Dry conditions continue to put stress on Nebraska trees, especially in the western Panhandle, where exceptional drought persists. Prolonged drought can increase trees’ vulnerability to borers, bark beetles and diseases.
The latest Forest Health Report also highlights Emerald Ash Borer, which has now been detected in 20 Nebraska counties, along with several pests and diseases to watch for this summer, including Thyronectria canker, mimosa webworm, honeylocust spider mites, pine bark adelgid, woolly apple aphid and magnolia scale.
During dry periods, deep watering can help trees withstand stress and reduce their vulnerability to pests and disease.
