natural compound requires less inspection for registration. So, cost of commercialization can be reduced [160].

Allelopathy and Genetic Manipulation
Allelopathic property can be transferred to different plants by biotechnology
or genetic engineering. In China, GM (genetically modified) rice with insect resistance property is at trial stage [161]. Golden rice 2 has been prepared by genetic
engineering. Certain enzymes which are obtained from maize are incorporated into
rice. This process leads to rise in concentration of beta-carotene (a precursor of
vitamin A). This variety of rice can be helpful in a deficiency disease of vitamin A
[162]. If a gene transfer for insect resistance is possible, then possibility of transfer
of allelopathic gene is also there. It is an area of research that can provide best option
for weed control in the future. There are many exciting opportunities in these
emerging fields [163].

Conclusion and Future Prospective
Allelopathy was considered as evil in previous times, but now it’s open for new path
for its numerous investigations and applications. There are numbers of phytochemical that are responsible for allelopathy of plant such as phenols, alkaloids, terpenoids, benzoxazinoids, and others. However, phenolic compounds are higher in
count responsible for their allelopathic potential. Weeds have become one of the
major causes for the losses in crop production, and allelopathy can play an important
role in weed management. Various methods such as mulching, intercropping, and
use of plant extract are used for weed control. Allelopathic properties have also been
used as bioherbicide and abiotic stress mitigation. Overall, in recent years, the
phenomenon of allelopathy has shown wider application and future prospective.
It will play a great role in a sustainable agriculture with a safe impact on the
environment. Allelopathy may facilitate to conserve the available resources and
can help to remove the problems raised by use of synthetic chemicals. It can be
also used to save the crop in economic and eco-friendly way.
