Herbicides
Water Volume
: 22.5 - 45
L/acre
Apply to actively growing weeds. Pre-Pare Complete/Pace herbicides can be applied up to one week prior to
planting, prior to post-planting and prior to crop emergence in spring wheat (excluding durum wheat). The maximum
rate of glyphosate applied when tank mixed with Pre-Pare 70 WDG is 182 g active ingredient/acre.
How it Works
Flucarbazone sodium is a systemic herbicide that is absorbed by both leaves and roots and moves rapidly to the
growing point of the plant. StartUp/Traxion are non selective systemic herbicides that move through the foliage into
the roots, resulting in plant mortality.
Expected Results
Growth of susceptible weeds stops soon after application of Pre-Pare. Symptoms of Pre-Pare include discolouration
(
yellowing, reddening, and purpling), with complete control taking up to 1-2 weeks. Annual weeds susceptible to
StartUp/Traxion will wilt and yellow with 2-4 days. Perennial weeds will wilt and yellow within 7-10 days.
Restrictions
Rainfall
:
Do not apply if rainfall is expected within 1 hour of application.
Grazing
:
Do not graze treated fields or use green crop for feed.
Pre-harvest Interval
: 80
days.
Re-cropping Restrictions
:
The following crops may be planted 11 months after an application of Pre-Pare.
Black Soil Zone
:
Barley, canola (all varieties), durum wheat, field beans, field peas*, flax, spring wheat
Brown Soil Zone
:
Spring wheat
Dark Brown Soil Zone
:
Barley, canola (all varieties), durum wheat, field peas*, flax, spring wheat
Gray Wooded Soil Zone
:
Barley, canola (all varieties), field peas*, spring wheat
*
Field peas can be successfully grown the year following a Pre-Pare 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 100 mm 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. Use certified seed and good agronomic practices to reduce the effect on rotational crops.
Pre-Pare/Pace applications to eroded knolls in the Dark Brown and Black Soil zones with low OM (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.
Toxicity
Pre-Pare and StartUp have a very low acute mammalian toxicity. Pre-Pare has an acute oral LD
50
(
rats) =
>5,000mg/kg. StartUp has an acute oral LD
50
(
rats) = 4,320 mg/kg. Traxion has an acute oral LD
50
(
rats)
>5,000 mg/kg. It is non-toxic to bees, birds and fish.
Storage
Does not require heated storage. Store in cool, dry place.
