Abstract ABSTRACT The research explorations on the subject entitled “Management of nematodes in brinjal (Solanum melongina L.) through ecofriendly practices†were undertaken in view of hazardous effect of chemicals on the agro-ecosystem. Out of 12 cultivars Arka Sheel and Rampur Local showed their resistant and moderately resistant reaction, respectively, while other 10 ( Arka Kusumakar, Arka Shirish, Arka Keshav, Arka Nidhi, Arka Neelkanth, Arka Anand, Surya, Gulabi, Polur Local and Pusa Purple Cluster) were rated as susceptible-highly susceptible. Phenolic contents in the root system of different cultivars were found positively correlated with root gall index/ number of females per root system. Reproduction factor (multiplication rate) of root-knot nematode (M. incognita) J 2 and spiral nematode (H. dihystera) were found decreased and increased in early transplanted crops, (early April-late April), respectively and vice-versa in late transplanted crops (early May-early June). Bare root dip treatments viz; carbosulfan (25 EC); imidacloprid (17.8 SL); dimethoate (30 EC) and oxy-demeton-methyl (25 EC) @ 0.05% (500 ppm) and 0.1% (1000 ppm) were tested with an exposure period of 30 minutes, against the nematode multiplication in brinjal field. In comparison to control, all the bare root dip treatments at both the concentrations tested were significantly effective in restricting the multiplication of the nematodes.
