Application Information
How to Apply
:
Ground Application only. Do not apply by air.
Water Volume
: 22.5 - 45
L/acre.
Apply to weeds that are actively growing in the stages listed. Inferno Duo can be applied up to one week prior to
planting, or immediately after planting prior to crop emergence in spring wheat (excluding durum wheat). The
maximum rate of glyphosate applied when tank mixed with Inferno Duo is 182 g acid equivalent/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. Glyphosate is a non-selective, systemic herbicide that is absorbed through the foliage and
moves through the foliage and the roots, resulting in plant mortality.
Expected Results
Growth of susceptible weeds stops soon after application of Inferno Duo. Symptoms of Inferno Duo include
discolouration (yellowing, reddening, and purpling), with complete control taking up to 1-2 weeks. Annual weeds
susceptible to glyphosate 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
:
The following crops may be planted 11 months after an application of Inferno Duo.
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 an Inferno Duo application providing the following three
criteria are all met:
1.
Soil pH must be below 7.5.
2.
