Technical Abstract: Residue management can affect pest populations in cotton (Gossypium hirustum L.) and may impact optimal pest management strategies. Our objective was to determine the effect of aldicarb on cotton under different residue types and tillage regimes. Treatments in the study were residue type [continuous cotton, continuous cotton with a rye (Secale cereale L.) winter cover crop, and cotton rotated with corn (Zea mays L.)], tillage (conventional and conservation), and aldicarb (0 and 1.2 kg a.i. ha-1). Data were collected in 1998, 2000, and 2002. Residue types differed for early season thrips (Frankliniella sp.) damage only in 2002, where cotton following rye had less damage than cotton following the other two residue types. Both conservation tillage and aldicarb application resulted in reduced thrips damage to cotton plants. Nematode populations were not uniformly distributed across the experimental area. Residue type affected lint yield only in 2002 where the effect of aldicarb on cotton yield following rye was less than for the other two residue types. Lint yields were higher for conservation tillage than for conventional tillage each year, but the tillage X aldicarb interaction was not significant for yield in any year. Lint yields were increased with aldicarb only in 1998 and 2002.
