Study the Bioefficacy of Aqueous Formulation of Various Antagonists against M. incognita in Tomato (Solanum lycopersicum L.) under Field Condition

Field trials were conducted to assess the efficacy of biocontrol agents viz., Pseudomonas spp. and Bacillus spp. against ischolar_main knot nematode, Meloidogyne incognita in tomato (PKM1variety). The liquid formulations of six native bacterial isolates delivered through seedlings ischolar_main dip treatment @ 200 ml/ha of seedling followed by soil application through drip irrigation @ 500 ml/ha along with two standard check. The results indicated that the most of the tested treatments reduced ischolar_main galls and increased tomato plant growth characters. Pseudomonas fluorescens (Pfpv1) was most effective treatment on both ischolar_main and soil population achieving 67.17 and 59.80 per cent reduction, respectively followed by Bacillus subtilis (Bsvn11).
