This "Virtual Renewal" will extend your Texas Oak Wilt Qualification for a period of three (3) years. To maintain your Texas Oak Wilt Qualification, you can either retake the two-day course and have a five (5) year extension or you can attend this course and extend for three (3) years. This three-hour workshop will discuss past oak wilt research and where current research is heading. It will cover the status of PCR for oak wilt diagnosis and the latest results of the "Micro/Macro" injection studies.

Each  participant that successfully completes the course  will maintain the status of Texas Oak Wilt Qualified. Your qualification will continue to be listed on the Texas Chapter website as well as on any handout and other materials referencing qualified individuals. While you will be listed on the website as Qualified, to be listed as an oak wilt vendor, you must have a TDA/Structural pesticide applicators license. (Required to sell any pesticide application.)
