Pathogenicity of reniform nematode (Rotylenchulus reniformis Linford and Oliveira, 1940) on ginger (Zingiber officinale rose)

Abstract

Two pot culture experiments were laid out (i) to study the pathogenic effect of different inoculum levels of R. reniforms on ginger comprising of seven treatments and four replications and (ii) to studythe relative pathogenic effect of root -knot and reniform nematodes singly or in combinations on the same crop comprising of five treatments and four replications. The duration of study was 120 days The result reveals that ginger is a good host for reniform nematode R. reniformis and it can cause pathogenic effect at a considerable extend at higher inoculum levels, within a period of 120 days.
