Title: Contamination of groundwater by triazines, metolachlor and alachlor
Abstract: The movement of triazines (atrazine, simazine, cyanazine), metolachlor and alachlor were studied in continous irrigated corn in an Evesboro loamy sand soil. Both no-tillage and conventional tillage treatments were used. Atrazine and simazine were detected in the groundwater more frequently than cyanazine and metolachlor. Alachlor, atrazine and simazine moved rapidly to the groundwater if sufficient rainfall occurred shortly after they were applied. Alachlor concentrations ranged from 4.0 to 15.0 ppb and atrazine concentrations ranged from <1.0 to 54 ppb. Metachlor was detected in the groundwater more frequently than cyanazine. Metolachlor concentrations range from < 1.0 to 12.0 ppb and cyanzaine concentrations ranged from < 1.0 to 29.0 ppb. There was no large differences in pesticide movement between conventional tillage and no-tillage.
