The clinical picture of my cherry laurel hedge looked devastating. Everywhere curled and withered leaves. I suggest, the hedge drastically pruned and so advance eliminates many "pathogens". Caution: The infested shoots please not on the compost but disposed of separately!
Now I ordered Celaflor Pilzfrei Ectivo. A good price for the 250 ml bottle is between 12-13 euros. The delivery took place within one business day (Prime) as the product in Amazon stock is. I have attached the spray in a 3-liter spray bottle. The whole cherry laurel hedge on a dry day dripping wet wets well above. If possible, you should get as many as possible leaves. Each sheet transports the chemical into the plant, thereby increasing the effect. A good time for application is before or with the first bud. After 14 days, I have repeated the spraying and had the rest of the summer rest.
To prevent possible resistance or to enhance the effect, you can also inject alternating with other antifungal agents. Recommended also Compo 17785 Duaxo Universal is fungal free 150 ml.
All in all, an effective remedy for downy mildew on cherry laurel. But you should be aware that you can fight the fungus is very difficult to permanently. So he can witterungsbegünstigend resurface in the following year. Here retreatment is then advisable. Even a radical pruning of the infested shoots will not get you around. The agent "repaired" not affected leaves but makes the plant resistant to the disease.
Many luck and have fun in Euerem garden!
