Emerald ash borer has caused a variety of problems all across North America.
Since its discovery, the insect has killed more than 50 million ash trees in more than 20 states and two Canadian provinces.
Denver and Fort Collins, Colorado-based has offered few tips on how to treat the pest.
Landscapers should determine if ash trees are present in a client’s yard. Ash trees have compound leaves with five to 11 leaflets, branches and buds that are in pairs directly across from one another, as well as have mature bark with diamond shape ridges.
When it comes to treating ash trees, there are several factors to keep in mind such as tree size, condition and proximity to the known affected area of the emerald ash borer.
Treatment options include either an injection in the soil or the trunk or a basal bark spray (spraying the trunk).
Ash trees have a better probability of surviving emerald ash borer if the tree has maintained a healthy status by being properly pruned, not infected by other pests and watered adequately.
