Relationship Between Nematode Populations and Corm Rot in 'Bun Long' Taro Production

There is not a clear relationship, however, between rot and nematodes (see Fig. 2). Fifty percent of the rotted corm samples were infected with less than 49 nematodes per 250 cc of soil. Fifty percent of the samples that were not rotted were infected with more than 250 nematodes per 250 cc of soil. Thirty-one percent of the rotted samples recorded zero nematode infestation. Nine percent of the nonrotted samples recorded zero percent infestations. Introduction
