Etiology, Epidemiology, and Management of Hyphoderma Gummosis

Hyphoderma gummosis, a disease causing wood decay, serious dieback, tree decline, and eventual death of citrus trees was first observed in 2000 in several orchards in Tulare, Ventura, San Luis Obispo, and Riverside Co. causing serious losses to some lemon growers (Marais et al., 2001a,b). Mainly older lemon orchards (between 35 and 50 years old) are affected.
