Abstract
Experiments were conducted for 3 yr to evaluate the effects of the ethyl ester of fenoxaprop {(±)-2-[4-[(6-chloro-2-benzoxazolyl)oxy] phenoxy] propanoic acid} on rice (Oryza sativaL. 'Starbonnet′) applied at 112 and 168 g ai/ha or as two applications of 112 g ai/ha applied 10 to 14 days apart. Fenoxaprop did not adversely affect grain yield, panicle weight, seed weight, or seed germination when applied before the booting stage of both sprinkler-irrigated and flooded rice. Rice height was sometimes reduced by treatment at earlier growth stages, but yields were not affected. With the exception of applications at early jointing (internode elongation = 6 mm) in 1983, milling yield was not adversely affected by fenoxaprop applications made prior to booting of both sprinkler-irrigated and flood-culture rice. Applications during heading adversely affected most yield parameters.
