Product Specifications

Key Benefits of Contras Plus

• Systemic Action: Hexaconazole is absorbed into treated plant tissues to suppress susceptible fungal infections.
• Preventive Protection: Helps protect crops when applied before or during the early stages of fungal disease development.
• Early Curative Activity: Restricts the development of susceptible fungal pathogens after initial infection.
• Powdery Mildew Management: Recommended for powdery mildew in grapes and mango.
• Rice Sheath Blight Management: Helps manage sheath blight in paddy.
• SC Formulation: Designed for dilution in water and uniform foliar application.

How Does Contras Plus Work?

Hexaconazole is a systemic triazole fungicide belonging to FRAC Group 3. It inhibits sterol 14-alpha-demethylase, an enzyme involved in the biosynthesis of ergosterol, which is essential for normal fungal cell membrane development.

By interfering with ergosterol production, Hexaconazole restricts the growth and development of susceptible fungal pathogens. Its systemic movement within treated tissues supports preventive and early curative disease management.

Recommended Crops, Diseases and Dosage

Silver Sine provides the following recommendations for Contras Plus on its official product page.

Dosage Note: These values are published by the manufacturer. Verify the current registered product label for approved crop uses, application rates, total spray volume, treatment intervals and pre-harvest waiting periods.

Application Method

Measure the label-recommended quantity of Contras Plus for the target crop and disease. Add it to a partially filled spray tank containing clean water, mix thoroughly and complete the dilution as directed.

Apply uniformly to the recommended crop surfaces using suitable spraying equipment. Avoid spraying during strong winds, rainfall or other unsuitable weather conditions.

When Should You Use Contras Plus?

Contras Plus is primarily used for preventive and early-stage management of susceptible fungal diseases. Regular crop monitoring helps identify powdery mildew or sheath blight symptoms and determine suitable application timing.

Because Hexaconazole belongs to FRAC Group 3, avoid unnecessary repeated applications of fungicides from the same group. Follow registered fungicide rotation and resistance management recommendations.
