Overview
Pyraclostrobin Technical is a highly effective fungicide belonging to the strobilurin class. It is widely used in agriculture to protect crops from a variety of fungal pathogens. The compound works by inhibiting mitochondrial respiration in fungi, leading to their death. Its broad-spectrum activity makes it a popular choice among farmers and agricultural professionals. Pyraclostrobin is known for its systemic and protectant properties, meaning it can be absorbed by plants and provide long-lasting protection. It is commonly applied as a foliar spray or seed treatment, depending on the crop and disease being targeted. The chemical is favored for its ability to enhance crop yield and quality by preventing yield losses due to fungal infections.
Physical and Chemical Properties
Pyraclostrobin Technical appears as a white to light beige crystalline powder with a melting point range of 63-68°C. It is slightly soluble in water but dissolves well in organic solvents such as acetone and methanol. The molecular formula is C19H18ClN3O4, with a molecular weight of 387.82 g/mol. The compound is stable under normal storage conditions but should be kept away from direct sunlight and moisture to prevent degradation. Its chemical stability ensures long shelf life when stored properly. Pyraclostrobin's low water solubility reduces the risk of leaching into groundwater, making it environmentally favorable compared to some other fungicides.
Main Applications
Pyraclostrobin Technical is primarily used in agriculture to control fungal diseases in a wide range of crops. It is effective against pathogens causing powdery mildew, rust, leaf spot, and blight in cereals, fruits, and vegetables. The fungicide is often applied as a foliar spray, providing both protective and curative effects. In addition to its fungicidal properties, Pyraclostrobin has been shown to improve plant health by enhancing photosynthetic efficiency and stress tolerance. This makes it a valuable tool for integrated pest management (IPM) programs. Its versatility and efficacy have led to its adoption in both conventional and organic farming systems, where it is used in combination with other agrochemicals to maximize crop protection.
Safety and Storage
Pyraclostrobin Technical should be handled with care to minimize exposure. Workers must wear appropriate personal protective equipment (PPE), including gloves, goggles, and respiratory protection, when handling the chemical. Avoid inhalation, ingestion, and direct contact with skin or eyes. Storage conditions are critical to maintaining the product's efficacy. It should be kept in a cool, dry place, away from direct sunlight and moisture. The chemical should be stored in its original container, tightly sealed, and away from food, feed, and beverages. In case of spills, contain the material and dispose of it according to local regulations to prevent environmental contamination.
B2B Procurement Guide
When procuring Pyraclostrobin Technical, B2B buyers should verify the CAS number (175013-18-0) and purity specifications to ensure product authenticity. It is advisable to source from reputable suppliers who comply with local and international regulatory standards. Price ranges typically vary between $50-$100 per kg, depending on purity, quantity, and supplier. Buyers should also consider logistics, including shipping and storage requirements, to maintain product integrity. Bulk purchases may offer cost savings, but storage capacity and shelf life should be factored into procurement decisions. Always request material safety data sheets (MSDS) and certificates of analysis (CoA) for quality assurance.
