The ATGA MRLs mobile application (App) provides withholding period (WHP) recommendations for the fungicides and insecticides registered for use in table grape production. The WHP recommendations are determined by the export market maximum residue limit (MRL) and are based on the residue results of trials conducted in Australia and overseas. As these results may not reflect the residue levels in all growing conditions and grape varieties, it is advised that grape growers test their produce for agrochemical residues to confirm that export market MRLs are being met.
