Four densities of fungal spore suspension (104, 106, 108 and 1010 spores/g of soil) were calculated by hemocytometer (Booth, 1971) for each fungal species. The conidial suspension of each density for each fungus was mixed thoroughly with the soil of each pot. At the same time, the suspension of 10,000 M. javanica eggs in 5 ml water was also mixed thoroughly with the potting soil. Mixing of both inocula with the soil of each pot was done thoroughly in a plastic bag. Then, thirty-day-old tomato seedlings were transplanted immediately into the infested pots (one seedling/pot). Control treatments included untreated seedlings and nematode treated seedlings. Each treatment was replicated four times. The treatments were arranged on a greenhouse bench (24 ± 2 °C) in a randomized complete block design. Seedlings were irrigated and fertilized with a nutrient solution (1 g water soluble fertilizer N-P-K in 1 liter water) as needed till the end of the test.
