Introduction: Root-knot nematode (Meloidogyne javanica) is considered as one of the limiting factors in the cultivation of greenhouse crops, including tomatoes. This research was conducted to investigate the effect of rosemary and ferula extracts compared to chemical nematicides of rugby and volum to find an environmentally friendly method for disease management. Materials and Methods: The effect of rosemary and ferula extracts with rugby and volum nematicides on tomato root-knot nematode was investigated in a completely randomized design under greenhouse conditions. Seedlings of Mobil variety were inoculated with second instar larvae of M. javanica at the 4-6 leaf stage and the effects of plants extracts and nematicides were investigated. After 60 days, the plants were removed from the pot and their growth indicators and disease severity were measured. Results: The simultaneous use of rosemary and ferula extracts had the greatest effect in reducing pathogenicity indicators such as gall index, number of larvae and number of eggs and increasing plant growth indicators such as fresh and dry weight of root and fresh weight of stem compared to control infected with nematode and nematicides treatments. Conclusion: The good effect of the combination of ferula and rosemary extracts compared to chemical nematicides shows the appropriate potential of its use as an environmentally friendly method for disease management.
