Abstract

Herbicides incubated in Wymore silty clay loam soil at field capacity at 15, 25, and 35 C showed 3-amino-2,5 dichlorobenzoic acid (amiben) the most persistent, 2,3,6-trichlorobenzoic acid (2,3,6-TBA) intermediate, and 2-chloro-4-ethylamino-6-isopropylamino-5-triazine (atrazine) the least persistent to microbial and/or chemical breakdown. All herbicides persisted much longer at 15 C than at 35 C. The average annual temperature below the plow layer is about 12 C. This helps explain the persistence of leached herbicides under field conditions.
