Wj. Grichar, COMPARISON OF POSTEMERGENCE HERBICIDES FOR COMMON BERMUDAGRASS (CYNODON-DACTYLON) CONTROL IN PEANUT (ARACHIS-HYPOGAEA), Weed technology, 9(4), 1995, pp. 825-828
Field experiments conducted from 1990 through 1993 evaluated single an
d sequential applications of various postemergence graminicides for co
mmon bermudagrass control in peanut. UBI-1956 at 70 and 100 g/ha appli
ed early POST (EP) or sequentially, controlled common bermudagrass equ
ivalent to fluazifop-P applied EP or sequentially. Clethodim provided
variable common bermudagrass control. Clethodim applied EP provided be
tter control than sethoxydim while control from sequential clethodim a
pplications were equivalent to fluazifop-P. Fenoxaprop-ethyl alone fai
led to control common bermudagrass while the addition of fluazifop-P t
o fenoxaprop-ethyl improved control at least 22% in two of three years
. Quizalofop applied EP and fenoxaprop applied sequentially provided c
ommon bermudagrass control equivalent to fluazifop-P. Fenoxaprop-ethyl
or sethoxydim applied once or twice controlled common bermudagrass si
milarly. Peanut yield increases from common bermudagrass control were
erratic.
