Comportamento dos herbicidas atrazina e alaclor aplicados em solo preparado para o cultivo de cana-de-açucar

Abstract

Atrazine and alachlor herbicides are widely and extensively used in agriculture for the control of a variety of weeds. These herbicides are quite mobile in soil and there is a concern that they may contaminate the environment, specially surface and ground water and soils. The results suggest that alachlor and atrazine present similar behavior in the environment, but alaclhor dissipates with greater rate.
