Host range of the spiral nematode Helicotylenchus abunaamai
Abstract
Of the 61 plant types, belonging to 21 families, tested in replicated pot culture experiment as possible hosts of Helicotylenchus abunaamai, 38 botanical species were found to be susceptible and favourable hosts taking into consideration of multiplication of the initial level of nematode inoculum. The highest nematode population was recorded on little millet “gulji” followed by rice. The rest of the 23 plant species were unsuitable, of which 12 were regarded as poor hosts and 11 (niger, marigold, rape seed, mustard, karanja, radish, coriander, bitter gourd, knolkhol, and margosa) were graded non-hosts.
