Effect of culture filtrates of Rhizoctonia Bataticola and some saprophytic soil fungi on hatch and on mobility of root-knot nematode, Meloidogyne incognita*

The increase in concentration of culture filtrate of the tested fungi (Rhizoctonia bataticola, Alternaria alternata, Aspergillus flavus, Penicillium chrysogenum, Trichoderma viride) and period of exposure induced greater inhibition of the hatch as well as mobility of second - stage jureniles of M. incognita. Culture filtrate of T. viride at lower concentration and shorter period of exposure resluted in enhanced hatch. Amongst the fungi studied, culture filtrate of R. bataticola seems to be more potent in inhibiting the hatch as well as mobility of M. incognita.
