Application Information
How to Apply
:
Ground applications only.
Do not apply by air.
Water Volume
: 20 - 40
L/acre.
Application Tips
Initial crop injury may be observed after application but this is outgrown and should not affect yield. Severe crop
injury will occur as a result of spray overlap. Avoid sprayer overlap.
Do not spray Altitude FX if temperatures of +5ºC or lower are forecasted within 3 days of application. Temperatures
near freezing (below 5ºC) will prevent optimum herbicide performance, as weeds are not actively growing. Do not
apply more than once per year. For best results, treat CLEARFIELD wheat during warm weather when weeds are
actively growing and soil moisture is adequate for rapid growth.
How it Works
Absorbed through the foliage and roots. Disrupts plant metabolism causing growth to stop within 24 hours. Visible
symptoms appear within 7 - 10 days and, depending on environmental conditions, weed death occurs within
14 - 21
days after application.
Restrictions
Rainfall
:
Rainfall within 3 hours of application may reduce activity.
Grazing
:
Do not graze or silage the treated crop within 14 days of application or cut for hay within 42 days
of application.
