How do I rid of needle cast on spruce trees?


Docket DF Fungicide is a very good product for needle cast. It is labeled to be used on spruce trees. It is NOT labeled for blue spurce trees. You will make the first application in the spring when the new growth is 1/2 to 2 inches in length. You will make additional applications 3-4 weeks intervals until conditions improve. You will use 2.5 to 5.0 lbs per 100 gallons of water.
