Needle Blight

Garden Problems

Needle blight is a disease that usually affects pine trees, killing off the tip of the needles and branch tips.

Identify the problem
Needle blight is a disease that usually affects pine trees. Needle blight first appears as dark green, water-soaked spots on the needles. The spots become tan, yellow, or reddish-brown.
The tip of the needle beyond the band eventually dies leaving the base of the needle alive and green. Young trees are more likely to suffer damage than older trees.
How to solve the problem
- Spraying with Organic Super Sulphur will prevent new infections, but will not cure diseased needles.
- A spray of PLANThealth Spectrum or PLANThealth Rose Force in early June is sufficient to provide protection of new foliage. However, a second application three to four weeks later will provide more complete control.
Did you know?
- Needle blight is caused by the fungi Cyclaneusma minus and Dothistroma pini.
