Description

Active Ingredients:
• Captan 360 g/l
• Potassium phosphonates 660 g/l

Mode of Action:

  • Multi-site and partially systemic: Captan rapidly penetrates susceptible fungal spores, inhibiting their germination and the development of the germ tube.
  • Anti-sporulant effect: The product forms a protective film on the plant surface that is difficult to wash off with rain, providing long-lasting protection.
  • Enhancement of plant defense: Potassium phosphonates not only exhibit antifungal activity but also stimulate the plant’s defensive system, offering additional protection.

Usage Instructions (example):

  1. Application:
    • Use as a preventive foliar spray or at the first signs of disease during the growing season.
    • Apply at recommended doses (e.g., 2 L/ha for apple and pear) with water volumes ranging from 300 to 1500 L/ha.
    • Treatments can be repeated every 15 days, with up to 8 applications per season, depending on disease pressure.
  2. Precautions:
    • Follow label instructions for dosage and pre-harvest intervals (e.g., 28 days before harvest).
    • Always perform compatibility tests when tank-mixing with other products.

Advantages:

  • Provides up to 15 days of protection against plant pathogens.
  • Highly effective in controlling scab in apple and pear orchards.
  • Stable formulation that resists wash-off by rain.
