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