[NAFEX] gummosis question

Captafol is no longer legal to sell in the U.S.  It's registration was voluntarily withdrawn in 1999, so I doubt you could find any, even if you wanted to.  It seems it was a pretty bad carcinogen.  It was a fungicide, so I doubt it would do much for your gummosis, which is generally caused by bacteria.  I suppose you've checked for borers?  Dormant copper sprays are about the only option available for bacterial gummosis.

  Subject: [NAFEX] gummosis question

  I have half a dozen four year old Red Haven peaches in my orchard. Couple years ago I accidently damaged the base of one trunk with my mower. Soon thereafter found the tell tale brown syrup oozing out. Thought it might be sap at first but it's definitely gummosis. I want to treat it this year coming. Anyone have experience with eliminating. I've read about Captafol but haven't found enough info. Hate to lose the whole tree but I'll take it out if it's a real threat to my other peaches.
  Thanks in advance
