Abstract

Granular (Rugby 10G) and liquid (Rugby 100 ME) formulations of cadusafos were evaluated for the control of Tylenchulus semipenetrans on mature lemon trees in a commercial citrus orchard at Yuma, Arizona. Three applications of cadusafos, with 2 months between applications, at the rate of 2 g a.i./m² reduced nematode populations to undetectable levels and increased the yield and rate of fruit maturity of 'Rosenberger' lemons. Yields were increased 12,587 kg/ha with Rugby 100ME and 8,392 kg/ha with Rugby 10G. Nematode populations were suppressed for at least 12 months after the last application. Key words: cadusafos, chemical control, citrus nematode, lemon, management, Rugby, Tylenchulus semipenetrans.
