Resistance Management Strategy for:

Group 2                    Dicarboxamides;
Group 3                    Demethylation inhibitors (DMI);
Group 4                    Phenylamides (PA);

Group 7 + 11           SDHI + Quinone outside inhibitors (QoI);
Group 11                  QoI;
Group 11 + 2           QoI + dicarboxamides;
Group 11 + 3           QoI + DMI;
Group 12                 Phenylpyrroles (PP);
Group 14                 Aromatic hydrocarbons (chlorophenyls and nitroanilines);
Group 21                 Quinone inside inhibitors (QiI);
Group 28                 Carbamates; and
Group 33                 Phosphonates.

1. Fungicide groups that are classified as medium to high risk for fungicide resistance development; Groups 1, 2, 4, 7 (N3), 11 and 21 should be rotated as a key feature to reduce the development of resistance.
2. Do not apply consecutive sprays of fungicides from the same activity group, unless mixed with a registered fungicide from a different mode of action group with no known resistance. 
3. Group N3 nematicides are also classified as Group 7 fungicides and consecutive application should be avoided, even if targeting different pests/pathogens.
4. If consecutive sprays are applied of fungicides from a high risk fungicide group (i.e. Groups 1, 2, 4, 7, 11 or 21) they must be followed by at least the same number of applications of fungicide(s) from a different group(s) before the same high risk fungicide is used again.
