Beech Leaf Disease
_____________________________________________________________________________________________________________________
Beech Leaf Disease affects beech tree species (particularly American beech) and has been spreading rapidly in New Jersey & other states.

BLD is caused by an invasive nematode. A nematode is a microscopic round-worm that cannot be seen with the naked eye. Wind, rain, and wild life carry the nematodes from tree to tree. Birds have the potential to carry the nematodes long distances.
BLD causes rapid decline and mortality that can occur between 2 to 10 years depending on tree size.
RUTGERS extension service
recommends the use of Polyphosphite 30. Polyphosphite materials are thought to work by stimulating the natural defense response in treated trees.
Homeowners or their landscapers can apply Doggett DOG-PHITE 0-0-29 to trunk and roots. This can be done with a watering can.
