Crop pathogens, insect pests, and disease vectors are increasing at a faster rate due to climate change. It is spreading across geographical borders, thereby exposing the inefficiency of traditional chemical control measures. It is expanding throughout geographical boundaries, revealing the shortcomings of conventional chemical control strategies. The extreme environmental pressures have led to the evolution of climate-resilient Himalayan plant species, and these species, under-exploited as a source of bioactive compounds, hold potential in future bioactive research in sustainable agriculture and health studies on vectors.

As part of assessing the potential of two high-altitude medicinal plants, Saussurea simpsoniana and Hippophae rhamnoides (sea buckthorn), as natural biocontrol agents, this article under discussion focuses on their application as medicines in treating infections and inflammatory conditions. Available literature indicates that phenolic compounds, flavonoids, and terpenoids are some of the phytochemicals obtained from these species that have antimicrobial, antifungal, insecticidal, and repellent effects against a variety of plant pathogens and insect pests. These qualities enable them to be facilitated into environmentally friendly pest management programs and make them a candidate to be studied in regard to vectors.

In addition to bioefficacy, both species are experiencing escalating strain in ecology because of climate uncertainty, disturbance of habitats, and unsustainable harvesting and hunting methods, and conservation-compatible cultivation and utilization frameworks are necessary. The existing data on phytochemical profiles, intended organisms, biological processes, and suggested action mechanisms, along with research gaps that restrict translation progress. Overall, this paper indicates the prospect of climate-resilient Himalayan plants as multi-purpose biological platforms at the boundary of sustainable agriculture, vectors, and preventive biomedical applications.
