EFFECT OF SOME INDIGENOUS ISOLATES OF Trichoderma harzianum ON ROOT KNOT NEMATODE, Meloidogyne javanica (TREUB) CHITWOOD
Soil and root samples of tomato were collected from root knot nematode-infested fields of fifteen different localities of Malakand and Swat (NWFP) Pakistan in 2006-07 and Trichoderma harzianum was isolated from these samples. These isolates were tested against Meloidogyne javanica (Treub) Chitwood in the in vitro. Isolates Th1 and Th9, collected from Jabban and Shamozai were more aggressive tha...
