First report of laurel wilt disease caused by Raffaelea lauricola on sassafras in North Carolina
Plant Disease 103 (1), 155-155
Abstract: During 2018, dead sassafras trees were noticed in North Carolina, U.S.A. and examined. Bark was removed from four symptomatic sassafras trees, which exhibited black streaks of discoloration in the outer sapwood, evidence of small-diameter beetle holes (approximately 1 mm) near the base of the stem, and absence of flowers or expanding leaves. The fungus Raffaelea lauricola was isolated from the discolored sapwood of the dead trees. The identification was based on morphological characteristics and DNA sequence analysis.
