Degradation And Persistence of Carbofuran in Soils.

Abstract

Degradation and persistance of Cerbefuran in soils were determined by adding 100ppm of Carbofuran to solls and incubating them under finnded and field capacity moisture conditions. The degradation reaction rate constant 'k' and half-life values t for the 4 soils ware computed from the amounts of Carboturan remaining in soils at different parinda.Parsistence of Carbofuran was higher in soils at field capacity moisture level than under finnded condition. Laterite soil recorded a longer persistence while the black solle registered the lasst. The half-life values were highest in isterite soils followed sequentially by alluvial, red and black soils. Higher content of organic matter and low pH of the taverite soil were resnansible for the longer persistence of Carbofuran in them, while the higher rate of degradation and lassar persistence in black, red and alluvial soils could be artributed to the heavy texture, high pH and low organic matter contents. The rate of degradation followed a logarithmic pattern indicating that the process obeyed first order Kinetics.
