Syngenta launches new turf herbicide in Florida to safely control mature weeds in summer

  • Manuscript® herbicide has been granted a Special Local Needs label in Florida 
  • Contains new active ingredient for golf courses and sod farms in Florida to control tropical signalgrass and bull/thin leaf paspalum 
  • Ideal in summer heat, when desirable turfgrass can quickly regrow

GREENSBORO, N.C., USA, June 28, 2018 – To help golf course superintendents and sod growers in Florida manage mature weeds in the heat of summer, Manuscript® herbicide from Syngenta has been granted a FIFRA Section 24(c) Special Local Needs label in Florida. This new, highly active herbicide has been specially designed to provide post-emergence control of tropical signalgrass and bull/thin leaf paspalum in certain warm-season turf species on golf course fairways, tees, roughs and on sod farms.

​​​​​​​“Syngenta is excited to bring new technology to superintendents and sod growers in Florida for managing tough-to-control tropical signalgrass,” said Stephanie Schwenke, turf market manager for Syngenta. “Not only will Manuscript help with these long-standing weed challenges, but in doing so its effectiveness can also help reduce labor for hand-weeding and allow the desirable turf to quickly recover during the summer.” 

Manuscript is powered by pinoxaden, a new active ingredient for the turf industry, which has an advanced form of ACCase mode of action. It helps control tropical signalgrass and bull/thin leaf paspalum in bermudagrass, zoysiagrass and St. Augustinegrass (sod only). This herbicide can also be used in the heat of summer, when desired turfgrass is actively growing and will fill in rapidly.

Manuscript also features a built-in safener that speeds the metabolism of pinoxaden in desirable turf to help improve turf safety without sacrificing control of mature, difficult-to-control weeds. This allows for effective spot treatments, further improving selectivity against tough weeds. Its turf safety profile also enables applications near non-target species like ornamental beds and shrubs to help increase confidence during application.

“Manuscript was specially designed for turf safety and potent activity on certain weeds,” said Lane Tredway, Ph.D., technical services manager for Syngenta. “This unique combination provides a tool for controlling tropical signalgrass and other weeds, while increasing populations of desired turf species. Manuscript will help improve the uniformity, playability and aesthetic quality of treated turf.” 

Manuscript is packaged with Adigor surfactant from Syngenta, which is custom-built for use with Manuscript for improved rainfastness and faster weed control. Using Adigor with Manuscript maximizes the quantity and rate of absorption of pinoxaden, as well as the degree of translocation once pinoxaden is in the plant.

The federal label from the Environmental Protection Agency for Manuscript is anticipated to be available later this year. For more information about Manuscript in Florida, visit
