The impacts of two post-treatment irrigation timings on the field efficacy and residual activity of deltamethrin against nymphs of the southern mole cricket, Scaptericus vicinus Giglio-Tos, and the tawny mole cricket, S. borellii Scudder, as well as movement of deltamethrin in the turfgrass profile, were investigated in 1998. Deltamethrin followed by irrigation 24 h after treatment provided the best mole cricket control versus immediate irrigation in both field and greenhouse studies. Regardless of irrigation timing, grass clippings had the highest residual levels of deltamethrin followed by the thatch layer. Clipping residues were higher with post 24 h irrigation than immediate irrigation with few residues in the upper soil profile (top 5 cm).
