The active ingredient sodium chlorate is found in a variety of commercial herbicides. Sodium chlorate is not a restricted use pesticide. Check with specific state restrictions which may apply.
Sodium chlorate is a non-selective herbicide.
It is considered phytotoxic to all green plant parts. It can also kill through root absorption. The herbicide is mainly used on non-crop land for spot treatment and for total vegetation control on roadsides, fenceways, ditches, etc. If used in combination with atrazine, it increases the persistance of the effect. If used in combination with 2,4-D, it improves performance of the material.
