Diseases controlled
| Crop | Disease |
|---|---|
| Barley | Ergot (Claviceps purpurea)1 Fusarium head blight (Fusarium graminearum)2 Leaf rust (Puccinia hordei) Net blotch (Pyrenophora teres) Powdery mildew (Erysiphe graminis) Scald (Rhynchosporium secalis) Spot blotch (Cochliobolus sativus)3 Stripe rust (Puccinia striiformis) |
| Oats | Crown rust (Puccinia coronata) Ergot (Claviceps purpurea)1 Fusarium head blight (Fusarium graminearum)4 Stagonospora (Septoria) leaf blotch and black stem (Stagonospora avenae syn. Septoria avenae) |
| Rye and triticale |
Ergot (Claviceps purpurea)1 Fusarium head blight (Fusarium graminearum)5 Leaf rust (Puccinia recondita) Powdery mildew (Erysiphe graminis) Stripe rust (Puccinia striiformis) |
| Wheat (all types including durum wheat) | Ergot (Claviceps purpurea)1 Fusarium head blight (Fusarium graminearum)6 Leaf rust (Puccinia recondita) Powdery mildew (Erysiphe graminis f. sp. tritici) Septoria/Stagonospora leaf blotch (Septoria tritici or Stagonospora nodorum) Spot blotch (Cochliobolus sativus)2 Stem rust (Puccinia graminis) Stripe rust (Puccinia striiformis) Tan spot (Pyrenophora tritici-repentis) |
1 For suppression of Ergot only at the 80 acre/case (0.53 L/ha) rate.
2 For suppression of FHB, apply when 75 – 100% of main stem barley spikes are emerged until 3 days after.
3 For suppression of spot blotch only.
4 For suppression of FHB, apply at anthesis stage or early panicle stage when anthers are yellow to white.
5 For suppression of FHB, apply when at least 75% of mainstem cereal heads are fully emerged until the end of anthesis.
6 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
- Ensure the spray tank is clean before use.
- Fill the spray tank 1/2 full of water and start agitation.
- Add the required amount of Sphaerex to the tank.
- Continue agitation while filling the remainder of the spray tank.
- After use, clean the spray tank according to the label precautions.
