Tree diseases, with oak wilt taking center stage, were the focus of the Tree Disease Identification and Management program held recently at the Urban Ecology Center at Phil Hardberger Park in San Antonio. Oak wilt is caused by a fungus and is spread by contaminated nitidulid beetles that bring it into fresh wounds on oak trees. Dr. David Appel, Texas A&M AgriLife Research plant pathologist in College Station and program’s key speaker stated that the fungus associated with oak wilt, ceratocystis fagacearum, will “always be a part of the Central Texas landscape,” it is heat sensitive and its spores are not airborne, so “several specific factors are needed for its transmission.”
Program presentations addressed the following:
- Identification and management of oak wilt and other common tree diseases
- City tree maintenance requirements
- Tips to minimize plant stress
- Proper pruning techniques
- Replanting techniques
- Managing tree insects.
