Beech Phytopthera

Caring Arborist · Dec 3, 2007

I would be interested in any information or sites dedicated to
control of Phytopthera in Beech. I started treating them in Newport RI
this year with Agri-Fos/Pentrabark. I also test and amend the soil naturally
with mostly Bio-Plex products. I have some info from Dr Hudler/Cornell, and met
with him in CT this year. I quote him in saying "if you're not treating beech trees for this you should be". Thank you!!

Are you talking about the kernoviae species? I didn't think it was here yet, or the ramorum?

Cut out the dead bark carefully, out to the dark line and without cutting into the wood. Scrape off all the dead stuff you can and then sanitize with the phosphite. Some will disinfect with 10% bleach (no splash) or hydrogen peroxide . A blowtorch can cauterize and leave the exposed wood smooth and hard. A blowtorch can also do collateral damage so like bleach it is seldom recommended, publicly.

Since Phytophthora (no "e") infects through the soil, inoculating with mycorrhizal and other beneficial organism may outcompete the pathogen. Organic Mulch is also essential for enzymatic and other bioactivity.

I also heard that "Subdue" works very well too..... (but that was a few years ago)
