Oak Wilt

The fungus is spread through root grafts between neighboring trees and by insects. Red Oaks are particularly susceptible to oak wilt. The infection causes leaf discoloration, defoliation and death in a very short period of time (from two months to one year).

Japanese Beetle

The Japanese beetle is native to Japan, but arrived in New Jersey before 1916. It’s suspected that the beetle larvae entered our country in a shipment of iris bulbs several years earlier, and before inspection of commodities began.

Japanese Beetle


This condition, if allowed to progress, will cause slow growth, leaf loss, and eventually tree death. Chlorosis is often caused by deficiencies of the micro-elements iron and manganese, and is particularly prevalent in oak.

Emerald Ash Borer

This metallic wood boring beetle was found in Detroit, Michigan and Ontario, Canada in 2002, and has continued to spread into neighboring states and eventually across the U.S. and Canada.
