I have a peach tree contained by the back patio. It is about A little below six feet. The top subdivision had died bad and what used to be considered 'suckeres' Became the plants branches. Recently something that looks like white fungus started growing on some stems, leaves and at the exposed roots. I dont want to cover the roots until I know if the fungus is not contagious.I want to really get hold of rid of it.. I also Know that it is not powdery Mildew. I also want to know if its just a run of the mill symptom or if its helping the plant strive in Florida. Also Tips on diligence would be nice.
Answers:    yep its a fungus-- type of mold like moss growing on a tree within the swamp -- caused by drizzly and damp weather i get the same piece on mine-- fixing to git me some spray at ace rugged ware and see if i can git rid of it--i dont think it will impair the tree--or is it contagious to people--other trees maybe-- also it could be poision to any pets that might sample it--i m contained by mississippi--close to jackson
. It could be several diseases, like FUSICOCCUM or LEUCOSTOMA CANKER , or VERTICILLIUM WILT.
Your largest tree nursery should know how to fix the problem. You might enjoy to remove the tree.
