Ld Evaluation of Eradicator for Fire Ant Control, 1992

Abstract

To determine the efficacy of water, chlorpyrifos and permethrin as control agents when applied with the Eradicator pest control device, sixty mounds of RIFA were selected for treatment. Each mound was characterized and mapped before treatment to determine any colony movement resulting from treatments. Treatments were made using an Eradicator control device attached to a water source providing ca 40 psi (actual pressure was measured). The Eradicator is a hose end sprayer fitted with a 2.5 ft probe, open at the end, which when inserted into fire ant mounds released a stream of water and pesticide. A reservoir attached to the underside of the Eradicator held the pesticide drawn into the water stream by the venturi effect. Treatments involved the insertion of the Eradicator application probe and injection of liquid into the mound. A flow meter determined the amount of liquid injected into each mound.
