Researchers are using a combination of nanotechnology and algae fossils to develop a chemical-free way to protect stored grain from insects.
The non-toxic material, which uses the unique properties of single-cell algae, causes insects to dehydrate.
Insects can develop a resistance to currently used pesticides, which could threaten the 25 tonnes of grain Australia exports each year.
Due to the technology behind the solution, insects are unable to develop resistance to it and it has to be applied less frequently.
