Anti-mildew powder

I was given some anti-mildew powder by a friend in France (I don’t know the name of it but it’s pale yellow.) I want to use it on my Ajugas but I can’t get it to dissolve in water (to use in a spray bottle.) Any suggestions please?

    Could it be sulphur powder?  If so that comes in 2 types, one is wettable and can be used as you suggest, the other has to be 'puffed' onto the leaves, dry, like talcum powder.  Sounds like you have the latter.
    Read the 'How to use' section of this site:

    Thanks for that info - it makes sense as the powder is very fine. I will look for something to use as a ‘puffer.’ 🙂

    I agree with Bob.  Yes sulphur, usually matketed as.  Flowers of sulphur.  It is used in the storage of bulbs and tubers amongst many other applications.  Brushed onto cut surfaces of tubers etc, it forms basically an antiseptic barrier against infection.

    In the medical field, sulphur is used in many types of infections, bacterial and viral.  I would go as far to say.  Sulphur has no limited shelf life.  Discoveries have found that from the Biblical destruction of Sodom & Gamorrah,  the area is covered with deposits of brimstone, containing sulphur.  The sulphur still is flammable.

    Hello Lyn.  @Lyn Plant-Wells   I live in France and my father-in-law is a vigneron.  He gives me sulphur powder to "throw" onto my table grape vines.    Under "strict" orders to do it early morning before sunrise, no wind.   You can just take a small handful and throw it in a fan movement onto the leaves.  Lift leaves to get underneath.   Usually when the grapes are just starting to form and then another blast around May.  I put it on my roses and anything else susceptible to a bout of mildew.  I also use it on cuts and scratches as it is a great healer and dries out the cut and keeps it disinfected.   Good stuff to have around.
    A good hoeing is worth two waterings.

    Thanks tuikowhai34  I will give it a go. (Is the sulphur powder you use pale yellow?)  My Ajugas are affected - same last year.
