Research to improve summer spray knowledge

New research in Western Australia’s eastern grainbelt is expected to help growers make better informed decisions on spraying early germinating summer grass weeds.

The Grains Research and Development Corporation (GRDC), through its Regional Cropping Solutions Networks (RCSN) initiative, is funding the research in the eastern part of the Kwinana Port Zone.

GRDC western grower services manager Darren Hughes said growers understood the importance of spraying summer weeds to conserve as much moisture as they could for their cropping operations, particularly if they were farming in a lower rainfall zone.

“But the big question that many are asking is: ‘If we get rain early in the summer season and are still harvesting grain crops, what will be the impact if we don’t spray summer weeds early?’,” Dr Hughes said.

“It is hoped the trial, supervised by grower group Southern Dirt, can provide local farmers with more detailed information about the influence of summer weeds on nutrition, disease and soil moisture.”
