How to treat?

  • microscopeBiological

    • If possible remove and destroy the infected plant. Burn it, toss it into the garbage, or bury it deeply. Do not compost.

    • For woody plants: rake the fallen leaves. Prune off and destroy infected parts of the plant.

    • Apply ecological products for plant protection (e.g. copper-based spray).

  • pillChemical

    • If necessary, apply fungicide containing chlorothalonil (GHS05: Corrosive, GHS06: Toxic, GHS07: Harmful, GHS08: Health hazard, GHS09: Environmental hazard).

    • If necessary, apply fungicide containing captan (GHS05: Corrosive, GHS06: Toxic, GHS07: Harmful, GHS08: Health hazard, GHS09: Environmental hazard).

  • syringeDisease prevention

    • Use resistant species and cultivars as well as healthy, certified seeds and seedlings.

    • Prune the plant. Pruning will increase airflow and the amount of light.

    • Rotate crops. Avoid planting sensitive crops in infested soil.

    • Keep the moisture low, avoid prolonged wetting of the leaves (e.g. by overhead irrigation) and ensure good soil drainage.

    • Disinfect tools, infected flower pots, and hands to avoid disease transmission.
