| Uptake and Translocation |
Triclopyr is absorbed by both plant leaves and
roots. It is readily translocated through plants. It tends to
accumulate in meristematic tissues and is not readily metabolized
in susceptible plants. |
| Basis of Selectivity |
Tolerant species such as grasses rapidly metabolize
triclopyr. |
| Application Methods |
For deciduous and certain conifer species use as
a foliage spray when brush species are actively growing. Apply
either broadcast using a fixed nozzle (constant volume per ha)
or selectively using a spray gun (variable volume per ha). As
spray gun applications use a dilute spray mix, this type of application
must thoroughly wet the foliage, stem and root collar. Brush should
be treated after foliage is well developed and actively growing.
For conifer release in woodland sites, application should be made
in late summer after conifers have hardened off and deciduous
trees are in full leaf but prior to autumn coloration. Woody plants
may also be controlled by using basal bark, dormant stem and cut-surface
treatments. |
| Residual Activity |
Half-life in soil is approximately 30 days under
conditions that are favourable for microbial decomposition. |
| Unique Characteristics |
Apply only when there is little or no hazard from
spray drift. Small quantities of spray drift may injure susceptible
broadleaf plants. |
