Effect of conventional vs. No-tillage on pesticide leaching to shallow groundwater
Atrazine was found in groundwater all year, while cyanazine, alachlor, and carbofuran were present only for a short period (<3 mo) after pesticide application. Fairly constant background levels ofExpand
Atrazine and simazine movement to Wye River estuary
La quantite totale d'herbicide atteignant l'estuaire depend de la quantite d'herbicide utilisee dans le bassin et de la duree du ruissellement par rapport aux dates d'application de l'herbicide
Impact of tillage practice on runoff and pesticide transport
ABSTRACT: A two-year study was conducted to evaluate the effect of no-till (NT) and conventional-till (a corn production practices on pesticide loss in runoff from natural rainfall. Runoff from twoExpand
Influence of hairy vetch residue on atrazine and metolachlor soil solution concentration and weed emergence
Abstract High levels of cover-crop residue can suppress weed emergence and also can intercept preemergence herbicides and potentially reduce their effectiveness. This research was conducted inExpand
ABSTRACT A three-year field study was initiated in 1986 to determine the impact of tillage practice, mode of pesticide application, and pesticide formulation on chemical transport The 1.28-ha fieldExpand
Behavior of trifluralin in aquatic model ecosystems
It is believed that the risks of trifluralin in the aquatic ecosystem are greatest when there is a continuous input of triblural in the soil, and with an occasional soil-incorporated input, the degradation processes would minimize this risk. Expand
Persistence and leaching of atrazine, alachlor, and cyanazine under no-tillage practices
Abstract Soil residues of atrazine, alachlor, and cyanazine were measured in no-till corn plots that had received annual herbicide applications from 1981–1985. Treatments were as paired combinationsExpand
Effects of Tillage and Rainfall on Atrazine Residue Levels in Soil
A field study was conducted in 1987 to 1991 to determine the effect of tillage and rainfall on distribution of atrazine in soil. Soil samples (10-cm increments to 50 cm) and crop residue samples wereExpand
