For suppression of FHB, apply when 75 – 100% of main stem barley spikes are emerged until 3 days after.

2 For suppression of spot blotch only. 

3 For suppression of FHB, apply at anthesis stage or early panicle stage when anthers are yellow to white. 

4 For suppression of FHB, apply when at least 75% of mainstem cereal heads are fully emerged until the end of anthesis. 

5 For suppression of FHB, apply Sphaerex as a preventative application, beginning when at least 75% of mainstem wheat heads are fully emerged until anthesis stage (Growth Stage (GS) 61 – 69), early heading stage when anthers are yellow to white. Optimal timing is at anthesis, or until 50% flower. 

Application Tips

  • Sphaerex should be applied preventatively, prior to the onset of disease.
  • Avoid application when heavy rain is forecast.
  • Apply when conditions are favourable for disease development.

 

Pre-harvest interval

30 days after application for barley, oats, rye, triticale and wheat. 

When to Apply

Crop            Staging   
Barley 75% spike emergence to 3 days after full emergence1
Oats Early panicle to flowering2
Rye and triticale  75% head emergence to early panicle3
Wheat (durum, spring, winter) 75% head emergence to end of flowering4

 

1 For suppression of FHB, apply when 75 – 100% of main stem barley spikes are emerged until 3 days after. 

2 For suppression of FHB, apply at anthesis stage or at early panicle stage when anthers are yellow to white.

3 For suppression of FHB, apply when at least 75% of mainstem cereal heads are fully emerged until the end of anthesis.

4 For suppression of FHB, apply Sphaerex as a preventative application, beginning when at least 75% of mainstem wheat heads are fully emerged until anthesis stage (Growth Stage (GS) 61 – 69), early heading stage when anthers are yellow to white. Optimal timing is at anthesis, or until 50% flower.

How Much to Apply

One case of Sphaerex fungicide will treat 80 to 108 acres.

Barley, oats, rye, triticale, wheat (all types) 160 to 216 ml/ac (0.4 to 0.53 L/ha)

 


BASF recommends the use of the higher rate to guarantee maximum protection against leaf diseases and FHB.

 

Water volume

Ground Application 40 L/ac (10 gal/ac)
Aerial application 20 L/ac (5 gal/ac)

 

Mixing order

  1. Ensure the spray tank is clean before use.
  2. Fill the spray tank 1/2 full of water and start agitation.
  3. Add the required amount of Sphaerex to the tank.
  4. Continue agitation while filling the remainder of the spray tank.
  5. After use, clean the spray tank according to the label precautions.
