Optimization of Dosages of Biocontrol agents for the Management of Root knot nematode, Meloidogyne incognita in Ridgegourd and Snakegourd

Field trials were conducted to optimize the dosage of biocontrol agents for the management of root knot nematode, Meloidogyne incognita in ridgegourd and snakegourd. The trials were conducted in a randomized block design during June and July for subsequent years (2013-14) with seven treatments and four replications. The results revealed that among the different dosages of application, seed treatment with P. fluorescens @ 50g/kg of seed was found effective, which recorded 15.2 t/ha with 58.3% increase in yield and 52.3% reduction in nematode population followed by seed treatment with T.viride @ 50g/kg seed, which showed 14.5 t/ha with 51.0% increase in yield and 50.0% reduction in nematode population.
