Choose a versatile, effective weed control solution for warm-season grasses
By Lane Tredway, Ph.D., technical services manager, Syngenta
During June and July, summer annual and perennial weeds grow larger and more objectionable, often requiring post-emergent herbicide applications during this time. Manuscript® and Monument® 75WG herbicides are powerful options for lawn care operators managing bermudagrass and zoysiagrass landscapes.
Manuscript controls tropical signalgrass, crabgrasses, dallisgrass and other labeled weeds in bermudagrass and zoysiagrass. It has a unique turf safety profile and control spectrum thanks to its phenylpyrazolin chemistry, and it includes a safener, cloquintocet-mexyl, to further enhance turf safety. Manuscript is packaged with Adigor™ surfactant, which was specifically designed to maximize Manuscript absorption and translocation in target weeds.
For best results, Manuscript should be applied:
- With two spot treatment applications (9.6 fl. oz./10,000 ft.2) on a 14- to 21-day interval
- In 40 to 80 gallons water per acre with 0.5% v/v of Adigor or an MSO surfactant
Target weeds should be actively growing, and not under stress from drought or other factors, to maximize absorption and translocation of the active ingredient.
Monument 75WG is the standard for post-emergent control of major sedge species, including purple nutsedge, yellow nutsedge and green kyllinga. It also controls more than 30 grass and broadleaf weeds including clovers, spurges, Virginia buttonweed and most cool-season grasses.
As an SU herbicide, Monument 75WG inhibits new root and shoot growth in sensitive weeds, resulting in plant death after 14-21 days. The active ingredient is effectively translocated to the growing point and other below-ground structures to provide more effective control of tough perennial weeds compared to other SU herbicides.
With excellent turf safety to bermudagrass and zoysiagrass turf, Monument 75WG:
A program approach to weed control
- Can be applied as a broadcast or spot treatment at rates of 0.35 to 0.53 oz./A
- Can be tank mixed with dicamba, fluroxypyr or other broadleaf weed herbicides to broaden weed control spectrum without reducing weed control
After controlling grassy weeds with a product like Manuscript, broadleaf weeds and sedges often proliferate. For a broader spectrum of weed control, Manuscript can be tank-mixed with Monument or dicamba herbicides. Do not mix Manuscript with products containing 2,4-D as they are likely to reduce control of target grasses.Manuscript causes little-to-no injury or growth regulation to bermudagrass or zoysiagrass when applied at broadcast or spot treatment rates.
