Abstract
A total of 60 samples were collected from cabbage viz., Quisto, Priyadharshini, Golden Acre and Maha Rani at a depth of 10–15 cm. The soil samples were analyzed by using modified Baermann's funnel technique and the root samples were analyzed by using Acid fuschin lactophenol solution for identification of females. The survey revealed that, the root knot nematode, Meloidogyne incognita, lesion nematode, Pratylenchus penetrans, spiral nematode, Helicotylenchus dihystera, lance nematode, Hoplolaimus indicus, dagger nematode, Xiphinema americanum and Tylenchus filiformis were encountered in the samples. Among the districts, the highest incidence of damage by M. incognita was observed in Krishnagiri followed by The Nilgiris and Coimbatore districts. The maximum population (262.48/250cc soil) and minimum population (72.93/250cc soil) was observed in Krishnagiri and Theni districts, respectively.
