To meet the food requirement of the ever-growing popul
ation of the world the introduction of pesticides in
agriculture was a welcome move to control obnoxious weeds below the threshold limit and thereby
reduce the yield loss. But continuous use of synthe
tic herbicides in heavy doses creates environment
pollution and increases the number of herbicide resist
ant weeds. Hence, researches should be done to
find out some natural way for minimizing the dependency
on synthetic herbicides. The objective of this
article is to review the possibilities for using allelopat
hy to improve overall potentiality of weeds and crops
in natural weed management. Allelopathy is the favorable
or adverse effect of one plant on another due to
direct or indirect release of chemicals from liv
e or dead plants (including microorganisms). Although we
cannot discard use of synthetic herbicides complete
ly at the present situat
ion but their use can be
reduced up to a certain extent by utilizing allel
opathic potentiality as an alternative weed management
strategy for crop production as well as environmental benefits.
