Abstract: Host range study revealed that BLB can produce visible symptoms on Cyperus rotundas, Cynodon dactylon, Paspalum scrobiculatum, Leersia oryzoides and Oryza sativa and symptoms were not appeared on Zea mays, Sesamum indicum, Vigna radiate, Vigna mungo and Glycin max. However, five out of ten hosts plant take 48-58 hours to symptoms expression.
