2 For suppression of ergot only at the 80 acre/case (0.53 L/ha) rate.

3 Suppression only. Apply when 75-100% of main stem barley spikes are emerged until 3 days after.

4 Suppression only. Apply at anthesis stage or at early panicle stage when anthers are yellow to white until the end of anthesis.

5 Suppression only. Apply when at least 75% of mainstem cereal heads are fully emerged until the end of anthesis. 

6 Suppression only. Apply Sphaerex as a preventative application, beginning when at least 75% of mainstem wheat heads are fully emerged until the end of anthesis (Growth Stage (GS) 61-69).

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            Staging1   
Barley 75% spike emergence to 3 days after full emergence
Oats early panicle to end of flowering
Rye and triticale  early heading to end of flowering
Wheat (durum, spring, winter) 75% head emergence to end of flowering

 

1 Optimum staging for fusarium head blight and ergot management. Sphaerex can be applied earlier for leaf disease management. Performance is best when applications occur prior to foliar disease development or at the onset of disease symptoms.

How Much to Apply

One case of Sphaerex fungicide will treat 80 to 108 acres.7

Barley, oats, rye, triticale, wheat (all types) 160-216 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 10 gal/ac (100 L/ha)
Aerial application 5 gal/ac (50 L/ha)

 

7 For optimal results on fusarium head blight and flag-leaf disease management, BASF recommends using Sphaerex at the 80 acre/case rate. For suppression of ergot, the 80 acre/case rate is required.

 

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 with water.
  5. After use, clean the spray tank according to the label precautions.
