The study describes that allelopathy increases the invasive potential of exotic plants which
would contribute a great deal of general models of invasive susceptibility in natural system
(13). Investigation of shifts in the tolerance f native species to the allelopathic effects of
invader may yield new insights into the mechanisms that drive the dramatic transformation of
the ecology of some species when they are introduced to new region of the globe [13].
Investigation is needed to isolate the individual chemical and to study their growth
inhibitory and enhancing effects. There is a need for the examination of the ecological role(s)
of the alleochemical in addition to its effect on plant growth. It is a must to design novel
techniques to quantify allelochemicals in soil environment. Future studies on the adsorption
and recovery of allelochemiclas from aqueous and soil solution might help to further
understand its role in the soil environment [31]. Field application and testing allelopathy
through improved methodology in the design is recommended. Other seeds and grass species
are suggested to be used for further alleloapthic investigation. Characterization, elucidation
