Abstract
The characterization ad control of the black leaf spot disease infecting palasan (Calamus merrillii Becc.) plantation at Provident Tree Farm Inc. in Bo. Zillovia, Talacogon, Agusan del Sur was studied. Isolation of the microorganism in potato dextrose agar (PDA) medium under laboratory condition failed, an indication that the primary causal organism is an obligate parasite. However, the pathogenicity test using the leaf clip method showed similar signs and symptoms of infection as those observed in naturally infected leaves. The black leaf spot disease resembled the tar spot disease caused by Phyllachora sp. on other host species. The pattern of infection was hardly obsessed. Among Daconil, Benlate and Captan fungicides, Daconil appeared to be promising in controlling the disease.
