- Affected needles become lighter in color than normal or have an orange or brown tinge to them
- Needles may curl and become brittle
- Needle loss can occur singly or in clumps of multiple needles
Signs of Rhizosphaera Needle Cast Problems
The best way to identify a problem with Rhizosphaera needle cast is by looking at the needles on your tree. If you see yellowing of needles, or if they are falling from the tree, you may have a problem. Needles that turn blue in color could also mean that there’s an issue with the Rhizosphaera needle cast.
Treatment & Prevention of Rhizosphaera Needle Cast
For treatment and prevention of Rhizosphaera needle cast, spray fungicides on the infected needles, as well as on the ground around the tree. Spraying fungicides on the trunk, branches, and crown of your tree will help keep its foliage healthy and untainted by this fungus.
