EPA registers Curfew soil fumigant for turf use throughout Florida

The United States Environmental Protection Agency has granted a 24(c) label in Florida for Curfew soil fumigant, a product developed and manufactured by Dow AgroSciences LLC for control of parasitic nematodes (microscopic organisms that feed on and damage turfgrass roots).

“Nematodes inflict highly visible damage to turfgrass in sandy soil environments. They are a turfgrass manager’s nemesis,” says Dennis Lane, Dow AgroSciences product manager.

Curfew is applied with coulters and knife-shanks that open the turf before injecting the fumigant at least 5 inches below the soil surface through a delivery tube located behind the knife-shank. The cut turf seam is then closed and sealed by a press-wheel, or roller drum. Injection slits usually heal and disappear about 10 to 14 days after application. Turf fully recovers from treatment in 14 to 21 days.

Only certified applicators trained and approved by Dow AgroSciences who use the specialized equipment may apply Curfew soil fumigant. Currently, only two companies have been certified.

Additionally, research is underway to evaluate the use of Curfew to control mole crickets, grubs and other soil-borne pests.

*Curfew is not for sale or use in Dade County, Florida. Curfew is a Federally Restricted-Use Pesticide. Always read and follow label directions.
