Abstract

Several herbicides were evaluated for control of spring parsley [Cymopterus watsonii (Coult. & Rose) Jones]. The propylene glycol butyl ether esters and dimethylamine salt of (2,4-dichlorophenoxy)acetic acid (2,4-D) applied at 2 lb/A were 99% effective. Ninety-nine percent control was achieved also with 0.5 lb/A of 4-amino-3,5,6-trichloropicolinic acid (picloram) and 2,4-D amine + picloram at 0.4 + 0.1 lb/A, 2,4-D amine + picloram at 0.33 + 0.17 lb/A, and (2,4,5-trichlorophenoxy)acetic acid (2,4,5-T) + picloram at 0.25 + 0.25 lb/A.
