Biological Information and Remarks
Foliage-applied selective herbicide that controls an-
nual and perennial grasses without injury to broad-
leaf plants. Use of a crop oil in spray increases its
effectiveness. Rainfall 4 to 5 hours after application
does not decrease grass control. It is absorbed by
foliage and translocated throughout the plant. Soil
persistence is short.
A soil-applied selective herbicide for control of some
annual grasses such as crabgrass, foxtail, and barn-
yardgrass in new seedings or established stands of
cool season turfgrasses. Should not be used in some
bentgrass strains or bermudagrass. Make treatments
just before germination of weeds to be controlled.
Readily absorbed by roots; less so by foliage. It
inhibits photosynthesis and root growth. It is de-
graded in soil microbially and does not persist for
more than one season.
A RESTRICTED HERBICIDE. A nonselective, soil-
applied herbicide which controls broadleaf weeds and
weedgrasses on noncropland. It is absorbed by roots,
and to some degree by foliage, and is translocated
upward. It is a photosynthetic inhibitor, but may
have additional effects. Prometon is more readily
adsorbed on muck and clay than on other soil
particles. It is broken down in soil microbially. It
persists in soil for more than one season.
