Abstract

Indigenous Exserohilum monoceras isolate 1125 was evaluated for its efficacy on different Echinochloa species. Exserohilum monoceras spores, prepared at 103, 104, 105, 106 and 107 spores/ml concentrations and sprayed onto E. crus-galli, showed increased infectivity with increasing spore concentration. Disease progress of E. crus-galli at various leaf development stages revealed the highest area under the disease progress curve (AUDPC) was at the 4-leaf stage (535.69 unit2), followed by the 3-leaf (446.75 unit2), 2-leaf (377.22 unit2) and 6-leaf stage (263.72 unit2). The fungus was also tested on 4 species of Echinochloa. The results showed that the AUDPC was highest for E. crus- galli var formosensis (693.33 unit2), followed by E. crus-galli var crus-galli (638.33 unit2), E. oryzicola (470 unit2) and E. colona (447 unit2). The study illustrated that E. monoceras is a potential fungus for biological control that can be further developed into bioherbicide.
