Abstract

Fenugreek (Trigonella foenum-graecum L.) is an important vegetable, spices, fodder and green manure. India is rightly known as the land of spices. Different non systemic, systemic and ready mix fungicides were evaluated in vitro against Macrophomina phaseolina causing root rot in fenugreek. Among non systemic fungicides evaluated maximum inhibition in mycelial growth was observed in mancozeb (100%) and metiram (100%). Among the different concentrations tried, Mancozeb and Metiram gave 100 per cent inhibition at all concentration. Out of seven systemic fungicides, propiconazole found best with 95.15 per cent mycelial growth inhibition followed by carbendazim (90.14%). Propiconazole and carbendazim showed complete inhibition of mycelial growth of the test fungus at 250 and 500 ppm concentration. Among the ready mix fungicides, carbendazim + mancozeb, penflufen + trifloxystrobin and metalaxyl + mancozeb gave 100 per cent growth inhibition at all concentration

Keywords

Fenugreek, Macrophomina phaseolina, root rot, non systemic fungicides, systemic fungicides and ready mix fungicides

Conclusion

The present result indicates that mancozeb, metiram, carbendazim and propiconazole and ready mix of fungicides viz., penflufen + trifloxystrobin, carbendazim + mancozeb and metalaxyl + mancozeb were quite effective in controlling root rot. The alternate application of these chemicals reduced the risk of development of resistance in pathogen. Such information will be helpful in formulation of schedule for management of root rot
