Abstract

Herbicide tests conducted over a period of 3 years indicated that 3-(3,4-dichlorophenyl)-l,l-dimethylurea (diuron) at 2.5 lb/A preemergence, or a,a,a-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) at 2.0 lb/A preemergence, incorporated, are safe and effective herbicides for weed control in gladiolus (Gladiolus grandiflorus). Applications of dimethylamine salt of 2,4-dichlorophenoxyacetic acid (2,4-D) applied as directed sprays at rates of 0.5 to 1.0 lb/A prior to spiking controlled late season weeds without apparent injury to the plants.
