Application Tips

  • Sphaerex should be applied preventively, prior to the onset of disease.
  • Avoid application when heavy rain is forecasted.
  • Apply when conditions are favourable for disease development.
  • Restricted Entry Interval (REI) is 24 hours for all crops and activities.
  • All crops can be grazed or fed to livestock 30 days after application.
  • Do not apply Sphaerex beyond the anthesis stage (>GS 69) when kernels begin milk development stage (GS 70).
  • Do not make more than one application of Sphaerex per year.
  • Rotational crops: A plant-back interval of 35 days is required for all crops not listed on the label.

 

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  Anthesis stage3
Wheat (durum, spring, winter) 75% head emergence to flowering4

 

1 For suppression of FHB, apply when 75-100% of the main stem barley spikes are emerged until 3 days later.

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 at early heading stage when anthers are yellow to white.

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.

5 Suppression at the 80 ac/case rate (0.53 L/ha).

6 For suppression of spot blotch only.

How Much to Apply

One case of Sphaerex treats 80 to 108 acres.

One drum treats 640 to 864 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

  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.
