Abstract

Foliar applications of oxamyl prevented nematodes from invading roots of diploid bananas. One spray with 1,250 [mu]g/ml was more effective than 1, 2, or 3 sprays with 625 [mu]g/ml applied at 5-day intervals. After 3 sprays with 1,250 [mu]g/ml, invasion may be prevented for up to 4 weeks and possibly longer. Washing roots after oxamyl treatments prevented nematicidal control. When applied to nematode-infected plants, three sprays of oxamyl decreased nematode populations in the roots. Key Words: VydateÖ, Musa acuntinata malaccensis, Radopholus similis, Helicotylenchus multicinctus, Rotylenchulus reniformis, chemical control.
