Abstract

Metolachlor, oryzalin, and napropamide when chemigation-applied controlled large crabgrass more effectively than when spray applied in container-grown azalea, liriope, and Japanese holly. Oxadiazon and oxyfluorfen were equally effective as chemigation or spray applications. Azaleas were generally more susceptible to contact injury from sprays of oxadiazon and oxyfluorfen and large crabgrass interference than were holly and liriope.
