| Crop and/or Non-Crop
Registrations |
Field corn, spring and winter wheat, spring barley,
spring rye, oats, summer fallow and stubble, pastures, red fescue,
lowbush blueberries and turf; non-crop areas such as roadsides,
utility rights-of-way and railways. |
| Sensitive Weeds |
Annual, perennial and biennial broadleaf weeds
and numerous brush species including conifers. Particularly effective
against velvetleaf,
Canada
thistle, field
bindweed and various triazine-resistant broadleaf weeds. Control
is best when weeds are small and actively growing. |
| Uptake and Translocation |
Readily absorbed by roots, stems or leaves and
then translocated to other plant parts. |
| Basis of Selectivity |
Metabolism by tolerant species. |
| Application Methods |
Preemergence or postemergence in field corn. For
all other crops and non-crop uses, postemergence applications
are recommended. |
| Residual Activity |
Half-life in soil is approximately 30 days. Residue
carryover into the next season is not a problem when applied at
rates recommended for crop situations. |
| Unique Characteristics |
Dicamba is often mixed with grass herbicides or with phenoxy
herbicides to provide a broader spectrum of weed control. Spray
drift is toxic to sensitive plants in the same manner as 2,4-D,
thus similar precautions should be followed. Cold weather conditions
and/or subsequent high rainfall after dicamba application may
lead to temporary corn injury particularly on early-season hybrids
in Eastern Ontario. There is also a possibility of dicamba vapour
drift from treated plant foliage during high temperatures (in
excess of 25°C). At higher rates, dicamba can be toxic to
trees and shrubs having roots under the treated areas. See sections
on Herbicide
Drift and Reduction of Herbicide Drift.
