Product Introduction
Cyprodinil + Fludioxonil 62.5% WDG is a high-performance water-dispersible granule fungicide combining two complementary active ingredients. Cyprodinil (37%) belongs to the anilinopyrimidine chemical class, while Fludioxonil (25%) is a phenylpyrrole fungicide. This unique combination provides dual-mode action against a wide range of fungal diseases, offering protective, curative, and anti-sporulant activity.
With excellent adhesion and rainfastness, this formulation is ideal for both seed treatment and foliar application, delivering reliable disease control in integrated crop management programs.
The WDG formulation ensures:
- Easy handling and measuring
- Rapid dispersion in water
- Low dust and excellent tank-mix compatibility

Mode of Action
This product combines two distinct modes of action:
- Cyprodinil – inhibits methionine biosynthesis, disrupting protein synthesis and fungal growth.
- Fludioxonil – disrupts osmotic signal transduction, leading to uncontrolled fungal cell growth.
Key characteristics:
- Dual-site action → low resistance risk
- Broad-spectrum activity
- Long-lasting residual control
- Effective on seed and foliar diseases
