While weed resistance management continues to be a hot topic in the area, professor Tristan Perez of the Queensland University of Technology spoke about how small robots could be enable a non-chemical method of weed management.

"With so many developments in research it is only a matter of time," he said.

He said that sensors could be used on the robots to collect information on how to better manage produce and crops.

Similarly, Brad Donald of B&W Rural in Moree said that images taken by drones could provide farmers with vital information on their crops by showing areas of low and high growth and allowing them to focus on resistive weeds, using different chemistry rather than spending $50 per hectare on the entire crop.

"At the moment we are still looking at how this technology can best be used," he said. "In 10 or 15 years, every farm might have one."

Organiser of the event John Cameron said the topics discussed were all chosen by farmers in the area.

In addition to information on management responses to increasing levels of herbicide resistance, there were also talks on sow timing and yield, the economics of good fallow weed management as well as grazing strategies and timing of stock removal from dual purpose cereals and oilseeds.

"It is high-tech now," Mr Cameron said.

"Growers tend to have a degree or higher education background in agriculture. They have got to be across computer software using a lot of high tech farming operations and a a lot of farmers out there could run multi-national corporations."

"Now we've got to be efficient with our commodity prices because to double the farming income you only need to increase by 15 per cent."
