Summary Measurement of the root lengths of pre‐ger‐minated oat seedlings ( Avena sativa L. var. Sioux) grown in the dark in treated soils was used to assay residues of diclofop acid (2‐[4‐(2,4‐dichloro‐phenoxy)phenoxy]propionate) and sethoxydim (2‐[1‐(ethoxyimino)‐butyl]‐5‐[2‐(ethylthio)‐propy]‐3‐hydroxy‐2‐cyclohexene‐1‐one). Similar measurements involving maize seedlings ( Zea Mays L. var. Sunny Vee) were also used to determine residues of the herbicide chlorsulfuron (2‐chloro‐ N ‐[(4‐methoxy‐6‐methyl‐1,3,5‐triazin‐2‐yl)aminocarbony]benzenesulfonamide) in soils. The procedure appeared to be reproducible with residues of chlorsulfuron, diclofop acid and sethoxydim being detectable at amounts of 0.001, 0.2 and 0.05 μg g −1 respectively.
