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.

Abstract


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.
