Viruses are a major cause of plant disease with an estimated annual economic impact of over $30 billion. They account for nearly 50% of the pathogens responsible for emerging and re-emerging plant diseases worldwide. To confer resistance against these diseases RNA interference (RNAi) technology can be employed. Designing silencing molecules like dsRNA homologous to the viral genome has been the most common non-transgenic method to induce RNAi mediated resistance in plants. dsRNAs are carefully tailored and produced considering factors such as the type of virus, target genomic region, dsRNA size, and method of application to maximise their efficiency. With the advent of new technologies like nano-platforms, a sustainable carrier can be developed to deliver these molecules, enhancing their stability and its bioavailability. This innovative technology faces regulatory debates globally and lacks legislation for commercialisation. But this is an eco-friendly alternative to conventional pesticides that can revolutionize the future of plant viral disease management, providing a bio-safe and an evergreen solution.

Biosafety hazards can trigger a host immune response after infection, invasion, or contact with the host. Whether infection with a microorganism results in disease or biosafety concerns depends to a large extent on the immune status of the population. Therefore, it is essential to investigate the immunological characteristics of the host and the mechanisms of biological threats and agents to protect the host more effectively.

Cassava ( Crantz) plays a significant role in the livelihoods of people in Africa, particularly in Côte d'Ivoire. However, its production is threatened by begomoviruses which cause huge yield losses. Some weeds and food crops intercropped with cassava act as reservoirs, thereby facilitating the sustenance and propagation of Cassava mosaic begomoviruses (CMBs), along with other begomoviruses.

Natural products, especially specific metabolites found in many medicinal plants, exhibit extensive therapeutic potential due to their diverse biological characteristics. Among these compounds, diterpenes stand out for their active principles described in phytochemical studies. Diterpenes exhibit immunomodulatory effects by influencing the production of cytokines and other signaling molecules involved in the immune response.
