Direct supply of high-purity technical grade actives and advanced crop protection solutions from certified Chinese manufacturing facilities.
An in-depth evaluation of global sourcing patterns, resistance management strategies, and China's dominance in broad-spectrum fungicide manufacturing.
Cyprodinil (CAS No. 121552-61-2) has emerged as a cornerstone active ingredient in global integrated pest management (IPM) programs. As a high-efficiency anilino-pyrimidine fungicide, it exhibits exceptional preventative and curative control against key fungal pathogens, particularly Botrytis cinerea (gray mold), Venturia inaequalis (apple scab), and Monilinia spp. in high-value horticulture.
International agricultural buyers—spanning North America, the European Union, Latin America, and Southeast Asia—increasingly rely on China cyprodinil pesticide factories and manufacturers for reliable scale, cost-competitive technical grade (TC) material, and customized water-dispersible granule (WDG) formulations.
Driven by strict environmental compliance standards and vertical integration, leading Chinese agrochemical enterprises have optimized the synthesis of cyprodinil. Local manufacturers provide:
Understanding how Cyprodinil disrupts fungal cell metabolism at the molecular level to deliver long-lasting crop protection.
Cyprodinil belongs to the FRAC Group 9 (Anilino-pyrimidines). Its targeted mode of action involves inhibiting the biosynthesis of methionine, an essential amino acid required for fungal fungal growth and tissue penetration. By interfering with cystathionine beta-lyase, it arrests germ tube elongation and mycelial growth instantly.
Once applied to plant foliage, Cyprodinil demonstrates rapid acropetal (upward) systemic redistribution through xylem tissues, as well as translaminar movement across leaf surfaces. This guarantees total coverage, protecting newly emerging tissue and untreated underside leaves against rain-washout.
To widen the antimicrobial spectrum and combat single-site mutation risks, Chinese chemical producers excel at formulating dual-action blends. Combining Cyprodinil (methionine inhibitor) with Fludioxonil (osmotic signal transduction inhibitor) provides dual-site protection against Botrytis with zero cross-resistance.
Primary Target Pathogens: Botrytis cinerea (Gray Mold), Venturia inaequalis (Apple Scab), Monilinia fructicola (Brown Rot), Blumeria graminis (Powdery Mildew in Cereals), and Pyrenophora teres (Net Blotch).
Key Crops: Table & Wine Grapes, Pome Fruit (Apples, Pears), Stone Fruit (Peaches, Plums), Strawberries, Blueberries, Tomatoes, Cucurbits, and Small Grain Cereals.
Rigorous analytical testing according to FAO/WHO specifications ensures optimal batch-to-batch consistency and international compliance.

Delivering high-performance agrochemical solutions, tailored supply chain support, and rigorous regulatory compliance worldwide since 2006.
Awiner Biotech was founded in 2006, located in the northern chemical manufacturing heartland of Shijiazhuang, Hebei Province, China. Positioned in close proximity to the national capital Beijing, our facility benefits from robust multimodal transportation logistics, direct railway corridors, and fast access to Tianjin Port for efficient global export dispatch.
Awiner Biotech specializes in the comprehensive research, synthesis, formulation development, and international distribution of a broad range of agricultural chemicals. Our core focus spans advanced fungicides (such as Cyprodinil, Metalaxyl, Mancozeb, and Tricyclazole), high-potency insecticides, broad-spectrum herbicides, biological pest controls, and precision plant growth regulators.
Up to now, Awiner Biotech has successfully established strong commercial partnerships and secured product registrations across more than 30 nations worldwide, including:
Active Footprint: Iraq, Iran, Afghanistan, Pakistan, India, Libya, Syria, Turkey, Yemen, Ukraine, Russia, Kazakhstan, Uzbekistan, Chile, Bolivia, Mexico, Brazil, Paraguay, Nigeria, Djibouti, Rwanda, Somalia, Malaysia, Cambodia, Nepal, Myanmar, and beyond.
Our commitment extends far beyond direct exports. We regularly participate in international agrochemical exhibitions in Turkey, Iran, Pakistan, Nigeria, Russia, Cambodia, Malaysia, and Uzbekistan. Furthermore, our agronomists perform hands-on customer market surveys—visiting client fields directly to inspect crop performance, analyze regional disease strains, optimize spray timing, and resolve localized resistance issues.
