Evaluation of Bio-Nematicides against the development of Root Knot Nematode (Meloidogyne incognita) in Tomato

Root knot nematodes(Meloidogyne spp.) are the major constraints for vegetable crop production in Pakistan. Objective of the present study was to determine the efficacy of most effective of bio-product (Vampire, Axiom, Fline) at 5% concentration on the invasion and development of root knot nematode by seed dip and seedling treatment. Nematode reproduction and their influence on plant growth were determined after 60 days. At harvest of data on population of J2 penetration and development, final J2 population in roots and soil, number of females/ gm of soil, root galling and egg masses was assessed on 0-5 scale. Vampire and Fline @ 5% showed best control of root knot nematode after 60 days(No. of root galls/root system) 50B,20B means value as compared to control 106A at seed dip treatment. similarly, Vampire and Fline @ 5% showed best control of root knot nematode after 60 days(No. of root galls/root system) 31B,08B means value as compared to control 102A at seedling treatment. These bio-product are seems to be the best in seed treatments as well as in seedling dip treatments economically.
