This is this time of the year again, when powdery mildew appears on my pepper starts… 20% milk solution works as preventive, but boy, what a smell it creates overtime. I am trying Actinovate this year and can’t find any information if and for how long I can keep prepared solution. I made 500ml, using 1/2g of powder and used only 250 ml. Can I keep the rest till next application? Making less than 500 ml is problematic, I am not sure if I can trust my scales with measuring quarter of a gram. Anybody had any experience or have some information on storage?
