There are five core components of an effective Miravis^® Ace fungicide application strategy to protect wheat against Fusarium head blight.
​​​​​​​

1. Spray volume
   When applying Miravis^®  Ace, the recommended spray volume is 150 L/ha. The key is to use high enough water volume in order to produce an adequate number of droplets to get the job done and at a size that’s most effective.
   
   
2. Spray quality
   Coarse spray droplets are ideal for Miravis^® Ace applications. This allows for more spray days, better accounting for the variability in weather and needing to cover acres. Larger spray droplets can also maintain their trajectory a little longer so that when you use an angled nozzle to paint the front and the back of the head, you’re going to get better coverage. If you grow awned wheat varieties, data shows that coarser droplets have an increased ability to penetrate through the awn and down into the head because of their higher momentum.
   
   
3. Spray angle
   Using dual fans, twin fans or alternating fans is a good strategy for protection against Fusarium head blight. These nozzle configurations deliver multiple angles of attack onto your wheat stand. As the sprayer travels from left to right, the spray will paint the head once and then a second time. Coming in at those two angles is what gives you the coverage that will help preserve your grain quality.
   
   
4. Boom height
   With an angled spray, the spray only takes that angle for a relatively short distance – often around 30 to 35 cm from the nozzle. After that, the spray falls vertically under the force of gravity. In order to maintain the value of an angled spray, get the booms lower – closer to the target – so that the angle is still nice and strong getting to the heads.
   
   
5. Travel speed
   Travelling at 16 to 18 km/hour is an ideal speed. If you go much faster, you’ll get a spray shadow on the back side of the wheat and lose the benefit of twin angles of attack.
