Accumulation pattern and insecticidal effect of aldicarb in cotton following soil treatment for the control of the tobacco whitefly (Bemisia tabaci)

The accumulation pattern of the pesticide aldicarb (2-methyl-2-(methylthio) propionaldehyde O-(methylcarbamoyl)-oxime) and of its sulfoxide and sulfone metabolites was studied in field-grown cotton, following soil treatments at various intervals from planting. Control of the tobacco whitefly (Bemisi...

Description
Summary:The accumulation pattern of the pesticide aldicarb (2-methyl-2-(methylthio) propionaldehyde O-(methylcarbamoyl)-oxime) and of its sulfoxide and sulfone metabolites was studied in field-grown cotton, following soil treatments at various intervals from planting. Control of the tobacco whitefly (Bemisia tabaci ) was determined and correlated with the concentration of aldicarb and of its metabolites in cotton leaves. The main constituent found in the leaves was aldicarb sulfoxide, which reached its maximum concentration there at about 22 days post-treatment. Late application of the insecticide (mid-July) resulted in higher concentrations toward the end of the growing season and so gave improved control of the pest. Results are presented for residues in young and mature leaves and in the seeds.
