Description

Procymidone is a systemic fungicide belonging to the dicarboximide chemical class, valued for its broad-spectrum activity against a range of fungal pathogens. Its primary commercial value lies in providing effective, targeted control of botrytis and sclerotinia diseases, which are major threats to crop yield and quality. This product is essential for agricultural professionals and formulators in the crop protection industry seeking reliable disease management solutions for fruits, vegetables, and ornamental plants.

Application

• Botrytis Cinerea Control: Primary application for protecting grapes (against Botrytis bunch rot), strawberries, tomatoes, and other soft fruits from gray mold.
• Sclerotinia Sclerotiorum Management: Effective against white mold in crops such as oilseed rape (canola), beans, lettuce, and sunflowers.
• Fruit & Vegetable Protection: Used on a variety of crops including stone fruits, cucurbits, and onions to control key fungal diseases during pre- and post-harvest stages.
• Ornamental Plant Disease Control: Applied in greenhouse and nursery settings to manage blights and rots in ornamental plants and flowers.
• Agricultural Formulations: Serves as a key active ingredient in the manufacturing of wettable powders (WP), suspension concentrates (SC), and other commercial fungicide formulations.
• Post-Harvest Treatment: Used in some registered applications to extend the shelf-life of produce by preventing fungal decay during storage and transport.

Quality Control

Our Procymidone technical material is manufactured under a strict quality management system to ensure batch-to-batch consistency and efficacy. Quality is verified through comprehensive analytical testing, including assay by HPLC, identification by IR spectroscopy, and control of key impurities. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee compliance with industry and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect stability and performance. Keep away from heat, sparks, and open flame.
