Rotylenchulus reniformis is an agricultural pest of economic and regulatory importance. The effects of irradiation on second-stage juveniles (J2) of R. reniformis were evaluated in a glasshouse bioassay. Nematodes were irradiated in an aqueous solution in plastic tubes within cored Ipomoea batatas roots. Radiation treatment doses ranged from 100 to 2000 Gy. After irradiation, nematodes were inoculated into pots containing I. batatas plants and plants were harvested after 3 months to evaluate nematode reproduction. No live R. reniformis were recovered from plants inoculated with irradiated J2 treated with a radiation dose of 300 Gy or higher. Reproductive potential was significantly reduced at radiation doses as low as 100 Gy compared with untreated controls. A radiation dose of 300 Gy should provide quarantine security for commodities infected with R. reniformis.
