Abstract

HENSLEY, D.L. 1986. Fusilade 2000: toxicity test results. Am Nurseryman 163(10):67.

Selective postemergence herbicides have gained in popularity and use in nursery and landscape markets. One such herbicide, Fusilade (fluazifopbutyl), can be used to selectively remove annual and perennial grasses growing with a large number of landscape species. A new formulation, Fusilade 2000 (fluazifop-P-butyl) has been released. This material contains a greater proportion of the herbicidal isomer of the active ingredient and will replace the familiar 4E formulation. We applied Fusilade 2000 at a pressure of 30 pounds per square inch to 16 woody ornamentals. There was no evidence of foliar damage to any species caused by either solution of Fusilade 2000 two or four weeks after application. Fusilade 2000 appeared to be safe for use on all species studied at the rates tested.
