Fungicide Resistance Warning
ALTO 100 SL Fungicide is a member of the DMI group of fungicides. For fungicide resistance management the product is a Group 3 fungicide. Some naturally occurring individual fungi resistant to the product and other Group 3 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 this product or other Group 3 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 Crop Protection Pty Limited accepts no liability for any losses that may result from failure of this product to control resistant fungi.
Resistance Management
DO NOT apply more than 3 consecutive DMI sprays alone, before changing to a fungicide of a different activity group. Apply a maximum of 5 DMI sprays per season.
