EFFECT OF SOME INDIGENOUS PLANT EXTRACTS ON THE INHIBITION OF EGG HATCHING OF NEMATODE Meloidogyne incognita Chitwood INFESTING MULBERRY

Root knot disease caused by the nematode Meloidogyne incognita is one of the major diseases of Mulberry, Morus spp. which causes major reduction in yield affecting both quality as well as quantity of leaves and fruits. Plants produce a high diversity of secondary metabolites for self defense and survival in their habitat. Some of the plants are known to be inhibiting the development of the nematodes. The present study was carried out to screen the locally available plants for their nematicidal activity. Twelve plants species were selected and methanol extracts with different concentrations (25, 50, 75 and 100%) of different plants were tested for inhibition of hatching of M. incognita egg and juvenile mortality in different durations. The plant extracts of Neem, Clitoria ternatea and Passiflora foetida were recorded to be highly effective for inhibition of hatching of egg and increasing juvenile mortality of M. incognita. Which will be immense helpful to re duce the qualitative and quantitative loss of mulberry leaf and fruit with eco-friendly plant extract.
