سفارشات

نامیاتی کنٹرول

Remove infected shoots. After an infection, use a plant fortifier, so the plants are able to fight the fungi. You can choose more resilient varieties, such as Glen Moy, Glen Rosa, Julia, Malling Admiral or Leo.

کیمیائی کنٹرول

Fungicides based on Lime Sulfur or Captan/Fenhexamid mixtures can be used.

یہ کس وجہ سے ہوا

The pathogen enters the plant with humid spring weather and hibernates in the affected shoots.

احتیاطی تدابیر

  • Balanced nutrition supply is important. Injuries should be avoided. Leave sufficient distance between plants. Apply plant fortifier۔
