Diseases controlled
| Crop | Disease |
|---|---|
| Barley | Fusarium head blight (Fusarium graminearum)1 Leaf rust (Puccinia hordei) Net blotch (Pyrenophora teres) Powdery mildew (Erysiphe graminis) Scald (Rhynchosporium secalis) Spot blotch (Cochliobolus sativus)2 Stripe rust (Puccinia striiformis) |
| Oats | Crown rust (Puccinia coronata) Fusarium head blight (Fusarium graminearum)3 Stagonospora (Septoria) leaf blotch and black stem (Stagonospora avenae syn. Septoria avenae) |
| Rye and triticale | Fusarium head blight (Fusarium graminearum)4 Leaf rust (Puccinia recondita) Powdery mildew (Erysiphe graminis) Stripe rust (Puccinia striiformis) |
| Wheat (all types including durum wheat) | Fusarium head blight (Fusarium graminearum)5 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 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
- 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.
