Abstract: 

Nematode species infected with Pasturia penetran were founed in 5 out of 55 root and soil samples coIlected from various regions of Iran. The bacterial isolates recovered from Meloidogyne javanica from Ahwas (isolate PA), M. javanica from Saravan (isolate PS), M. javanica from Varamin (isolate PV), Helicotylenchus pseudorobustus from Ardestan H. vulgans and Amplimerlinius macrurus from Golpayegan. They were on the basis of morphological features of endospores and characteristics of the vegetative stages identified as Pasturia penetrans.
The efficacy of P. penetrans isolates PA and PNG (an isolate received from New Guinea) in controlIing M. javanica infection on tomato plants was evaluated under greenhouse conditions.
PA and PNG at a density of 105 spores/g.soil and Nemacure (fenamifos, as check) at 4µg/g.Soil were added separately to 500 g soil in pots infested with 4000, eggs of M. javanica. One tomato cv. Rutgers seedling was trans planted in each pot. The isolates PA and PNG and Nemacure reduced population of M. javanica by 71%, 87.1% and 79.8% respectively. Difference between the treatments were not statistically significant.
