Abstract

Field studies were conducted in 1975 and 1976 at Urbana, Illinois, to evaluate soybeans [Glycine max (L.) Merr. ‘Amsoy 71′] as a potential rescue crop following the use of cyanazine{2-[[4-chloro-6-(ethylamino)-s-triazin-2-yl] amino]-2-methylpropionitrile} and procyazine {2-[[4-chloro-6-(cyclopropylamino)-1,3,5-triazine-2-yl] amino]-2-methylpropanenitrile} with corn (Zea mays L.). Preplant incorporated and preemergence applications of each herbicide were made at the recommended broadcast rates to Dana and Flanagan silt loams. Corn was removed and soybeans were planted 7, 13, and 21 days (1975) or 10, 15, and 23 days (1976) following herbicide application. Visual injury ratings, stands, and yields for soybeans were determined. In spite of varying degrees of visible injury and stand reductions, yields were not reduced significantly when soybeans were planted 3 weeks after cyanazine or procyazine application.
