See efficacy chart for target diseases. Use high rate for best results on powdery mildew. Efficacy significantly reduced if applied after stripe rust infection. To avoid unintended increase in vomitoxin when scab develops, do not apply after boot stage (Stage 10 on Feekes' or 45 on Zadoks' scale). For best yield response apply between flag leaf (Stage 8 on Feekes' scale or 37 on Zadoks' scale) and boot stages when target diseases threaten. Do not apply before jointing [stage 6 on Feekes' or 31 on Zadoks' scale (Fig. 1)]. Do not apply once flowering begins. Do not apply more than 0.77 quarts per acre per season. Do not harvest treated wheat for forage. Do not make more than 2 applications per season of this or other strobilurin (QoI) fungicide (pyraclostrobin or trifloxystrobin) to reduce development of resistance to this class of fungicides. |

See efficacy chart for target diseases. Efficacy significantly reduced if applied after stripe rust infection.

For best yield response apply between flag leaf (Stage 8 on Feekes' scale or 37 on Zadoks' scale) and boot stages when target diseases threaten. Do not apply once flowering begins for wheat and triticale. Do not apply after 50% heading for barley and rye. Do not apply more than 9 fl oz per application or 18 fl oz per season. To reduce development of resistance to this class of fungicides, do not make more than 2 applications per season of this or other strobilurin (QoI) fungicide (pyraclostrobin or trifloxystrobin). |
