Among fungi, species of the genus Paecilomyces are considered as promising biological control agents with high potential to reduce root-knot nematode (RKN) and other nematode populations. In this research we investigated a soil hyphomycetes, Paecilomyces marquandii and its pathogenicity on eggs of RKN in vitro. In greenhouse test, root weight, plant length, fresh weight and dry weight of plants, gall index and proportion of infected eggs were determined. P. marquandii, effectively promoted growth of plants inoculated with M. incognita by suppressing its pathogenesis as root galling and reducing egg mass production. At 25 °C, a great number of nematode eggs were parasitized by P. marquandii, inhibiting juvenile development.
