Abstract

The fate of 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea (linuron) in greenhouse-grown juvenile corn (Zea mays L., var. N. J. 9), soybean (Glycine max (L.) Merr., var. Kent), and crabgrass (Digitaria sanguinalis (L.) Scop.) was investigated. Linuron entered the plants from nutrient solution with the water absorbed. A small but measurable amount of the herbicide was found in the tissue as 3-(3,4-dichlorophenyl)-1-methoxyurea and as 3,4-dichloroaniline. A materials balance between linuron uptake and acetone extractable linuron plus metabolites found could not be achieved. Evidence is presented for the presence of “bound” linuron which accounted for from 15 to 25% of the herbicide absorbed.
