Wk. Vencill et al., EFFICACY AND ECONOMY OF WEED MANAGEMENT-SYSTEMS FOR SICKLEPOD (SENNA-OBTUSIFOLIA) AND MORNINGGLORY (IPOMOEA SPP) CONTROL IN SOYBEAN (GLYCINE-MAX), Weed technology, 9(3), 1995, pp. 456-461
Field experiments were conducted in Tifton, Midville, and Athens, GA t
o determine economic net returns from PRE-broadcast, PRE-banded, POST,
and POST-directed herbicide treatments and inter-row cultivation in c
onventional-tillage soybean. Metribuzin applied PRE-broadcast was more
effective for sicklepod and morningglory control than PRE-banded. Soy
bean net returns were not significantly reduced in two of three years
in plots treated with metribuzin applied PRE-banded compared with broa
dcast application. The addition of POST or POST-directed herbicides in
creased treatment net returns over PRE-broadcast and PRE-banded metrib
uzin two of the three years of the study. No significant soybean injur
y was observed.
