Abstract

In field trials conducted in 1989 and 1990, fifteen postemergence herbicides were tested for phytotoxicity to kenaf. Clethodim (110 g ai ha–1), fluazifop (220 g ai ha–1), quizalofop (70 g ai ha–1), and sethoxydim (210 g ai ha–1) were not phytotoxic to kenaf in the cotyledonary stage. MSMA (2.2 kg ha–1) was not phytotoxic to kenaf at the cotyledonary or 35-cm stage. All other herbicides applied postemergence to kenaf caused significant injury.
