Our product is Factory Supply Cyprodynil with the CAS number 121552-61-2. Cyprodynil is a fungicide belonging to the anilinopyrimidine class. It has a molecular formula of C₁₅H₁₈N₄ and a molecular weight of approximately 254.33 g/mol. This product is available at a low price, which makes it an economical choice for various applications.
It appears as a white to off - white crystalline powder. It has a melting point of around 75 - 77°C and a vapor pressure of 1.3×10⁻⁵ Pa at 25°C. Cyprodynil is slightly soluble in water, with a solubility of about 1.5 g/L at 25°C, and is soluble in organic solvents such as acetone, methanol, and toluene.
Cyprodynil is widely used in the agricultural industry as a fungicide. It effectively controls a broad spectrum of fungal diseases on a variety of crops. For example, it can be used to prevent and treat diseases on apples, pears, grapes, strawberries, and other fruits. It is particularly effective against Botrytis cinerea (gray mold), Monilinia spp. (brown rot), and Venturia inaequalis (apple scab).
In addition to fruits, it can also be applied to vegetables such as tomatoes, cucumbers, and lettuce to protect them from fungal infections. By using Cyprodynil, farmers can significantly reduce crop losses caused by fungal diseases, thereby increasing the yield and quality of their produce.
Before using Cyprodynil, it is necessary to carefully read the product label and follow the instructions. The application rate depends on the type of crop, the severity of the disease, and the application method.
For foliar spray, typically, a solution with a concentration of 0.1 - 0.2% (w/v) of Cyprodynil is prepared. First, add the appropriate amount of Cyprodynil to a suitable volume of water in a spray tank. Stir well to ensure uniform dissolution. Then, use a sprayer to evenly spray the solution on the leaves of the crops, covering both the upper and lower surfaces. It is recommended to apply the spray in the early morning or late afternoon to avoid high - temperature evaporation and ensure better adhesion to the leaves.
For soil treatment, the product can be mixed with soil or irrigation water. The recommended dosage for soil treatment is usually 1 - 2 kg per hectare. This method can effectively prevent soil - borne fungal diseases and protect the roots of the plants.
Apple Orchard in Shandong, China: An apple orchard in Shandong Province had been suffering from severe apple scab for several years. After using Factory Supply Cyprodynil, the situation was significantly improved. The farmers applied a foliar spray of Cyprodynil at a concentration of 0.15% (w/v) at the early stage of the disease. They repeated the application every 10 - 14 days during the growing season. As a result, the incidence of apple scab was reduced from over 30% in previous years to less than 5% in that year. The quality of the apples also improved, with fewer blemishes and better color. The yield increased by about 20% compared to the previous year, bringing substantial economic benefits to the orchard.
Grape Vineyard in France: In a grape vineyard in France, Botrytis cinerea was a major problem, especially during the rainy season. The vineyard manager decided to use Cyprodynil for prevention. They prepared a 0.2% (w/v) Cyprodynil solution and sprayed it on the grapevines before the onset of the rainy season. The spray was repeated every two weeks. This preventive measure effectively controlled the spread of Botrytis cinerea. The percentage of infected grapes decreased from 20% in previous years to less than 5%. The wine made from these grapes also had a better taste and quality, which was well - received in the market.
