Abstract

A field experiment was conducted in Coimbatore district to study the efficacy of the biocontrol agent Pseudomonas fluorescens for the management of root-knot nematode Meloidogyne incognita in tomato. Soil application of the native isolates Pft 20 @ 2.5 kg/ha significantly reduced the nematode infestation in all the bacterized plants both in soil and roots with the least number of adult females, number of egg masses, number of eggs per egg mass and gall index and besides increased the plant growth, total soluble sugars and lycopene content of the fruit.

Keywords: Pseudomonas fluorescens, Meloidogyne incognita, tomato.
