Carbofuran transfer and persistence in drained agricultural soils related to their structure and adsorption properties.
Carbofuran (Curater 5G) behavior was studied in two drained cornfield soils, clay and loamy-clay, for 2 successive years. Different dissipations were observed in each soil for the same time period (8 weeks in 1985, 9 weeks in 1986). The authors found drained water from organic mater-rich soil to possess a higher carbofuran content, with 7.1-13.7 and 2.5-5.0% of the applied dose for clay and loamy-clay soils, respectively. The major part of these percentages arose from the drained waters associated with rainfall occurring during the first 2-3 weeks after application. Laboratory experiments confirmed the influence of the soil structure and its properties on carbofuran adsorption, and consequently on carbofuran leaching under field conditions.
