Our product, High Quality Pyraclostrobin CAS 175013-18-0 With Good Price, is a highly effective fungicide. Its CAS number, 175013-18-0, uniquely identifies it in the chemical industry. Pyraclostrobin belongs to the strobilurin class of fungicides, which are known for their broad - spectrum activity and excellent preventive and curative properties.
The chemical formula of pyraclostrobin is C19H18ClN3O4. It has a molecular weight of approximately 387.82 g/mol. The product is usually presented as a white to light - yellow solid powder with a melting point ranging from 63 - 65°C. It has a low solubility in water but is soluble in some organic solvents such as acetone, methanol, and dichloromethane.
Pyraclostrobin is widely used in agriculture to control a variety of fungal diseases. It has a broad - spectrum activity against many pathogenic fungi, including Ascomycetes, Basidiomycetes, and Deuteromycetes. Some of the common diseases it can control include powdery mildew, rust, leaf spot, and blight in a wide range of crops such as cereals (wheat, barley, rice), fruits (apples, grapes), and vegetables (tomatoes, cucumbers).
In addition to its fungicidal activity, pyraclostrobin can also enhance plant health. It improves photosynthesis, increases nutrient uptake, and enhances the plant's resistance to stress conditions such as drought and heat. This leads to better crop yields, improved quality of produce, and longer shelf - life of harvested products.
Before using pyraclostrobin, it is important to read the label instructions carefully. The product can be applied as a foliar spray, seed treatment, or soil drench, depending on the target crop and disease.
For foliar spray applications, mix the appropriate amount of pyraclostrobin with water in a spray tank. The dosage rate depends on the crop, the severity of the disease, and the application method. It is usually recommended to start with a lower dosage and increase it if necessary. Make sure to spray the solution evenly on the leaves, covering both the upper and lower surfaces.
When using it as a seed treatment, coat the seeds with the pyraclostrobin formulation according to the recommended rate. This helps protect the seedlings from soil - borne diseases during the early growth stages.
For soil drench applications, apply the diluted pyraclostrobin solution to the soil around the base of the plants. This method is effective for controlling root - infecting fungi.
Case 1: Wheat Crop
In a wheat field in a region prone to rust diseases, pyraclostrobin was applied as a foliar spray at the recommended rate during the tillering and booting stages. Before the application, the rust disease had started to spread, causing yellowish - orange pustules on the leaves and reducing the photosynthetic area. After the application of pyraclostrobin, the spread of the rust was effectively controlled. The treated wheat plants showed less disease symptoms, and the leaves remained green and healthy for a longer period. As a result, the yield of the wheat crop increased by approximately 20% compared to the untreated control field.
Case 2: Grapevine
A grapevine orchard was suffering from powdery mildew, which was affecting the quality and quantity of the grapes. Pyraclostrobin was used as a foliar spray at regular intervals during the growing season. The treatment not only controlled the powdery mildew but also improved the overall health of the grapevines. The grapes from the treated vines were larger, had better color, and higher sugar content. The wine produced from these grapes also had a better flavor profile, leading to higher market value.
