treatment for gloomy scale on red maples
Looking for either systemic insecticide (such as Safari) or horticultural oil to treat gloomy scale on red maples.
Red Maples are very sensitive to oils, soaps and other insecticides and for this reason we do not make product recommendations for this ty pe of tree. You should contact a local arborist in your area for product recommendations. Please go to this link to contact your local extension office http://www.csrees.usda.gov/Extension/index.html
