Total toxic aldicarb residues in soil, cottonseed, and cotton lint following a soil treatment with the insecticide on the Texas high plains.

Aldicarb residues in soil, cottonseed, and cotton lint following an in-furrow soil application of 15 lb/acre of a 10% granular formulation of the insecticide on the Texas High Plains were investigated by a gas chromatographic-flame photometric detection procedure. Aldicarb residues (as the sulfone) as high as 1.65 ppm (average of three laboratoyies) were detected in soil from dryland fields 3 (days following application, decreasing to 0.24 ppni in 1 month and completely disappearing in 4 months.
