The effect of the systemic nematicide-insecticide oxamyl in the control of the nematodes of bananas was evaluated in two field experiments at Rincon and Santa Isabel, Puerto Rico. The material was applied to the soil at the base of the plant and to the leaf axil with the Phillips(?) 20 ml Automatic Drencher Mk III (Spot Gun). In both localities, three doses of the undiluted product per plant were used: 2.5, 5.0 and 10.0 cm in four applications during the growing season; two in autumn and two in summer, each set of two applications at a 30 day interval. Nematicide applications were always made one or two days after rain or furrow irrigation. At Rincon the Valery variety was used and at Santa Isabel the Giant Cavendish. A balanced incomplete block design with 7 treatments replicated 6 times and 10 plants per plot was used. The most important nematode species present in each locality were: Radopholus similis, Pratylenchus coffeae, Meloidogyne incognita, Rotylenchulus reniformis, and Hel
