| Crops/Application timing |
| Barley
|
For optimum protection against fusarium head blight without compromising leaf disease control, apply as a preventative
spray when 70 to 100% of the barley main stem heads are fully emerged to three days after full head emergence.

| Wheat
|
For optimum protection against fusarium head blight without compromising leaf disease control, apply as a preventative
spray when at least 75% of the wheat heads on the main stem are fully emerged to when 50% of the heads on the main
stem are in flower.

Timing Guide
If planning on applying one fungicide application per year and flag leaf disease levels are low to moderate Bayer recommends waiting to apply a fungicide at head timing, protecting against various head diseases including FHB, leaf diseases and subsequently maximizing both quality and quantity of your yield.
Targeting the middle stage (shown below) will most often deliver the best results, but Bayer research has indicated that even if you apply slightly earlier or later, a positive ROI is still observed. Remember an application at head timing can supply both flag leaf protection and the added benefit of head protection throughout the grain fill period.
