Abstract:
A survey was conducted for the collection of Trichoderma spp in different districts of major tomato growing areas of Tamil Nadu viz., Allanganallur, Checkanurani, Natham, Poonjuthi, Sirumalai, Andipatti and Pavoorchathiram. Fiveteen isolates of Trichoderma spp were isolated from the rhizosphere soil of tomato. These isolates were screened against southern blight pathogens. Among the fourteen isolates tested, the isolate TV22B had maximum inhibition of 83.33 per cent inhibition over control and with mean mycelial growth of Sclerotium rolfsii of 1.50 cm under in vitro. Minimum per cent inhibition over control was recorded by TV1313M with 36.44 per cent and mean mycelial growth of 5.72 cm.
