Application Tips
Higher spray volumes needed with a dense crop canopy and/or large weeds. Weeds should be less than 10 cm tall
or across at application. Triton C left in the tank for more than 24 hours might have reduced effectiveness. When
crop is under stress, application may result in crop injury such as temporary crop colour lightening or a slight height
reduction. Clean sprayer immediately after application and use ammonia to deactivate Triton C.
How it Works
Absorbed through foliage. Inhibits cell elongation. Causes stem elongation, leaf cupping or curling.
Expected Results
Growth stops immediately. Discolouration of dying weeds may not be noticeable for 1 - 3 weeks after application,
depending on growing conditions and weed species. Poor results may be expected if there is improper mixing,
timing, coverage or when weeds are under drought stress.
Restrictions
Rainfall
:
Rainfall within 6 hours of application may reduce weed control.
Grazing
:
May not be grazed of fed to livestock within 77 days of application on wheat, 80 days on barley.
Pre-harvest Intervals
:
Allow 77 days between application and harvest on wheat, 80 days on barley.
Re-cropping
:
Wheat (spring and durum) and barley have no re-cropping interval. Canola, flax, field pea, lentil and
sunflower can be seeded 10 months after application. Oats can be seeded 12 months after application. Under dry
conditions and light soils, the re-cropping interval for flax and lentil should be 12 months. Triton C should not be
used on land where potatoes or vegetables are part of the rotation.
Environmental Precautions
Triton C is toxic to aquatic organisms and non-target terrestrial plants. Leave a 1 metre buffer around water bodies
and 15 meters between applied area and sensitive terrestrial habitats. Do not use soils that have large coarse textured
areas, eroded knolls, or calcium deposits.
Runoff
:
Avoid runoff by using recommended buffer zones.
Toxicity
Triton C is a combination package of 2 products: Refine SG and quinclorac: Refine SG: Low oral toxicity. Oral LD
50
(
rats) = > 5,000 mg/kg. Quinclorac: Moderate oral toxicity. Acute oral LD
50
(
rats) = > 2,200 mg/kg.
Storage
Store in a cool, dry place.
