Stratego PRO – the evolution of the fungicide Stratego that you trust to give winter wheat a yield boost – can also help protect soybeans from diseases like white mould. The result is improved quality and yield for both your winter wheat and soybeans.

Stratego PRO offers:
improved yield versus competitors and Stratego fungicide and
white mould suppression with one pass

STRATEGO PRO Fungicide should be applied as a preventative disease control measure or at the very early stages of disease development. This could occur anytime during tillering or stem elongation. Typically, one application from the tillering up to flag leaf emergence is required. A second application may be made if needed. DO NOT apply within 14 days of the first treatment. DO NOT apply STRATEGO PRO Fungicide after early heading (the head is half emerged).

Disease: Septoria leaf blotch (Septoria tritici), Powdery mildew (Erysiphe graminis)
Rate: 440 mL/ha
Timing: Single application: 4-leaf stage up to early heading (GS 14-55). Two applications: First application: 4-leaf stage to flag leaf stage. Second application: before early heading (GS 14- 55), but not within 14 days of the first application. Continue application as needed on a minimum 7 day interval.

TANK MIXTURES WITH HERBICIDES IN WINTER WHEAT: STRATEGO PRO Fungicide may be tankmixed with Buctril M or Infinity herbicides only during the 2 to 4-leaf stage in the fall or from the time growth commences to the early flag leaf stage in the spring. Follow staging restrictions on the Buctril M or Infinity herbicide labels.
