Abstract

Three methods of applying insecticides for the control of the wireworm, <i>Agriotes obscurus</i> L.. were tested using fonofos and terbufos. Most treatments gave significantly more marketable tubers than the control. The furrow treatment gave more consistent results than broadcast or side-dress and, at 1.1 or 2.2 kg a.i/ha, gave control equal to, or better than, the broadcast treatment at 5.6 kg a.i./ha. Analyses by gas chromatography using a flame photometric detector for residues in potatoes grown in treated soil showed residues to be less than 0.02 ppm.
