Stop Sale for Turf Fungicides
June 10, 2015

On June 5th United Turf Alliance (UTA) voluntarily stopped sale of Armor Tech ALT 70TM fungicide due to reports of “compromised turf” on turfgrass in the Northeast. In addition, United Phosphorus Inc. (UPI) has also stopped sale of Viceroy 70DF TM (June 9th). Both products contain 70% aluminum tris (O-ethyl phosphonate) and are manufactured by Tersenderlo Kerley Inc. (TKI NovaSource). It is recommended at this time to avoid application of either product until further information is available. Currently, limited information exists and this is the safest course of action.

UTA is offering an opportunity to return Armor Tech ALT 70 TM for a full refund. More information can be found in the official stop sale release from UTA at UTA is currently conducting studies with multiple Universities in the New England region to determine the possible cause.
