ABSTRACT
Roccella montagnei Bl. emend. Awas. were assayed against polyphagous insect, Helicoverpa armigera (Hbner). Among the different crude extracts tested, the pupation was nil in methanol (1%) and hexane extract (5%), which was on par with aqueous extract (5%). The formulation of water extract of R. montagnei is better compared to other solvent extracts, as potential antipest agent against H. armigera.]]>
