Hi all,

I'm growing some "Parade" roses down in TAS and noticed, just as a large
number of buds are developing, some white powdery spots developing on many
of the leaves. I'm guessing it's a fungal problem and seem to remember
reading somewhere that spraying a 1/8 (ratio?) solution of milk and water
might help.

Is this correct? If not, can anyone suggest another way of treating this?

TIA
