Description
Macroptilium atropurpureum (D.C.) Urb. is a viny tropical legume, native to central America and tropical South America (Tothill 1966), with potential for pasture use in south Florida and other parts of the tropics and subtropics (Kretschmer, 1972). Isariopsis griseola Sacc. causes leaf spotting and defoliation of M. atropurpureum cultivar 'Siratro' in Florida (Lenne and Sonoda, 1985), in early spring and late fall, when forage availability is minimal. The disease is also present in native populations of M. atropurpureum in South and Central America (Lenne and Sonoda, 1985). I. griseola is generally considered to cause only minor damage (Lenne and Sonoda, 1985), however, in the fall of 1986 it caused heavy defoliation on some accessions in a planting of 174 M. atropurpureum accessions being screened for forage characteristics at the University of Florida, IFAS, AREC, Ft. Pierce. The following is a report of the reaction of various accessions of M. atropurpureum to I. griseola.
