Abstract

Atrazine herbicide has been in an EPA special review since 1994 because of soil surface runoff concerns. Beginning in 1997, we evaluated atrazine and non-atrazine herbicide treatments in conventional tillage corn and no-till corn on university research farms at Clay Center (irrigated) and Lincoln, Nebraska (non-irrigated). The objective was to compare some common atrazine and non-atrazine herbicides in soil-applied and post emergence treatment combinations. Fourteen herbicide treatments were selected to represent commonly used herbicide classes and application timings. This NebFact reports the no-till results.
