Australian farmers spend over $800 million per annum on herbicides. The proposed technology can reduce herbicide usage by 80 per cent (i.e. over $640 million per annum saving) and improve crop yields by 30 per cent. Precision application of herbicides, fertilisers and nutrients to weeds and crops has both economic and environmental benefits which will increase farm profits and boost Australia's export sales. Reduced chemical loads on ecosystems will benefit the environment and reduced chemicals in the food chain will benefit the health of Australians. This development will put Australia at the cutting edge of precision spray technology and has numerous spin-off applications in many sectors.
