Overview
Difenoconazole technical powder is a high-purity form of the triazole fungicide difenoconazole, used as an active ingredient in agricultural formulations. It belongs to the sterol demethylation inhibitor (DMI) class, which disrupts fungal cell membrane synthesis. Developed for its systemic and protective action, it is effective against a wide range of pathogens, including rusts, powdery mildews, and leaf spot diseases. The compound is favored for its dual protective and curative properties, making it a versatile tool in integrated pest management (IPM) programs. Its stability and efficacy under varying environmental conditions contribute to its widespread adoption in both conventional and organic farming systems, where permitted.
Physical and Chemical Properties
Difenoconazole technical powder appears as a white to off-white crystalline solid with a mild characteristic odor. It has low volatility and is stable under normal storage conditions. The compound is slightly soluble in water (3.3 mg/L at 20°C) but readily dissolves in polar organic solvents such as methanol, acetone, and dichloromethane. Its chemical structure includes a triazole ring and a dioxolane group, which contribute to its systemic mobility within plants. The melting point range of 78-80°C indicates its purity, while the molecular weight of 406.26 g/mol reflects its moderate size for a fungicidal compound. These properties influence its formulation into emulsifiable concentrates, wettable powders, and suspension concentrates.
Main Applications
Difenoconazole is primarily used to control fungal diseases in a variety of crops, including cereals (wheat, barley), fruits (apples, grapes), vegetables (tomatoes, cucumbers), and ornamental plants. It is effective against pathogens such as Septoria, Venturia, and Erysiphe species. The fungicide is typically applied as a foliar spray, with application rates varying by crop and disease pressure. In addition to agricultural uses, difenoconazole is employed in seed treatment to protect against soil-borne and seed-borne pathogens. Its systemic action ensures long-lasting protection during critical growth stages. Recent developments include its combination with other fungicides to broaden the spectrum of activity and delay resistance development in target pathogens.
Safety and Storage
Difenoconazole technical powder is classified as harmful if swallowed, inhaled, or absorbed through the skin. Proper personal protective equipment (PPE), including gloves, goggles, and respirators, should be worn during handling. The compound is not considered highly flammable but should be stored away from heat sources and open flames. Storage recommendations include keeping the product in its original, tightly sealed container in a cool, dry, and well-ventilated area. It should be segregated from food, feed, and incompatible materials such as strong oxidizers. Spills should be contained and cleaned up immediately using inert absorbents, with waste disposed of according to local hazardous material regulations.
B2B Procurement Guide
When procuring difenoconazole technical powder, buyers should verify the supplier's certifications, including ISO and Good Manufacturing Practice (GMP) compliance. Key documentation includes the Material Safety Data Sheet (MSDS), Certificate of Analysis (COA) specifying purity (typically 95-98%), and batch-specific test reports. Quality parameters to assess include impurity profiles, moisture content, and particle size distribution. Bulk purchases (25 kg drums or larger) generally offer better pricing, but ensure proper storage capacity. Lead times may vary seasonally due to agricultural demand cycles. Consider working with suppliers who offer technical support and can provide formulation advice for specific crop applications.
