ट्रिगर

Anthracnose is caused by a fungus that hibernates on fallen leaves. In spring, spores grow on the old leaves and are carried by the wind to the young leaves, where they cause a new infection. In humid climates, the fungus forms new spores on the infected leaves. These help to spread the fungal spores and with them, the disease.

जैविक नियंत्रण

When you notice first spots, cut the affected leaves.

रासायनिक नियंत्रण

Always consider an integrated approach with preventive measures together with biological treatments if available. Fungicides of the strobilurins family, or those based on copper, fluazinam, pyraclostrobin or cyprodinil and fludioxonil can be applied.

निवारक उपाय

  • Remove infected leaves before spring. Prune the bushes for good ventilation. Mulching is highly recommended. Apply fertilizer to strengthen plants. Plant resilient varieties like the “Rovada” currant, and the “Invicta”, “Mucurines”, or “Reflamba” gooseberry.
