L fluazin...

Embodiment 3

[0036] 60% Cyanozole Cymoxanil Water Dispersible Granules

[0037]

[0038] The active ingredient, anti-decomposition factor, wetting agent and filler are uniformly mixed according to the ratio of the formula, crushed into a wettable powder by airflow, and then a certain amount of water is added to mix and extrude the material. After drying and sieving, a 60% water-dispersible granule of Cyazofamida Cymoxanil was obtained. Used in field trials of tomato late blight.

[0039] Test method: Dilute and spray 60% Cyazofamid·Cymoxanil water dispersible granules 5000 times with water, use the same method as the control agent, the dilution concentration is 2000 times of 20% Cyazofamid water dispersible granules, 20% cream Urea cyanide water dispersible granules 1000 times. 7 days and 15 days after treatment, the control effect was investigated respectively.

[0040] Test results: the control effects of 60% Cyazofamid·cymoxanil water-dispersible granules were 97.9% and 97.5% 7 da...

Abstract

The invention relates to a bactericidal composition containing cyazofamid, which comprises a decomposition-resisting factor and a component C, wherein a mass ratio of a component A, namely the cyazofamid to the decomposition-resisting factor to the component C is (3-50):(0.1-5):(3-60). The bactericidal composition is compounded by multiple active components, a matching ratio of the active components is adjusted, and a stabilizing agent is added, so that the compounded bactericidal composition has a more excellent control effect on an oomycetes disease; action mechanisms of the active components in the bactericidal composition are different, so that pesticide toxicity resistance generation can be avoided, and a generation speed of disease pesticide resistance can be postponed; the bactericidal composition can prevent and expand a bactericidal spectrum, can greatly reduce the pesticide consumption and the use cost, is safer to crops, and can reduce environmental pollution.

Description

technical field [0001] The invention relates to a bactericidal composition containing Cyazofamid, which belongs to the field of pesticide preparation. Background technique [0002] For a long time, due to reasons such as single medicine and medicine being decomposed during storage, the scope of control is too narrow or the control effect is not ideal, and the disease cannot be effectively controlled. In order to effectively kill bacteria, farmers need to frequently apply medicine and constantly change the medicine Varieties, dosages and frequency of medications have all increased significantly, which has increased farmers' planting costs and environmental pollution. [0003] Cyazofamid is commonly used in English as Cyazofamid, and its chemical name is 4-chloro-2-cyano-5-p-methylphenyl-imidazole-1-N, N-dimethylsulfonamide. It is developed and produced by Japan Ishihara Sangyo Co., Ltd. A mitochondrial respiration inhibitor that acts on the Qi site in cytochrome bcl. Cyazof...
