How it Works
Absorbed by foliage and roots. Disrupts plant metabolism causing growth to stop. Works best under good
growing conditions.
Expected Results
Grassy weeds will stop growing within 24 hours of application. After 7 - 10 days, symptoms start occurring. There
is a definite yellowing of the growing point; interveinal chlorosis and newest leaves are noticeably affected by
yellowing. Death occurs for grassy weeds in 14 - 21 days. Broadleaf weeds stop growing within 24 hours and weed
activity stops within 1 - 5 days. There will be a twisting of the growing point (result of the 2,4-D component) and
yellowing of the growing point (result of the imazamox).
Restrictions
Rainfall
:
Rainfall within 3 hours of application may reduce activity.
Grazing
:
Do not graze the treated crop within 14 days of application or cut for hay within 42 days of application.
Pre-harvest Interval
:
Wheat grain and straw can be harvested 79 days after treatment.
Restricted-entry interval
: 12
hours.
Re-cropping Restrictions
:
Spring wheat (including durum), spring barley, canaryseed, corn, chickpeas, field peas,
canola (all varieties), lentils, oats, flax and sunflower can be grown safely the year following an application. Mustard
(
condiment type only) may be grown safely the second season after application. Winter wheat can be grown safely
3
months after treatment. There are insufficient data for following with other crops. Conduct a field bioassay (a test
strip grown to maturity) the year before growing any crops other than those listed above.
Environmental Precautions
Toxic to small mammals, birds, aquatic organisms and non-target terrestrial plants. Avoid situations that may result
in drift. Leave 11 metres from the point of direct application and the closest downwind edge of sensitive terrestrial
habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, pastures, rangelands, and shrublands)
and sensitive aquatic habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams,
reservoirs, and wetlands). Do not spray exposed roots of trees and ornamentals.
Leaching
:
The use of Adrenalin SC may result in contamination of groundwater particularly in areas where soils
are permeable (e.g. sandy soil) and/or the depth to the water table is shallow.
Runoff
:
To reduce runoff from treated areas into aquatic habitats, avoid application to areas with moderate to steep
slope, compacted soil, or clay. Contamination of aquatic areas as a result of runoff may be reduced by including a
strip of untreated vegetation between the treated area and the edge of the water body.
Toxicity
Imazamox: Low acute mammalian toxicity. The LD
50
(
oral) for Adrenalin SC is >500 to <2,000 mg/kg.
Storage
Store above 5°C. Store in a cool, dry place away from children, animals, food, feed or fertilizers.
Keep from freezing.
