WebbAbstract : Fifty four plant species and varieties in the rice-growing areas at Kafr-El-Sheikh, Egypt were analysed for Hirschmanniella oryzae. Nematodes were recovered from roots of 8 weed species. Species of Gramineae and Cyperaceae harboured the highest nematode populations. http://ir.lib.seu.ac.lk/bitstream/123456789/6615/1/SLJoT_2024_Sp_Issue_012.pdf
