Abstract

Lentil wilt caused by Fusarium oxysporum f. sp. lentis is a significant disease and a major limiting factor for production of lentil. The present study on in vitro evaluation of fungicides and bio-agents against Fusarium oxysporum f. sp. Lentis revealed that fungicides provided better inhibition in growth of test pathogen than Trichoderma spp. Among the seven different fungicides, Thiophanate Methyl 450g/l + Pyraclostrobin 50g/l@800 ppm was recorded as best treatment which maximum inhibited the growth of test pathogen (92.60%). Tebuconazole 5.36% w/w FS when applied @800 ppm concentrations was identified another potential fungicide with 91.60% inhibition. Among the four different species of Trichoderma, T. asperellum was found most effective in inhibiting the growth of Fusarium oxysporum f. sp. lentis.

Conclusion

All the tested fungicides were significantly superior over control in inhibiting the growth of Fol. However, a combination product Thiophanate Methyl 450g/l + Pyraclostrobin 50g/l @ 800ppm exhibited maximum per cent inhibition across all the tested fungicides and concentrations. Tebuconazole 5.36% w/w FS could be identified as second-best fungicide at 800 ppm and best fungicides at all the other tested concentrations. These identified fungicides could be useful in management of Fusarium wilt of lentil. Further, among the different species of Trichoderma, T. asperellum was identified as better antagonist for Fol and can be recommended for management of Fusarium wilt in lentil and organic/ commercial cultivation of lentil.
