I am treating several groupings of Parsoni Juniper which are exhibiting Juniper Tip Blight (phomopsis or kabatina fungus). I believe that multiple treatments will be required and I am wondering what a good rotation treatment (alternative to Clearys 3336F fungicide) would be.
To treat for Tip Blight with Clearys 3336 you can use Propiconazole and Chlorothalonil in a rotation, doing two applications in a row before rotating. The infected twigs and branches should be pruned off about two inches back into live wood, and then prunings should be destroyed. Prune only when plants are dry, and sterilize tools between each cut by swabbing them with a solution containing 1 part rubbing alcohol and 3 parts water or use a solution of 1 part household bleach to 9 parts water.
