Deslocamento miscível do inseticida-nematicida sulfona de aldicarbe em solos de regiões produtoras de batata no estado de Minas Gerais.

Abstract

With the objectives to avaiable the fate of insecticide aldicarb sulfone in soil and obtain the equation parameters of dispersive-convective model for describing pesticide mobility, column of soil were confectioned with disturbed soil samples from the main potato growing regions in the state of Minas Gerais, Brazil. The experiment was mainly based on movement of solutions at steady-state conditions, for the concentration range recommended by the manufacturer. The effluent of the soil columns were analyzed by gas chromatography techniques. The results obtained allowed to check the eficience of dispersive-convective equation model to describe a mobility of product of soil, beyond of verify the low sorption of metabolic, which to propose factors of retardament close to 1,0 and high slopes of breakthrough curves.
