Popis:	Early postemergence application of atrazine [2-chloro-4- (ethylamino)-6-(isopropylamino)-s-triazine] at 0.28 kg/ha in combination with alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl)acetanilide] at 0.42 kg/ha plus a non-toxic oil-surfactant blend gave season-long weed control in sweet corn (Zea maysL. var.rugosa‘Seneca Chief’). Bioassay with oats (Avena sativaL.) showed no detectable atrazine residue in the soil 3 months after herbicide application. In greenhouse studies, the response of Japanese millet (Echinochloa crus-galliL. Beauv. var.frumentacea) to early postemergence application of atrazine and alachlor combinations plus an oil-surfactant blend was synergistic. Soil uptake played a major role in the activity of the herbicides. Formulants used in commercial alachlor when added to atrazine spray, enhanced atrazine activity in a way similar to that of the non-toxic oil-surfactant.
