Symptoms
An off-white fungal covering grows on the leaves, fruits and shoot tips of the gooseberry. On currant plants, the leaves of the shoot tips exhibit an off-white fungal covering on the underside that can also extent to the upper side. The results can be early leaf fall and reduced shoot growth.
Recommendations
Organic Control
Cut back infected shoots. Use milk-water solutions, which function as natural fungicides (you can find tips in the main menu - information on plant diseases - preventive plant protection). Apply this solution every other day to the leaves.
Chemical Control
Fungicides with Sulfuric , Difenoconazole and Azoxystrobin can be used.
What caused it?
The fungus spreads on the plant via its spores. In summer, infection rates increase.
Preventive Measures
- Plant more resilient varieties in areas with high occurrence of Powdery Mildew.
- Ensure sufficient distance between the plants to allow for good ventilation.
- Give sufficient light to plants.
- Provide a balanced nutrient supply.
- Avoid extreme temperature changes.
