Abstract
Metham sodium applied in Oct. through center pivot irrigation systems was evaluated for control of M. hapla at 374, 468 and 701 l/ha and for control of M. chitwoodi at 468 l/ha on potato. Metham sodium at the high rates effectively controlled M. hapla. No females were detected in the tubers at the high rates of nematicide application, whereas a mean of 19 and 69% of the tubers were infected at the low rate and in the nontreated controls, respectively. In the M. chitwoodi trial only 1.5% of the tubers in the treated plots were infected compared with 82% in the nontreated plots. Metham sodium effectively controlled M. chitwoodi to soil depths of 30, 61 and 91 cm.
