Abstract

Abstract Phytotoxicity of Mavrik 2F was evaluated on 15 woody ornamentals typically produced in south Alabama. Plants were grown in an amended pine bark-peat moss medium. Rhododendron X ‘Glacier’ and ‘Coral Bells’ were grown under 47% shade; other species in full sun. Overhead impulse sprinklers provided irrigation. Treatments were applied to all leaf surfaces to runoff 18 Apr., 2 May, and 16 May with hand-pumped, compressed air sprayers. Six single-plant replicates per species were arranged in a completely randomized design. Phytotoxicity evaluations were made 1 week after each application and 4 weeks after the last application.
