Abstract

Qualitative and quantitative oil content of corn (Zea mays L.) kernels as influenced by herbicides was measured by gas-liquid chromatography. Alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl) acetanilide] at 0 to 6.7 kg/ha, atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] at 0 to 5.6 kg/ha, linuron [3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea] at 0 to 3.4 kg/ha, prometryne [2,4-bis(isopropylamino)-6-(methylthio)-s-triazine] at 0 to 3.4 kg/ha, and cyanazine [2-[4-chloro-6-(ethylamino)-s-triazine-2-yl]amino-2-methylpropionitrile] at 0 to 7.8 kg/ha were evaluated. Oil quantity was not greatly influenced by any of the herbicides; however, percentage corn oil fatty acid composition was altered to a minor but statistically significant degree by each of the herbicides. The use of alachlor, cyanazine, atrazine, linuron, or prometryne on corn at recommended rates or at rates greater than currently recommended field application rates did not induce serious changes in either total oil content or fatty acid distribution in corn.
