Summary

Needle cast or needle blight diseases are common problems of pines (Pinus spp.) in nurseries, Christmas tree plantings, and landscapes. Dothistroma needle cast and Lophodermium needle cast are the two most common fungal diseases that primarily infect pine trees. These diseases are often confused because their symptoms look similar. Accurate identification is important since management timing differs between them.
