Cyprodinil (CAS No. 121552-61-2) is a broad-spectrum, systemic fungicide belonging to the anilinopyrimidine class. Its primary mechanism involves the inhibition of methionine biosynthesis within fungal pathogens. By disrupting the secretion of fungal enzymes necessary for tissue penetration, Cyprodinil effectively stops the infection cycle during germ tube elongation and mycelial growth.
Unlike triazoles or strobilurins, Cyprodinil exhibits exceptional efficacy under cooler weather conditions (5°C to 15°C), making it an essential crop protection asset during early spring infections such as Botrytis cinerea (gray mold) and Venturia inaequalis (apple scab).
Modern global agriculture is transitioning away from Wettable Powders (WP) and Emulsifiable Concentrates (EC) due to inhalation safety hazards and organic solvent emissions. Cyprodinil 50% WDG represents the gold standard in dry flowable technology:
Why Tier-1 global distributors and multinational ag-chem companies source Cyprodinil formulations from Chinese industrial hubs.
China commands over 75% of global capacity for intermediate compounds such as 2-amino-4-chloro-6-methylpyrimidine. Chinese synthesis hubs in Hebei, Jiangsu, and Shandong benefit from fully integrated supply chains—from crude petrochemical feedstocks down to finished 50% WDG formulations. This vertical integration guarantees price resilience and batch-to-batch consistency.
Leading Chinese pesticide plants operate under stringent environmental protection protocols. Equipped with advanced regenerative thermal oxidizers (RTO) and biological wastewater treatment systems, tier-1 suppliers guarantee uninterruptible manufacturing cycles despite regulatory audits, insulating overseas buyers against supply chain shocks.
Industry R&D in China has shifted aggressively toward ultra-fine milling and modern micro-granulation. Chinese Cyprodinil 50% WDG products utilize specialized fluid bed granulation towers, ensuring uniform particle size distribution (2-5 microns), zero dust generation, and prolonged thermal stability under tropical export conditions.
When requesting quotes for Cyprodinil 50% WDG from Chinese manufacturers, always verify technical active purity (TC grade ≥ 98%), suspensibility testing parameters (FAO standards specify ≥ 80%), and wet sieve residue (< 0.5% on 75μm sieve). High-grade WDG granules maintain full suspendability even in hard water environments (up to 342 ppm CaCO3 equivalent).

Addressing core technical, regulatory, and commercial procurement inquiries from enterprise buyers.
Our standard Minimum Order Quantity (MOQ) for custom-packaged Cyprodinil 50% WDG is 500 kg. For customized aluminum foil packaging with private label printing, the MOQ is 1,000 kg due to specialized printing run requirements. Bulk drum packaging can be supplied for smaller trial orders upon negotiation.
Cyprodinil excels in cool weather applications (5°C to 15°C) where systemic uptake of triazole and strobilurin fungicides drops significantly. Its ability to penetrate plant cuticles under low ambient thermal conditions makes it ideal for early-spring apple scab and grapevine botrytis preventive sprays.
Yes, Cyprodinil 50% WDG is physical and chemical compatible with most standard fungicides, insecticides, and plant growth regulators. It is commonly tank-mixed or co-formulated with Fludioxonil, Azoxystrobin, or Difenoconazole. However, tank mixing with highly alkaline materials (such as Bordeaux mixture or lime sulfur) should be avoided to prevent chemical degradation.
We provide full regulatory support packages including Certificate of Analysis (COA), Safety Data Sheets (MSDS), ICAMA factory registration certificates, 5-batch analysis reports, and letter of authorization (LOA) for official product registration in your destination country.
Cyprodinil 50% WDG has a shelf life of 2 years when stored in its original unopened packaging in a cool, dry, and well-ventilated warehouse away from direct sunlight, moisture, and extreme heat sources (above 35°C).
