Phytophthora help

[Dave.G.]

Does anyone know where I can find a list of susceptible species for Phytophthora ramorum? Spotted today a Sumach (Rhus typhina), with multiple bleeding lesions on the stem. Obviously no leaves to help identify the problem. Have a feeling I read somewhere that Rhus is highly susceptible?

The Forestry Commission website would be a good starting point...

 

Forestry Commission - Plant Health - Sudden oak death - phytophthora alert

There isnt a definitive list- they are constantly finding new species that are susceptible....

your best option is to contact the forestry commision and get them to have a look for you . yes it may seem a little ott but in view of how easily Phytophthora is spred i would not be inclined to leave it too long . hope this may be of some use to you , also on the FC website you can get info on disease controle areas near you , we have a few down here in cornwall and it can make doing tree work pretty difficult , however the fines for removing wood chip, timber ,brushwood form a Phytophthora site is pretty hefty .
