Abstract

Seven systemic nematicides were applied to bananas infected by Helicotylenchus multicinctus in two experiments. Nematode numbers were counted from root samples taken 6 mo. after the initial and 5 mo. after the second application in experiment 1, and 5 mo. after application in experiment 2. Optimal dose rates for the chemicals were determined. AC 64475 was the most active chemical, providing effective control for 5 months at 1,5 g a.i. per mat. Ethoprop at 2,0 g, aldicarb at 2,5 g and oxamyl at 3,0 g a.i. per mat also provided effective control. Phenamiphosafter single applications of 2,4 g and 3,0 g a.i. per mat was ineffective but the second application at 2,4 g a.i. per mat in experiment 1 was effective.
