Root–knot Nematodes (Meloidogyne incognita) suppression through Pre-colonized Arbuscular Mycorrhiza (Glomus intraradices) in Tomato-PT3
Journal Title: Scientia Agriculturae - Year 2015, Vol 12, Issue 1
Abstract
Root-knot disease poses a worldwide threat to agriculture as well as environment due to use of chemical nematicides for its management. Recently Arbuscular mycorrhiza (AM) has achieving importance as biocontrol agent for the managements of Root-knot disease. In this aspect, present study focused on the effect of Glomus intraradices against Root-knot disease of tomato (Lycopersicon esculentum) caused by Meloidogyne incognita. Observations of G. intraradices against M. incognita were taken after thirty days of M. incognita second stage juveniles (J2) inoculation on tomato roots, which were pre-colonized by G. intraradices. A significant effect was observed on most of the growth parameter in nematode inoculated G. intraradices colonized plants as compare to non colonized plants at all the three harvesting periods. G. intraradices colonized plants significantly reduced the numbers of nematode root galls, numbers of adult females (46.03 %) and numbers of eggs (64.13 %) in per egg mass were significantly lower in G. intraradices inoculated plants. The finding of present study indicates the potential of G. intraradices as a potential biocontrol tool for the management of root-knot nematodes.
