hardened off by cold weather or drought stress may show delayed symptoms and result in reduced levels of weed
control. Effectiveness may be reduced if spray mixture remains in the tank for more than 24 hours.
How it Works
FirstStep/Spike are absorbed by foliage and roots, inhibits cell elongation. StartUp/Spike-Up are non selective
systemic herbicides that move through the foliage into the roots, resulting in plant mortality.
Expected Results
FirstStep/Spike rapidly stop growth of susceptible weeds; however, typical symptoms (discolouration) of dying
weeds may not be noticeable for 1 to 3 weeks after application, depending on growing conditions and weed
susceptibility. Annual weeds susceptible to StartUp/Spike-Up will wilt and yellow with 2-4 days. Perennial weeds
will wilt and yellow with 7-10 days.
Rainfall
:
If rain occurs within 4 - 6 hour after application , control may be reduced.
Movement in Soil
:
FirstStep/Spike move little in the soil. StartUp/Credit have negligible leaching in the soil.
Restrictions
Re-cropping
:
FirstStep Complete/Spike-Up have a minimum re-cropping interval of 2 months between application
and seeding of canola, flax, lentils and alfalfa.
Grazing
:
Do not graze treated areas within 7 days of application.
Toxicity
FirstStep/Spike and StartUp/Credit have a very low acute mammalian toxicity. FirstStep/Spike have an acute oral
LD
50
(
rats) = >5,000 mg/kg. StartUp/Credit have an acute oral LD
50
(
rats) = 4,320 mg/kg. Non-toxic to bees, birds
and fish.
