Each year I battle with a white fungi/mould on swan plants i am growing for next season, with a 30% loss. I spray anti fugal,and water them only in the mornings, but battle to keep them from being over come. They are in a sunny spot on racks facing North. What else can I do

Nothing. Powdery or downy mildew can be controlled, you can spray with copper every 2 weeks, and over winter too - the spores over winter in soil and bark.

Try mixing 2 tablespoons white vinegar with 2 litres water. spray that over - vinegar kills mould and prevents it recurring.

I will try that, and thank you . I have pulled all my remaining Toms out overcome with the same problem, but like your idea very much.

Just a thought, are you sure its a fungal disease? Mealy bug infestation has the appearance of white fungal infestation so spraying with fungal spray obviously won't have any affect (you already spray without result). Cheers!

It is a white fungus powder look on the leaves, and plants are now looking better after the last spray, although i will try the white vinegar in the future.
