Studies on compatibility of avermectin with carbofuran 3G, Pseudomonas fluorescens and Trichoderma viride for the management of Meloidogyne incognita in tomato revealed that combination of seedling ischolar_main dip with avermectin 75% and soil application of carbofuran 3G @ 1kg a.i ha-1 recorded maximum shoot length of 36.90cm, fresh shoot weight of 16.80 g, dry shoot weight of 5.2g, and fruit yield of 290.50g / plant. It was followed by avermectin + P. fluorescens and avermectin + T. viride. Maximum reduction in number of M. incognita adult females (14.33), number of egg masses/g ischolar_main (6.33), number of eggs per egg mass (105.33), soil nematode population (105.67) and ischolar_main knot index (1.0) was recorded in plants treated with avermectin + carbofuran 3G, followed by combined application of avermectin with P. fluorescens or T. viride.Keywords
