Elm Leaf Beetle

The Elm Leaf Beetle is a significant pest of Elm trees. The beetle and, in particular, its larvae can defoliate Elm trees rapidly during the summer months and reduce energy reserves for next year’s growth.

Repeated infestations and defoliation seriously weaken the tree and reduce the tree’s ability to collect and store Photosynthates.

Elm Leaf Beetle may never be eradicated but it can be managed. Eradication of Elm Leaf Beetle is extremely important for the long-term health of the tree.

Early prevention is necessary and there is only a small window of opportunity in August to October for effective treatment to target the Elm Leaf Beetle.
