1 Suppression only.
2 Apply when 75-100% of main stem barley spikes are emerged until 3 days after.
3 Apply at anthesis stage or at early panicle stage when anthers are yellow to white.
4 Apply when at least 75% of mainstem cereal heads are fully emerged until the end of anthesis.
5 Apply preventively, 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.
Pre-harvest interval
30 days after application for barley, oats, rye, triticale and wheat.
Crop | Staging |
---|---|
Barley | 75% spike emergence to 3 days after full emergence |
Oats | Early panicle to end of flowering |
Rye, triticale |
Early heading to end of flowering |
Wheat (all types) | 75% head emergence to end of flowering |
One case of Sphaerex treats 80 acres and one shuttle treats 640 acres for fusarium head blight.
For fusarium head blight | 216 ml/ac (530 ml/ha) |
BASF recommends the use of the higher rate to guarantee maximum protection against leaf diseases and FHB.
