A common ArborCARE Plant Management (APM) recommendation is for three foliage spray and wash applications per year. Using an insecticidal soap product, this program assists in washing harmful dust and pollutants from your trees as well as controlling many damaging insects.
Spray applications are timed at 4 - 6 week intervals throughout the spring and summer months to match insect population pressures and coincide with occurrence.
Additional insect control measures, such as dormant oil, are recommended from time to time to target specific insect pests. Liquid soil drenching with the systemic insecticide Cygon is sometimes advisable for the control of Birch Leaf Miners.
ArborCARE’s licensed Plant Health Care Technicians have been trained in the safe use of environmentally friendly products. Chemical insecticides are implemented only when the situation warrants their use.
Winter protection for evergreens with an autumn application of an anti-desiccant is also available to protect tender plants from harsh Chinook winds.
