Leander 750 EC

Active Ingredient:
• Fenpropidin 750 g/L

Mode of Action:

• Systemic Action: The product is absorbed by the plant and translocated upward through the xylem, protecting both the treated area and upper parts of the plant.
• Inhibition of Ergosterol Biosynthesis: Fenpropidin disrupts the synthesis of ergosterol, a key component of fungal cell membranes, through a mechanism different from that of azole fungicides.
• High Efficacy: The protection period after application is approximately 14 days, depending on local conditions.

Usage Instructions:

• Application:
  • A maximum of two treatments per season is recommended, with a minimum interval of 14 days between applications.
  • The first treatment is applied at the BBCH stage 30-39 (from the onset of ear emergence until the flag leaf appears), while the second treatment is applied at BBCH stage 39-59 (after full development of the flag leaf until the end of ear formation).
  • Use a spray volume of 200–400 L/ha.
• Compatibility:
  • Leander 750 EC is generally compatible with many plant protection products, except those with strongly alkaline reactions. It is advised to perform a compatibility test on a small area before mixing.

Pre-harvest Interval:

• The protection duration is about 14 days, subject to local conditions.
