Monument 75WG is a selective post-emergence herbicide for the control of certain weeds in commercial warm season turf markets, including golf courses, sod farms and commericial property management. A sulfonylurea herbicide, Monument 75WG provides excellent control of a broad range of weeds including all major categories of sedge species, green kyllinga , oxalis and various other grass and broadleaf species in Bermudagrass and Zoysiagrass.
Growth of susceptible weeds is inhibited soon after application of Monument 75WG. The leaves of susceptible plants normally turn yellow, red or purple after several days, followed by necrosis and death of the growing point. Complete plant death occurs 1-3 weeks after application, depending upon weed species, growing conditions, etc.
Monument 75WG controls weeds by inhibiting a biochemical process that produces certain essential amino acids necessary for plant growth. The inhibited enzyme system is acetolactate synthase (ALS).
Apply Monument 75WG in 1 to 2 gallons water per 1000 sq. ft.
If pH of water carrier is less than 5.5, use a buffer solution to
raise pH to near 7.0. Do not mix with acid forming compound
in the spray tank. Control of susceptible weeds may not occur
for up to 4 weeks after treatment.

The lowest rate allows for a more gradual transition,
however the turf may be temporarily discolored. If
applied to dormant bermudagrass, some delay in green-up
may be observed. A good bermudagrass base should be
present before using this product to remove overseeded
