Description

Probenazole CAS NO 27605-76-1 is a systemic plant activator and fungicide belonging to the benzisothiazole chemical class. This compound is valued for its unique mode of action, which induces systemic acquired resistance (SAR) in plants, enhancing their natural defense mechanisms against a broad spectrum of pathogens. It is primarily utilized in the agricultural and horticultural sectors for the protection of key crops such as rice, vegetables, and fruits from fungal and bacterial diseases.

Application

• Rice Blast Control: A cornerstone application for protecting rice crops against the devastating rice blast fungus (*Magnaporthe grisea*).
• Systemic Plant Defense Activator: Used to trigger systemic acquired resistance (SAR) in various crops, priming them against subsequent pathogen attacks.
• Vegetable and Fruit Disease Management: Applied for controlling bacterial and fungal diseases in high-value crops including tomatoes, cucumbers, and peppers.
• Seed Treatment: Employed as a protective seed treatment to safeguard seedlings from soil-borne pathogens during early growth stages.
• Integrated Pest Management (IPM) Programs: A key component in sustainable agriculture strategies to reduce reliance on conventional fungicides and manage resistance.
• Agricultural Formulations: Serves as the active technical ingredient in the manufacture of wettable powders (WP), suspension concentrates (SC), and other commercial fungicide formulations.
