Effect of different bioinoculants, organic amendments and pesticides on the management of Meloidogyne incognita-Fusarium solani disease complex on tomato cv. K-25

Studies were made to determine the effect of bioinoculants viz. Pseudomonas fluorescens, Aspergillus niger, Trichoderma harzianum, T. virens and Paecilomyces lilacinus @ 50 kg/ha (2×10⁸ cfu/g) each; organic amendments viz. fresh chopped neem (Azadirachta indica) and murraya (Murraya koenigii) leaves @ 3.0 q/ha each, farm yard manure and mint (Mentha arvensis) manure @ 15 q/ha each, neem seed powder @ 1 q/ha and pesticides viz. carbofuran 3G (Furadan) and topsin-M 75 WP (Thiophanate methyl) @ 2.0 kg a.i./ha each for the management of Meloidogyne incognita- Fusarium solani (@ 2000 J₂ larvae and 7 g fungal culture having 10⁶ cfu/g culture per 4 kg soil respectively) disease complex of tomato cv. K-25 under pot conditions. Results revealed that all the treatments significantly improved the number of fruits, fruit weight, length, fresh and dry weight of plants. T. harzianum was found superior among all the treatments in improving fruit weight and plant growth followed by P. fluorescens, carbofuran, A. niger, T. virens, A. indica seed powder, topsin- M, P. lilacinus, A. indica leaves, M. koenigii leaves, M. arvensis manure and farmyard manure respectively. Highest root-knot index (2.6) and fungal infection (50%) was observed in untreated plants. Carbofuran was found highly effective against M. incognita, topsin-M against F. solani and T.harzianum was effective against both the pathogens.
