None of the 15 tomato cultivars was immune or resistant, 10 cultivars viz., Moneymaker, Pakit, Pasestter, Chico, Peelo, Titano, Riogrande, Savio, Shadylady and Nagina were found highly susceptible (GI=5), 3 cultivars viz., Marrchia, UC-134 and Areletta were categorized as susceptible (GI=4) while the other two cultivars viz., UAE-1and Roma were rated as moderately susceptible (GI=3). For the integrated management of M. incognita on tomato, different treatments individually and in combination were evaluated. All the treatments reduced the number of galls significantly over the control. The maximum reduction of 85.34 % in gall formation was achieved where the combination of formalin sterilized soil, organic soil amendments, nursery dip treatment and addition of antagonistic organisms were evaluated together.
