The inhabitants of Nepal's hilly and Himalayan regions heavily depend on herbs and medicinal plants as a primary source of livelihood. In rural hilly and mountainous areas, the collection and trade of herbs remain the predominant source of income for a significant portion of the Nepalese population. Despite the economic importance of herb collection and trade, there has been limited systematic work on pest identification for exportable herbs in Nepal. This lack of study results in restricted options for effectively controlling diseases and insect pests affecting these herbs and their export. To address this gap, a comprehensive survey of major exportable herbs—Amla (Phyllanthus emblica), Pakhanved (Bergenia ciliata), and Nagbeli (Lycopodium clavatum)—was conducted from October 2021 to July 2022 in these herbs-producing major districts (Gorkha, Kaski, Dailekh, Salyan, Dhankuta, Dhading, Baglung, and Dolakha) in Nepal. The survey aimed to assess the distribution and occurrence of common diseases and pests in Nepal. The survey findings indicated that certain pathogens and pests were widespread, while others exhibited a more localized distribution. Specifically, the survey identified a total of 7 diseases, 8 insects, and 15 weeds affecting Amla, 4 diseases, 3 insects, and 3 weeds affecting Pakhanved, and 3 diseases, 5 insects, and 19 weeds affecting Nagbeli. These results offer valuable insights into the national status of pest issues related to exportable herbs in Nepal. These findings provide a localized perspective on the specific diseases and pests affecting the surveyed regions, offering valuable insights for targeted management and control strategies.
