Monument herbicide now registered for use in California

Monument herbicide from Syngenta Professional Products is now registered for post-emergence weed control use in commercial turf markets in California, including golf courses, sod farms and commercial property management. The active ingredient in Monument, trifloxy-sulfuron sodium, provides excellent control of sedges and green kyllinga in certain warm-season turfgrass species, including Bermudagrass and Zoysiagrass.

“With the addition of Monument to the Syngenta Professional Products line-up, turfgrass managers in California and other states now have a solution for excellent sedge control and overseeding management in the transition zone,” said Dean Mosdell, technical field manager, Syngenta Professional Products.

A sulfonylurea herbicide, Monument demonstrates control of key weeds including purple and yellow nutsedge, annual sedges, oxalis, green kyllinga and various other weeds in warm season turfgrasses. With low use rates, a repeat application in four to six weeks may be necessary for control of certain weeds.

In overseeded Bermudagrass, Monument can be used to remove Poa trivialis and/or perennial ryegrass for enhanced spring transition. Cool-season turfgrasses are very sensitive to Monument, therefore lower use rates will promote a more gradual removal of the over-seeded turf species.

Monument is available in a 75WG formulation. Members of GreenPartners, the flexible loyalty program that rewards customers for their Syngenta turf and ornamental product purchases, will receive points for Monument purchases.
