Herbicides Available for Treating Soil for Vegetation Control
This volume contains an approach to control vegetation in Reclamation switchyards,
substations, and maintenance areas.
substations, and maintenance areas.
The Department of the Interior and the Bureau of Reclamation are recommending an
integrated pest management approach to all vegetation control procedures. Although
the herbicides listed may be a solution for controlling vegetation in Reclamation
switchyards substations, and maintenance areas, it is recommended that more
environmentally compatible measures be taken whenever and wherever possible.
A least toxic approach should be considered when selecting a vegetation control method.
This means selecting a biological control method over a mechanical or chemical control
method if similar results can be obtained.

This means selecting a biological control method over a mechanical or chemical control

Some alternative vegetation control methods to be considered around maintained
facilities include grazing (of open areas), planting of low growing grass varieties,
moving, cultivation, and the use of vegetation inhibiting materials such as geotextiles,
gravel (road mix/road base - this mixture of gravel and fines does a better job of
holding herbicides than uniform sized gravel), riprap, asphalt, and concrete. In the
event that a herbicide is needed, an integrated approach should be considered,
combining one or more of the above recommendations with a herbicide. Herbicide
selection should follow the least toxic approach, i.e. selective, nonselective,
nonselective persistent.

Some herbicides have been omitted from the listing because they are considered to be
problem herbicides, i.e. ground water contaminants, toxic to wildlife, etc. Conversely
some herbicides which are not considered to be true soil applied herbicides have been
omitted, but may provide very good vegetation control and at the same time be less
toxic than the herbicides listed. The sample trade names listed are not necessarily the
only manufacturer of the listed chemical and any listing of the trade name does not
constitute any endorsement of that product. It is recommended, that if a herbicide is
selected over other means of vegetative control, the selected herbicide be verified
appropriate for the intended use and/or area by local county agricultural agents,
herbicide manufacturers, herbicide labeling information, or similar authority.

NOTE: Some lateral movement of the herbicides listed may be experienced, and
precaution should be taken to prevent erosion of treated soil. Strict adherence to
application procedures and material safety obtained from the product label should be
maintained.
