Kabatina blight is not clearly understood, and fungicide timing has not been effective in disease control. It is important to remove and destroy infected twigs in dry weather.
Infection is thought to occur through wounds the previous season.
Reports indicate that disease-resistant varieties are in development, so ask for these at your nursery. Some information about Kabatina blight can be found in Sinclair, Lyon, and Johnson s book, Diseases of Trees and Shrubs. Both of these juniper blights are discussed and pictures provided.
