where runoff water will drain across treated areas to
any body of water, agricultural lands, flower beds,
or where roots of shrubs and trees grow into
contaminated soil. Primary mechanism of action is
inhibition of cell division. Tolerant species metabo-
lize the compound to nonherbicidal metabolites.
Hydrolysis into nonherbicidal compounds is major
form of degradation, followed by normal soil, micro-
bial processes. Half-life in soil is 4 to 6 weeks. Rate
of degradation is increased by high soil temperature,
pH, oxygen level, and moisture.
