Studying the Separate and Integrated Application of Fungus, Trichoderma harzianum i2375 and Vermicompost in Control of Root-knot Nematode, Meloidogyne javanica, on Tomato

In the present study, Integrated and separate application of Trichoderma harzianum i2375 and vermicompost on the control of root-knot nematode Meloidogyne javanica was examined under greenhouse conditions on tomato. Root-knot nematode and fungal isolate identified using morphological characters. In the green house experiment, effects of integrated and separate application of vermicompost and T. harzianum i2375 on tomato plants growth factors and nematode population, in two independent of 90 and 120 days in spring season were tested. Results indicated that integrated application of both the agents not only controlled the target nematode but also enhanced growth parameters of the host plant including fresh weight and length of tomato upper portion which shows the ability of integrated application of these two bio-agents. The number of galls in the application of the integrated treatment was the least and the nematode population in the green-house conditions was up to 78.6% with the use of integrated Trichoderma and vermicompost, which was significant in comparison with the control at 5% level. Kind of the treatment with reference to the nematode percentage control indicates key role of using of the fungal isolate along with the vermicompost in reducing nematode infection and population indices.
