Restrictions
Rainfall
:
Do not apply if rain is expected in 1 hour.
Grazing
:
Do not feed or graze treated fields. Wheat grain or straw from treated fields may be fed to livestock.
Pre-harvest Interval
:
Observe minimum interval to harvest of 80 days after treatment.
Re-cropping restrictions
:
The following crops may be planted 11 months after application.
Black soil zone
:
Barley, canola (all varieties), durum wheat, field bean, field pea*, flax, spring wheat.
Brown soil zone
:
Spring wheat.
Dark Brown soil zone
:
Barley, canola (all varieties), durum wheat, field bean, field pea*, flax, spring wheat.
Gray-Wooded soil zone
:
Barley, canola (all varieties), field pea*, spring wheat.
*
Field peas can be successfully grown the year following an Everest application providing the following three
criteria are all met:
1.
Soil pH must be below 7.5
2.
Organic Matter content must be above 4%.
3.
Precipitation must be equal to or above the 10 year average (minimum 100mm within 60 days of application
in year of application). Rotational crops can be adversely affected if rainfall is below normal (10 year average)
during the year of application.
Everest applications to eroded knolls in the Dark Brown and Black soil zones with low organic matter (less than
2%)
and high pH (greater than 7.5) or to Gray Wooded soils with highly variable soil texture and organic matter may
result in delayed development or reduced yield of rotational crop.
Environmental Precautions
Do not allow this chemical to drift on to other crops, especially canola, tame oats, or other non target crops.
