Abstract:  The toxic effect of dried berries powder of P. cubeba, dried fruit powder of P. longum and T. terrestris singly as well as in combination [binary(1:1) and tertiary (1:1:1)] were studied against snail I. exustus. Toxicity of these plant products were time and concentration dependent. Ethanol extracts of these plants were more effective than that of other organic solvents. 96 h LC50 value of column purified fraction of T. terrestris against I. exustus was 9.57 mg/l, where as 96 h LC50 values of column purified fractions of P. longum and P. cubeba were 11.57 mg/l and 10.93 mg/l, respectively. Binary (1:1) combination of P. cubeba (PC) + P. longum (PL) (41.78 mg/l) was more effective than P. cubeba (PC) + T. terrestris (TT) (42.17 mg/l) and P. longum (PL) + T. terrestris (TT) (55.84 mg/l) respectively; while tertiary (1:1:1) combinations of P. cubeba (PC) + T. terrestris (TT) + T. foenum-graecum (TF) (10.67 mg/l) was more effective than rest of the combinations. These plants can be used as potent source of molluscicides against the snail I. exustus.
