Efficiency of luminescent mushroom, Neonothopanus nambi for controlling root-knot nematodes (Meloidogyne incognita Chitwood) in tomatoes

Abstract

       The objective of this research was to examine the efficiency of spawn or bio-product from 2 isolates (KKU2 and PW2) of luminescent mushroom (Neonothopanus nambi) for controlling root-knot nematodes (Meloidogyne incognita) on tomato under greenhouse condition.  The high potential biological control agent was isolate PW2, when applied with culture filtrate of 30 ml/pot and spawn of 30 g/pot 10 days before inoculation with nematode eggs showed root gall reduction of 1.50 and 1.00%, respectively and 139.70 and 170.71 infective larvae per 1 g of roots. The lowest infective larvae count (74.14), was obtained from combined treatments of culture filtrate (15 ml/pot) and spawn (15 g/pot), while the control treatment showed 1,036 infective larvae per 1 g of roots.
