Biological Information and Remarks
A soil-applied herbicide used as a soil sterilant in
noncrop situations. It is a strong oxidant. When in
contact with combustible materials, it may cause fire.
Clothing and vegetation contamination with chlorate
or its solutions are DANGEROUSLY FLAMMA-
BLE. Follow instructions on the label completely.
Often mixed with fire suppressant such as borate. It
persists in soil for more than a year.
A soil- or foliage-applied herbicide for noncropland
control of herbaceous broadleaf weeds and some
methyl 2-[[[[(4,6-di =
grasses. At moderate rates in the South, it can
control broadleaf weeds selectively in established
bermudagrass. It is not very toxic to the root system
of most trees and many woody shrubs, and may be
useful as directed spray at low rates for control of
vegetation under trees. It is absorbed by roots and
foliage of weeds, and translocates throughout the
plant. It arrests cell division in the growing tips of
roots and tops, and gradually the plant is killed. The
lower the soil pH, the higher the organic matter, the
greater the adsorption on soil. Chemical hydrolysis
and microbial activity decompose sulfometuron in
soil. The half-life during summer is about 4 weeks.
Little decomposition occurs in frozen soil.
