Summary

Four dichloroacetamide herbicide safeners (AD-67, benoxacor, dichlormid, and furilazole) and two co-applied herbicides (acetochlor and metolachlor) were measured in water samples from 7 streams across Iowa and Illinois. Iowa water samples were collected from March 2016 to June 2017, and Illinois water samples were collected from September 2016 to June 2017. The compounds studied are applied to corn, and Iowa and Illinois are the two largest corn producing states in the U.S. The seven stream sites are all adjacent to agricultural fields in corn production. Water samples (1-L) were collected in amber glass bottles using a grab or depth weighted approach. With the exception of one site, Iowa River at Wapello (USGS Site ID 05465500), all [...]

Purpose

The purpose of the data collection was to document off-field transport of dichloroacetamide safeners to streams and to document the temporal conditions under which transport is enhanced. This data set is the first to document such transport, and this data set can be used to direct future toxicity and ecological studies focused on herbicides and herbicide safeners.
