Applications
A. Control of Oomycete Diseases
Cyazofamid丨CAS 120116-88-3 is primarily used to control oomycete pathogens, particularly:
Phytophthora infestans - causing late blight in potatoes and tomatoes
Plasmopara viticola - causing downy mildew in grapes
Other downy mildew species affecting cucurbits, lettuce, and ornamentals
Its high specificity against oomycetes with minimal activity on other fungi makes it a valuable selective fungicide.
B. Crop Usage
Potatoes and Tomatoes: Controls late blight, a devastating disease causing major yield losses.
Grapes: Protects against downy mildew, important for wine quality and yield.
Vegetables: Used on cucurbits (cucumbers, melons) and leafy greens to manage downy mildew.
Ornamentals: Controls diseases in greenhouse and landscape settings.
Benefits
A. Unique Mode of Action
Cyazofamid targets a novel binding site in the mitochondrial electron transport chain, differing from traditional QoI fungicides.
This novel action delays resistance development, making it a useful rotation partner.
B. Effective at Low Use Rates
Highly potent at low application doses, reducing overall chemical load.
Provides rapid and long-lasting disease control.
C. Systemic and Protective Action
Penetrates plant tissues to provide both protective and curative effects.
Protects new growth and prevents pathogen spread.
D. Resistance Management
Used in integrated resistance management programs due to its unique mode of action.
Typically rotated with fungicides from different FRAC groups to minimize resistance risk.
E. Environmental and Human Safety
Exhibits low toxicity to mammals, birds, and beneficial insects.
Rapid degradation in the environment limits persistence.
Conclusion
Cyazofamid丨CAS 120116-88-3 is an advanced, selective fungicide that effectively controls economically significant oomycete diseases such as late blight and downy mildew. Its novel mode of action and strong efficacy at low doses make it an important component of integrated disease management programs. Cyazofamid's favorable safety and environmental profile further enhance its value for sustainable agricultural practices. Proper use and resistance management will ensure its continued effectiveness in protecting crops worldwide.
