Technological Advantage

The biopesticide formulation is conventionally applied to the crop, while the encapsulating agent prevents the RNA molecules from environmental degradation, ensuring it remains available on the plant surface for uptake by feeding insects.
As the CSFB emerges and feeds on the treated crop, they simultaneously ingest lethal doses of our RNA-based biopesticide, capable of withstanding the harsh gut environment within the insect.


Once ingested and taken up into the insects’ cells, the RNA targets a specific gene essential for survival.
With the targeted protein no longer being produced, the beetle’s ability to thrive is impaired, therefore leading to decreased feeding and ultimately mortality, thereby reducing crop damage and improving yield.


How RNAi works
RNA AgriBio Ltd is developing a new generation of crop protection based on a naturally occurring biological process called RNA interference (RNAi). Our technology uses Spray Induced Gene Silencing (SIGS), where a biodegradable RNA spray is applied to crops to specifically target harmful insect pests such as the Cabbage Stem Flea Beetle (CSFB) Psylliodes chrysocephela, one of the greatest threats to UK oilseed rape production.
