Efficacy of termiticide treatments to soil in field tests in the southern United States

IRG/WP 94-30043

B M Kard, J K Mauldin

In standard ground-board and concrete-slab efficacy tests in the southern United States, termiticides provide several years of subterranean termite control depending on rates applied to the soil and test site location. Years of 100% control (as of February 1994) provided by each currently marketed termiticide applied at highest label rates under concrete slabs in our four primary test sites (Florida, Arizona, Mississippi, & South Carolina) are: chlorpyrifos 1.0% (Dursban®TC, Equity®, Tenure®), 6-12 years (1971 four-site test), 21 years (1967 Mississippi test); cypermethrin 0.50% (Demon®TC, Prevail®FT), 4-11+ years; permethrin 1.0% (Dragnet®FT), 5-15+ years, (Torpedo®), 3-13+ years; fenvalerate 1.0% (Tribute®), 6-12 years; bifenthrin 0.125% (Biflex®TC), 2-7+ years.
