Abstract
Foliar applications of oxamyl prevented nematodes [Radopholus similis, Helicotylenchus multicinctus, Rotylenchulus reniformis] from invading roots of diploid bananas [Musa acuminata malaccensis]. One spray with 1250 .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 1250 .mu.g/ml, invasion may be prevented for up to 4 wk and possibly longer. Washing roots after oxamyl treatments prevented nematicidal control. When applied to nematode-infected plants, 3 sprays of oxamyl decreased nematode populations in the roots.
