Propiconazole 250g/L + Cyproconazole 80g/L EC is an advanced emulsifiable concentrate fungicide developed to provide broad-spectrum disease control in modern crop protection programs.
Both active ingredients belong to the Triazole chemical class and work systemically within the plant, delivering reliable results against a wide range of fungal pathogens.
Dual-Active Combination for Broader Spectrum
-
Propiconazole (250g/L) acts by inhibiting ergosterol biosynthesis in fungal cell membranes, disrupting cell development and reproduction.
-
Cyproconazole (80g/L) works through a similar mode of action but binds at slightly different sites in the fungal enzyme system, enhancing overall efficacy and delaying resistance development.
When used together, the two triazoles provide:
-
Strong protective, curative, and eradicant properties for existing infections and newly developing ones.
-
Broadened control spectrum, targeting multiple pathogens in one spray.
-
Better performance under fluctuating disease pressure compared to single active ingredient products.
Emulsifiable Concentrate (EC) Advantages
-
Easy to mix and maintain stable emulsification in the spray tank.
-
Ensures uniform spray droplet size, leading to better leaf coverage and absorption.
-
Facilitates quick uptake and upward translocation (acropetal movement) for protection throughout the plant canopy.
Physical & Storage Stability
-
Clear to slightly yellowish liquid, easy to handle and dose.
-
Stable for at least 2 years under recommended storage conditions.
-
Compatible with common adjuvants and fungicide partners for resistance management programs.
Where It Fits in the Field
Propiconazole 250g/L + Cyproconazole 80g/L EC is widely used in:
-
Cereal crops (wheat, barley) for rusts, leaf spots, and powdery mildew.
-
Fruit trees (apples, pears, citrus) for scab, powdery mildew, and other foliar diseases.
-
Grapes and vegetables where powdery mildew and leaf spots threaten crop health and market quality.
Its systemic action, combined with protective and curative properties, makes it an excellent fit for integrated spray programs where disease prevention and resistance management are priorities.
Mode of Action
Propiconazole 250g/L + Cyproconazole 80g/L EC works through a systemic, protective, curative, and eradicant mode of action.
Both active ingredients belong to the Triazole (DMI, Demethylation Inhibitor) class of fungicides, which act by interfering with the biosynthesis of ergosterol, a vital component of fungal cell membranes.
How Propiconazole Works
Propiconazole enters the plant tissues quickly after foliar application.
It moves primarily acropetally (upward through the xylem) to reach growing points where new infections are most likely to occur.
Inside the fungus, it blocks the demethylation step in sterol biosynthesis, leading to defective cell membranes.
This disruption halts the growth and spread of the pathogen, providing both curative and protective effects.
How Cyproconazole Works
Cyproconazole acts in a similar way but has slightly different binding affinity and activity spectrum compared to Propiconazole.
It also inhibits ergosterol synthesis, but due to its molecular structure, it can bind to alternative sites within the fungal enzyme system.
This subtle difference helps broaden the spectrum of control and slows down the development of resistant fungal strains.
Synergistic Performance
When combined, Propiconazole and Cyproconazole:
-
Deliver strong systemic movement within the plant, protecting treated foliage and new growth.
-
Provide overlapping but slightly different binding sites in the pathogen’s biochemical pathways, which enhances the overall fungicidal activity.
-
Reduce the risk of resistance buildup by requiring multiple mutation points for fungi to survive.
The result is a fungicide that not only controls current infections but also provides residual protection against reinfection during critical crop growth stages.
