Phytotoxicity trials on bedding plants, Los Angeles County, Calif., evaluated the effects of 1X, 2X, and 4X rates of Evisect 50SP, Dimilin 25WP, Zolone 3E, Broot 50WP (1X = 0.5 lb (AI)/100 gal) and Avid 0.15E (1X = 0.001 lb (AI)/100 gal). Two flats, each containing 9 pony paks of 6 plants, were evaluated per treatment for each species. The materials were applied to runoff with a 2.5 gpm piston pump portable sprayer with a hand wand outfitted with a 5003 Spraying Systems nozzle @ 150 psi on 20 Mar and 10 Apr 20-21°C and 25-27°C, respectively. Weekly phytotoxicity readings were compared to a water check for 2 wk after each application
