GENERAL INSTRUCTIONS
GROUP 4 FUNGICIDE

Fungicide Resistance Warning
RIDOMIL GOLD 25G is a member of the phenylamide group of fungicides. For fungicide resistance management RIDOMIL GOLD 25G is a Group 4 fungicide. Some naturally occurring individual fungi resistant to RIDOMIL GOLD 25G and other Group 4 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungi population if these fungicides are used repeatedly. These resistant fungi will not be controlled by RIDOMIL GOLD 25G and other Group 4 fungicides, thus resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use, Syngenta Australia Pty Ltd accepts no liability for any losses that may result from the failure of RIDOMIL GOLD 25G to control resistant fungi.
