Stagonospora Curtisii help

Hi Fred,

We've had bouts of Stagnospora off and on over the years. When it gets too
bad, a thick layer, I cut it out with a knife. I have on occasion
sterilized the infected spot with hydrogen peroxide, usually the drugstore
type, 3% H2O2, diluted 1 part to 3. The peroxide solution really doesn't
seem to hurt the plants.

Then treat it with fungicide. Benlate used to work fine for Stagnospora,
but that is long gone. Use systemics in any case.

Read up on fungicides sometime if the Stagnospora remains a problem. One
needs to use a systemic and a contact type, and switch between chemical
classes regularly, if re-applications are needed.
