Description

Meclozolin CAS NO 54864-61-8 is a selective fungicide belonging to the chemical class of oxazolidinones. It matters for its specific activity against a range of plant-pathogenic fungi, particularly those affecting fruits and vegetables. This product is needed by agricultural chemical formulators and crop protection specialists for developing effective fungicidal solutions.

Application

• Primary use as a fungicide in agricultural crop protection programs.
• Formulation into wettable powders (WP), suspension concentrates (SC), or emulsifiable concentrates (EC) for foliar application.
• Control of powdery mildew, scab, and other fungal diseases in pome fruits (e.g., apples, pears).
• Protection of vegetable crops, including cucurbits and solanaceous plants, from key fungal pathogens.
• Use in integrated pest management (IPM) strategies due to its selective mode of action.
• Potential for use in seed treatment formulations to protect against soil-borne and seed-borne diseases.
• Research and development of new agrochemical formulations and mixtures.
