Bedding Plant Phytotoxicity Evaluations, Summer, California, 1985

Abstract

Phytotoxicity trials on bedding plants, Los Angeles, Co., CA, evaluated the effects of 1X, 2X and 4X rates of Avid 0.15E (0.01 lb (AI)/acre), Broot 50W, Dimilin 25W, Zolone 3E, and Evisect 50SP (1X = 0.5 lb (AI)/100 gal). One flat, containing 9 pony paks with 6 plants, was evaluated per treatment rate for each species. The materials were applied to runoff with a 2.5 gpm piston pump hand sprayer at 180 psi on 15 Jul (temp = 25-28°C). Phytotoxicity readings were compared to a water check 22 and 29 Jul.
