Abstract
A description is provided for Acidovorax anthurii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Anthurium andreanum, A. martinicense (Araceae;) by artificial inoculation: Dieffenbachia seguine (Araceae). DISEASE: Leaf spot of anthurium. Initially symptoms develop as necrotic lesions close to veins and leaf margins, which are frequently water-soaked and chlorotic. With age lesions blacken and turn grey. From the lesions, bacteria enter the leaf and spathe parenchyma and become systemic, resulting in tissue discoloration and ultimately death. Cover illustration shows symptoms on leaf. GEOGRAPHICAL DISTRIBUTION: CENTRAL AMERICA: Guadeloupe, Martinique, Trinidad & Tobago. TRANSMISSION: Unknown. Symptoms can develop by misting susceptible plants with bacterial suspensions or soil drenching (PRIOR & ROTT, 1989).
