Hosts: %1$s

· Gooseberry · Currant

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.

Trigger

The fungus spreads on the plant via its spores. In summer, infection rates increase.

Biological 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.

Preventive Measures

    Plant more resilient varieties in areas with high occurrence of Powdery MildewEnsure sufficient distance between the plants to allow for good ventilationGive sufficient light to plantsProvide a balanced nutrient supplyAvoid extreme temperature changes
