RNA interference in crop protection: opportunities and challenges during the transition to commercialization

Pest Management Science, Volume 82, Issue 7, Page 5971-5986, July 2026.
RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.
