ABSTRACT
Under greenhouse conditions, cassava wastewater (manipueira) concentrations of 25, 50 and 100%, as well as two immersion periods (9 and 12 h), besides a control, were evaluated for the treatment of yam seed tubers naturally infected by Scutellonema bradys and Pratylenchus coffeae. Tuber sprouting percentage at three months after planting was 100% for all treatments. At five months, manipueira concentrations in both immersion periods (25% - 9 hours; 25% and 50% -12 hours) led to the best results, compared to control, for the final populations of nematodes/g tuber peel.
