Balsam Twig Aphid

Balsam Twig Aphid are very active and pesticide applications should begin on trees that will be going to market this year and next year. Remember to be out scouting for the hemlock rust mites and be ready to make a pesticide application if the economic threshold is reached.

Hemlock Rust Mites

Winters cold weather did not kill out the Hemlock Rust Mite. Rust mites are active and it would be good to be out scouting for rust mites during this beautiful weather. Even with temperatures supposed to cool down, the rust mites will remain active and possibly worsen. Go to the following website for more information on Hemlock Rust Mite and the thresholds to use in determining if you need to treat.
