Effective RNAi-mediated control of the crop pest whitefly

Next-generation crop protection strategies must be clean and green as well as effective. Delivery of double-stranded RNA (dsRNA) as a BioClay spray to control the sap-sucking pest whitefly is one such strategy. This tool disrupts multiple whitefly life cycle stages in planta, with adjuvant-enhanced foliar uptake complementing the clay-mediated delivery of dsRNA.
