promoter of Arabidopsis thaliana. The plant-incorporated protectants (PIPs) can also
be used for developing bioherbicides, but there were no successful examples of
bioherbicide PIPs, which should be improved by transgenic research. The PIPs will
be a promising biotechnology strategy, so further study is needed to identify their
mechanism of action (Duke 2003; Bertin et al. 2008). All conferred techniques offer
a strong knowledge of allelopathy. Nonetheless, a thorough understanding of such
complex communications among this phenomenon leads us one step forward for the
progression of novel strategies for finding innovative bioherbicide for a sustainable
and cleaner environment.
5 Conclusion
The exploitation of allelopathic weed control through rotational crops, intercrops,
cover crops, mulches, crop residues, and allelochemical water extracts will offer
sustainable agriculture and a cleaner environment and, moreover, viable weed
control because of the useful impacts of these techniques on soil fertility status,
organic matter, and ecosystem biodiversity. Furthermore, endeavors to create
responsiveness to industries for formulating allelochemical-based natural herbicides,
researching the allelopathy of unexplored fields, applying the hormesis knowledge
for dose-response for allelopathic interactions among species, and conception of the
allelochemical mechanism of action and their fate in different environment and
ecosystem will advance the competence of allelopathic weed control. Scanty understanding of the transportation and biological degradation of allelochemicals in soil or
the population genetics of allelopathic plant species, elucidating signal transduction
pathways related to allelochemical synthesis and mode of action makes the allelopathic technique as complex for imeediate practical utility. There is an adequate
scope to research donor and recipient plants. Various scientific research fields, such
as molecular breeding, transgenic technology, plant tissue culture, stress physiology,
plant source-sink relationship, allelopathy hormesis, ecobiology, and identifying
novel allelochemicals to be intergrated for exploring the potential of allelopathy
for cleaner environment. High-throughput analytical techniques in allelopathy studies could be utilized for investigating and describing distinctive agrochemicals that
are derived from characteristic natural sources. Allelopathy grasps out promise for
improvements in crop production through discovering novel eco-friendly
bioherbicides with new modes of action, beneficial to crops but noxious to weeds,
and without the formation of dangerous residues, less pollution, and restricted land
degradation that leads toward the cleaner environment and green cover. Finally, the
genetic manipulation of crops through various biotechnological strategies to evolve
crops that carry genes and traits for the desirable attributes of a successful and strong
competitor to their weeds. Allopathic research for a sustainable cleaner, pollutionfree environment would be a strong motivating scientific target that is currently
being pursued.
