Research Papers: Effect of Different Nematicides on Banana Yields in the Windward Islands

Abstract

To control nematodes in banana, the effect of applying different dosages of different types of nematicide was compared in 4 field experiments. In one experiment, DBCP, a volatile fumigant applied at 6 monthly intervals gave better yield improvement when applied at 10 ml. per plant than did dosages of 3,4 and 5.7 ml.; in another experiment there was no yield difference between dosages of 3.3 or 15 ml. of DBCP. Granular nonvolatile nematicides were applied to plants at 4 monthly intervals; good results were obtained with phenamiphos at 2 to 3 g i.a., carbofuran at 2.5 g i.a. oxamyl at 4 g i.a. and 6 g i.a. but decreased to 3 g i.a. In general granular nematicides were as good as or better than DBCP in improving yields.
