Title: Residue and Efficacy Studies of Alachlor on Cabbage and Soil1
Abstract: Abstract Newly transplanted cabbage ( Brassica oleracea L. var. capitata L. f. alba DC. cv. Market Prize) was treated with alachlor [2 chloro-2′, 6′-diethyl- N -(methoxymethyl)acetanilide] at rates of 0, 3.4, and 6.7 kg/ha in 4 tests at 2 locations during 1971, 1972, and 1976. Both rates provided control of all predominant weeds, except ivyleaf morningglory, [ Ipomoea hederacea (L.) Jacq.]. Decreased crop vigor usually occurred with the high rate of alachlor. Cabbage samples from the 1976 tests contained alachlor residues below 0.01 ppm, the low detectable limit. Residue levels in soil samples from plots that received 3.4 kg/ha decreased from 0.72 to to 0.07 ppm at one location and 0.72 to 0.08 ppm at the other location during the 10 and 11 weeks of the experiment. Residues in soils from the 6.7 kg/ha plots decreased from 1.58 to 0.10 ppm and 1.89 to 0.22 ppm for each location, respectively.
