Sphinx Extra

Double Strike Against Pathogens: How Sphinx Extra Works

Effective protection for vineyards and potatoes depends on a fungicide's ability to block fungal development at multiple stages. Sphinx Extra from ADAMA utilizes a powerful combination of systemic and contact active ingredients to overcome pathogen resistance and provide comprehensive crop safety.

Synergy of Active Ingredients

The product relies on two primary components: dimethomorph and folpet. This duality makes the fungicide a versatile tool against diverse fungal threats:

• Dimethomorph (Systemic action): Absorbed by plant tissues, it inhibits cellulose biosynthesis in fungal cell walls. This is essential for controlling downy mildew in vineyards and late blight in potatoes. It acts on the pathogen throughout its life cycle, specifically targeting sporulation.
• Folpet (Contact action): Establishes a protective barrier on the leaf and stem surfaces. The phthalimide group disrupts the metabolic processes of the pathogen, effectively preventing spore germination.

Field-Proven Advantages

The main technological benefit of Sphinx Extra is the interplay between the two mechanisms. While the systemic component works from within to neutralize latent infections, the contact folpet prevents new spores from colonizing the surface. The water-dispersible granule (WDG) formulation ensures optimal tank-mix stability without dusting or measuring inconsistencies.

Application and Best Practices

Sphinx Extra ensures high efficacy when used according to strict protocols:

• Maximum Treatments: Up to 3 applications per season.
• Safety Profile: Classified as Hazard Class 3, compliant with professional crop protection standards.
• Pre-harvest Interval (PHI): 20–30 days, allowing for efficient harvest planning.
• Dosage: Typically exceeding 4.0 kg/ha, depending on the severity of the infection and the crop type.

Applying this product enables growers to not only stop active outbreaks but also maintain a long-lasting preventive effect, which is critical during high-humidity periods when late blight or downy mildew can spread rapidly.
