compounds (chlorogenic, two ρ-coumaric derivatives, ellagic, hyperoside, rutin,
quercitrin, and kaempferol 3-O-glucoside) and other five low weight organic
acids [132]. Research study reported bioherbicidal potential of leaf extract of
Delonix regia on germination and seedling growth of field Convolvulus arvensis
and Triticum aestivum L. [133]. Result shows that lower aqueous concentration
(2.5% and 5%) and ethyl acetate (50, 500, 1000 ppm) of leaf extract of Delonix
regia inhibited germination, root length, shoot length, and seedling dry biomass of
Convolvulus arvensis.

Application of Allelopathy in the Agriculture Sectors
Agriculture practices are facing many challenges due to continuous use of
chemical in pesticides and insecticides. For sustainable agriculture practices,
scientists are exploring the use of natural resources for plant defense. To get
rid of environmental pollution caused by chemical pesticide, allelopathy research
becomes very important. Use of allelopathy provides a sustainable development
in the field of agriculture [134–137]. Utilization of allelopathy effect in agriculture is currently in use. For instance, to cover crop, in crop rotation,
intercropping or as green manure [91, 92, 138–148]. In the management of
nematode pest, IMP (integrated management practice) is the best method to
adopt, and this type of management is followed by Southwestern Nigeria.
Recently published research paper described the possible applications of plant
volatile organic compounds (VOCs) in agriculture [149] (Fig. 5). Volatile organic
compounds are released from leaves of all plants due to abiotic stress [150, 151]
or biotic stresses [152]. Isoprenoids are most of the volatile organic
compounds [153].

Effect of Allelopathy in Forestry Sectors
In the present time, management of forest using pesticides and herbicides is a
cause of concern. Synthetic herbicide has a toxic effect on wild varieties of
animals and plants [154]. Recent studies emphasize on the idea of managing the
forest using allelopathy [155, 156]. Allelopathy plays an important role in
the establishment of plant community and ecological succession by having an
impact on nutrient dynamics, competition between different species, and productivity of desired plant [157]. Research study reported that the rhizosphere
which contains signaling compound released by plants involving allelopathy is
of utmost use. This study concluded that for the purpose of weed management,
signaling compound can be a better option in the future. To study the signaling
property, there is a need of better understanding of molecular biology. Mechanism
of interaction between plant-plant and plant-pathogen is also directly linked to
forest management [158].
