Abstract

A simple method to mass multiply Pasteuria penetrans (Thorne) Sayre&Starr an obligate parasite of plant parasitic nematodes, was worked out by modifying the method defined by Stirling and Wachtel (1980). With the increase in seed rate/pot, there was an increase in root content/pot and number of Meloidogyne incognita (Kofoide&White) Chitwood females which in turn contributed to an increase in number of infected females and spore number/g root. This method not only enhanced spore production efficiency/pot but also reduced the inherent disadvantage of maintaining and handling a large number of plants under individual pot (in vivo) conditions.
