Common Oak Pests in Illinois Webinar

The summer series of University of Illinois Extension's Four Seasons Gardening program, which focuses on environmental stewardship and backyard food production, gets underway this month.

Quercus Quandaries: Common Oak pests in Illinois will be offered on Tuesday, July 26, at 1:30 p.m. Join Diane Plewa, Diagnostician at the University of Illinois Plant Clinic, as she discusses some of the most common problems seen on oaks across Illinois. Topics will include serious diseases such as oak wilt and bur oak blight, and less serious (but can look concerning) problems like tubakia leaf spot and galls. A few common insects that cause problems on oaks will also be discussed.

Program will be held at the U of I Extension Buildings , 700 S. Airport Drive, Springfield and 980 N Postville Drive, Lincoln. To reserve a packet of handouts at one of these locations, pre-register on-line at the Logan-Menard-Sangamon unit website at

Participants also have the option to listen to the webinar from home by registering at For participants who listen to the webinars from home, there is an additional program offered on Thursday evening at 6:30 pm during the same week as the Tuesday session.

The presentation will be via computer but will allow live discussion between the instructor and gardeners throughout Illinois.
