Abstract

Castorbeans (Ricinus communis L.) are extremely tolerant of the rotary hoe. Its timely use plus cultivation gave effective weed control in castorbeans. The preemergence herbicides, used either alone or in combination, that appeared most promising for selective control of weeds in castorbeans were: 2-chloro-N,N-diallylacetamide (CDAA), dimethyl-2,3,5,6-tetrachloroterephthalic acid (DCPA), ethyl N,N-dipropylthiolcarbamate (EPTC), N-1-naphthylphthalamic acid (NPA), 2,6-dinitro-N,N-dipropyl-alpha, alpha, alpha-trifluoro-p-toluidine (trifluralin), and propyl dipropylthiolcarbamate (R-1607). The most dependable weed control practice in castorbeans was the use of preemergence herbicides in combination with rotary hoeings plus cultivation.
