Wj. Grichar, CONTROL OF PALMER AMARANTH (AMARANTHUS-PALMERI) IN PEANUT (ARACHIS-HYPOGAEA) WITH POSTEMERGENCE HERBICIDES, Weed technology, 11(4), 1997, pp. 739-743
Seven postemergence (POST) herbicides were evaluated alone and in vari
ous mixtures for Palmer amaranth control in peanut from 1992 through 1
994. AC 263,222 at rates as low as 0.04 kg/ha controlled greater than
or equal to 95% Palmer amaranth. Imazethapyr at rates of 0.05 to 0.07
kg/ha controlled greater than or equal to 90% Palmer amaranth in 2 of
3 yr. Acifluorfen alone or in combination with bentazon or 2,4-DB and
lactofen alone controlled > 90% Palmer amaranth in 2 of 3 yr. Bentazon
or pyridate failed to provide adequate control (less than or equal to
60%), while 2,4-DB provided good control (80%) in only 1 of 3 yr.
