Pesticide runoff from conventional tillage, minimum tillage, and no‐tillage cropping systems: Meta‐analysis of published North American data

open access: yesJournal of Environmental Quality, Volume 54, Issue 5, Page 913-924, September/October 2025.
Abstract Pesticide applications may soon be regulated by laws predicated on the presupposition that reducing tillage, and thereby increasing soil surface crop residue cover, decreases sorbed and soluble agrochemical losses in surface runoff and erosion.

No Simazine Residues in Pecan Nuts

open access: yesJournal of the American Society for Horticultural Science, 1967
Abstract Many pecan groves throughout the south are grazed for pasture. Simazine at 3 lb/A is recommended for pastures, but the amount of residue accumulating in pecan nuts grown in pastures treated with this herbicide is not known. In this study rates of 0, 1, 2, 4, and 8 lb/A of active Simazine was applied as a spray underneath the canopy of ...

Kinetics and Equilibrium of Simazine Sorption on Soil Colloids.

open access: yesJournal of Environmental Chemistry, 1998
Adsorption and desorption of simazine on a Hiroshima loam soil and its colloidal size fractions were studied in batch experiments. The colloidal size fractions were isolated by repeated gravity sedimentation. Two-step sorption kinetics (step I-with initially non-polluted soil and step II-with soil initially polluted during step I) were well described ...

Determination of pesticides in the source and drinking waters in Londrina, Paraná, Brazil

open access: yesSemina: Ciências Agrárias, 2019
The Brazilian agricultural model is based on the intensive use of pesticides. Once in the environment, these compounds might target hydric sources, mainly through soil lixiviation or during crop application, exposing water biota as well as humans to ...
