I have a flat headed cedar borer killing off sections of my Emerald Green Arborvitae an wondering if your product will be effective in my situation?
Adonis 2F Insecticide/Termiticide is labeled for systemic applications of trees and shrubs for flat-headed borers. You will need to measure the tree at breast height all round for the circumference and divide that number by 3.14 (pi) and multiple by 0.1-0.2 fl oz. This will determine how much product will be needed for each tree or multiple 0.1-0.2 fl oz per height of any shrub. You will use a minimum of 10 gallons of water per 1,000 sq ft. We recommend that you contact a local arborist or Master Gardener at your local cooperative extension office to determine if the Emerald Green Arborvitae is not heavily already damaged prior to treating. Please let us know if you need anything else.
