Early trials with an innovative vineyard spraying system that uses sensors to accurately control spray rate and direction are showing encouraging results.
University of Queensland (UQ) researchers say their Pesticide Adjusted for the Canopy Environment (PACE) system has been able to reduce the amount of chemicals used by as much as 50 per cent, even at the full canopy stage.
‘You would get even greater savings early in the season and in winter it could be as much as 90 per cent’, said Senior Research Fellow Dr Andrew Hewitt. ‘As the crop grows you get less value from it, but even the minimum value is a 50 per cent per cent saving in chemicals for the same rate of coverage, and that is significant.’
