Potential of pesticidal plants in harnessing ecosystem services and crop production
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 11, Issue 5
Abstract
In crop production the external inputs such as artificial fertilizers and synthetic pesticides are taken by the majority as the immediate solution. This product-driven approach overlooks the side effects like contaminated food products, the death of non-target organisms, health hazards to animals and human beings, water and soil pollution to mention but a few. This review intends to solve the challenge through crop production using locally available resources which are friendly to the environment, human health and the entire ecosystem. One way to achieve this could be by harnessing the ecosystem services provided by pesticidal plants which are valued for their medicinal, deterrents, or repellents qualities in control crop pests in field or store. They also provide nectar, forage, and habitats for beneficial insects; add organic matter to the soil, creation of micro-climate, control of soil erosion, regulation of water quantity and quality, windbreak, and nutrient cycling. However, there is a limited knowledge on how best to manage the field crop with pesticidal plants so as to accrue the mentioned services. This review intends to uncover different techniques which can be employed in field crop with pesticidal plants in a way that will lead to maximizing crop yield with the possible minimum inputs.
