Abstract:
Background and Objective: The root-knot nematode, Meloidogyne incognita is a sedentary endoparasite and one of the most damaging agricultural pest attacking a wide range of crops including pulses and vegetables and Purpureocillium lilacinum is a biocontrol agent used in this study. A pot experiment was conducted to find out the nematicidal potential of a biocontrol agent, Purpureocillium lilacinum for the sustainable management of root-knot nematode, Meloidogyne incognita infecting Vigna Radiata cv. ‘PDM-139’ under glasshouse conditions. Materials and Method: Clay pots (15 cm in diameter) filled with 1 kg autoclaved soil mixed with farmyard manure in the ratio of 4:1 were treated with biocontrol agent, P. lilacinum applied at 1.5 g /pot in individual, sequential and concomitant manner. Results: All the treatments were found to significantly improve the growth and physiological parameters of mung bean and reduced the pathological parameters as compare to untreated inoculated control. The highest improvement was found in those plants treated with P. lilacinum alone. Concomitant and sequential inoculation of P. lilacinum with M. incognita also showed enhancement in growth parameters of mung bean. Least enhancement in growth parameters were observed in those plants inoculated with nematode alone. Conclusion: It may be due to the nematicidal nature of P. lilacinum against root-knot nematode, M. incognita. Hence, it may be concluded that P. lilacinum as biocontrol agent is better alternative against chemical nematicides for the sustainable management of M. incognita and reduce environmental hazards.
