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).
Pre-harvest interval
30 days after application for barley, oats, rye, triticale and wheat.
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.
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.
