| comparative pathogenicity, biocontrol efficacy, and multilocus sequence typing of verticillium nonalfalfae from the invasive ailanthus altissima and other hosts. | verticillium wilt, caused by verticillium nonalfalfae, is currently killing tens of thousands of highly invasive ailanthus altissima trees within the forests in pennsylvania, ohio, and virginia and is being considered as a biological control agent of ailanthus. however, little is known about the pathogenicity and virulence of v. nonalfalfae isolates from other hosts on ailanthus, or the genetic diversity among v. nonalfalfae from confirmed ailanthus wilt epicenters and from locations and hosts n ... | 2014 | 24134719 |
