Abstract

Tolerance of corn (Zea mays L. ‘B’), cotton (Gossypium hirsutum L. ‘coker 413’), soybean (Glycine max Merr. ‘Hardee’), turnip (Brassica rapa L. ‘Tendergreen’), sorghum (Sorghum bicolor (L.) Moench. ‘Georgia 615’), purple nutsedge (Cyperus rotundus L.), yellow nutsedge (C. esculentus L.), and johnsongrass (Sorghum halepense (L.) Pers.) to 2,6-dichlorobenzonitrile (dichlobenil) at 0, 0.14, 0.28, 0.56, 1.12, and 2.24 kg/ha in four Georgia soils was determined. Equivalent rates of dichlobenil generally were more toxic in Davidson clay loam which had the highest clay content. Crop tolerance was corn > sorghum > cotton > turnip. Purple and yellow nutsedge tolerance to dichlobenil was intermediate to that of the crops tested. Johnsongrass response was equivalent to that shown by sorghum.
