I just ordered Agrimycin 100 (500ml)in liguid form to mitigate bacterial leaf disease that seems to have taken up in my roof garden. I would appreciate anybody with experience using it to advise me
the solution to use and the method to apply it. I've read that
it's a good idea to spray early as a preventative...which I will do next year...but would it still be helpful to spray the tress that are just developing it now. A few recently
got infected during a rainy spell. The main two that were causing it (they had it when I bought them) are already out of the garden...but I have a couple that show signs of it.
One quite extensively - a Purple Leaf Sand cherry that I've had for over 20 years. Any advice would be appreciated. thanks
