How it Works
Broadband herbicide is absorbed by the leaves and is rapidly translocated to the growing points of leaves and stems
of target weeds. It must be applied early post emergence to the main flush of actively growing annual broadleaf and
grass weeds. Thorough coverage of the plants is essential for consistent control.
Expected Results
Broadband is a systemic, post-emergence herbicide. Broadband herbicide stops growth of susceptible weeds rapidly.
Actively growing, susceptible grass and broadleaf weeds stop growing within 48 hours of treatment; however,
typical symptoms (discolouration) of dying broadleaf weeds may not be noticeable for 1 to 2 weeks after application.
Depending on species, growing conditions and crop competition, leaves and growing points of annual grass weeds
turn yellow within one to three weeks after application. Further colour changes and loss of vigour will be observed,
followed by a browning and control 3 to 5 weeks after application.
Restrictions
Rainfall
:
Broadband alone can be used one hour before rainfall.
Grazing:
Wait a minimum of 7 days before grazing livestock on treated crops.
Pre-harvest Intervals:
Observe minimum interval to harvest of 60 days after treatment for grain and straw and of 30
days after treatment for hay.
Re-cropping
:
On fields sprayed with Broadband, no crop may be seeded until the following year. There are no crop
rotation limitations the year following application of Broadband.
Environmental Precautions
The active ingredient, pinoxaden, is non-toxic to birds and insects (bees) and slightly toxic to aquatic organisms. The
active ingredient, florasulam, is practically non-toxic to insects (bees), aquatic invertebrates (water flea), fish, and is
non-toxic to slightly toxic to birds. Avoid contamination of water supplies or aquatic habitats. Observe buffer zones
specified on the label.
Toxicity
Acute oral toxicity: LD
50
(
