As summer storms roll in across Australia's cropping areas so too does the risk of spray drift and multi-million-dollar damage bills, as growers work to reduce weeds on their farms.

Spray drift is when herbicides sprayed onto weeds carry onto other areas, doing damage to crops and pastures as well as polluting waterways.
