Published online by Cambridge University Press: 12 June 2017
Abstract
Isopropyl N-(3-chlorophenyl)carbamate (CIPC), 2-chloroallyl diethyldithiocarbamate (CDEC), ethyl N,N-di-n-propylthiolcarbamate (EPTC), sodium 2,4-dichlorophenoxyethyl sulfate (sesone), and N-1-naphthylphthalamic acid (NPA) controlled Amaranthus palmeri S. Wats., (Palmer amaranth) Echinochloa colonum (L.) Link, (junglerice) and Sorghum vulgare Pers. var. sudanense Hitchc. (sudangrass) more efficiently when applications were followed by overhead irrigation, except in a few instances where weeds were controlled regardless of the irrigation method. More CIPC, sesone, CDEC, and EPTC penetrated below ¼ inch into soils, and they penetrated deeper with overhead irrigation.
