Current strategies for crop pest control have limitations, with many pests developing resistance to traditional pesticides. dsRNA is emerging as a sustainable alternative for plant protection. However, the commercialization of dsRNA-based biocontrols requires large-scale production and effective delivery methods. Various production and delivery approaches are being explored, but challenges need to be addressed for widespread adoption of dsRNA biocontrols.
Current crop pest control strategies rely on insecticidal and fungicidal sprays, plant genetic resistance, transgenes and agricultural practices. However, many insects, plant viruses, and fungi have no current means of control or have developed resistance against traditional pesticides. dsRNA is emerging as a novel sustainable method of plant protection as an alternative to traditional chemical pesticides. The successful commercialisation of dsRNA based biocontrols for effective pest management strategies requires the economical production of large quantities of dsRNA combined with suitable delivery methods to ensure RNAi efficacy against the target pest. A number of methods exist for the production and delivery of dsRNA based biocontrols and here we review alternative methods currently employed and emerging new approaches for their production. Additionally, we highlight potential challenges that will need to be addressed prior to widespread adoption of dsRNA biocontrols as novel sustainable alternatives to traditional chemical pesticides.
