Tips for Identifying Honeysuckle Leaf Blight (HLB)
HLB disease symptoms first develop in mid to late spring and continue throughout the summer, peaking in prevalence and destruction in June and July. Here are some characteristic HLB symptoms to look for:
Early symptoms appear as yellow areas on young leaves that grow into tan/brown dead patches as the
disease progresses.- Symptoms are often present on the edges of leaves, giving a scorched appearance.
- Infected leaves become distorted or curled.
- Sometimes a speckled pattern may emerge due to scattered plant cell death.
- Severe disease may result in totally dry, dark brown, twisted leaves that fall off the plant prematurely.
A sign of the fungus may be seen on the underside of infected leaves (under humid conditions), which
appears as a thin, silvery-white layer of fungal spores.
