In Haryana, India, only carbofuran is registered for the management of root-knot nematodes. The objective of this study was to investigate the potential of cruciferous bio-fumigants for the management of root-knot nematodes (Meloidogyne incognita) in okra. The experiments were conducted at research area Department of Nematology in 2017 to 2018 and 2018 to 2019. During this investigation, cruciferous bio-fumigants such as cabbage leaves and cauliflower leaves were used as bio-fumigant sources to protect Okra cv. Hisar Unnat. Fresh and chopped leaf mass of cabbage and cauliflower was incorporated uniformly into a naturally infested field. The initial nematode population in both years was 224 and 256 J2/200 cc soil, respectively. The results of our investigation showed that in both the years okra yield was enhanced significantly by the measures of nematode management. In addition, both of the tested bio-fumigant plants leaves proved to be potentially promising for the management of root-knot nematodes. Among the bio-fumigants, the highest decrease in nematode population, root gall index and increase in yield was observed in cabbage leaves @ 50 t/ha in both years, consecutively.
