Building on this, Davren has demonstrated the use of SAS as an effective insecticide against a range of insects which cause major economic loss in Agricultural commodities.


Davren has demonstrated that SAS treatment of major grains (i.e. wheat, barley, sorghum and rice) can fully control the 5 major pests which impact these key global commodities.

Davren has shown that for barley and sorghum the lead SAS treatments which fully control pests in these grains, also meet industry’s bulk density requirements. Further evaluation and optimisation of SAS products is underway to demonstrate the same for common Australian wheat classes.


Initial research on SAS was funded through the Plant Biosecurity CRC and intellectual property is owned by the Australian Plant Biosecurity Science Foundation Ltd and has been exclusively licensed to Davren Global Pty Ltd.

Davren continues to grow its know how in the characterization, handling and application of SAS as a alternative insecticide.


Images: Overlaid images from Scanning Electron Microscope and Energy-Dispersive X-ray Spectroscopy of four grain storage pests; lesser grain borer, rice weevil, red flour beetle and saw toothed grain beetle showing the successful transfer of synthetic amorphous silica from the grain commodity to the pests. The fluorescent colour indicates the presence of silica, rather than other elements or dust particles, at a coverage amount linked to mortality. Magnification x60.

A library comprising more than 2000 diagnostic images has been compiled and annotated using Scanning Electron Microscope (SEM) and matching Energy-Dispersive X-ray Spectroscopy (EDS). These confirm the presence of silica as SAS on target insect species after contact with SAS-treated grain.
