Growth promoting ability and Bioefficacy of Bacillus subtilis against powdery mildew and early blight of Tomato through Foliar Spray in pot culture studies
Basamma RH and Shripad Kulkarni
A pot culture experiment was conducted during kharif
2014 to study the efficacy and growth promoting ability of Bacillus subtilis
against powdery mildew (Leveillula taurica
) and early blight (Alternaria solani
) of tomato. Talk based formulation of B. subtilis
was sprayed four times (15, 40, 65 and 90 days after sowing) at 2, 4, 6, 8, 10g/l of water along with Pseudomonas fluorescens
and Trichoderma harzianum
at 6g/l of water. Treated (Saaf 2.5g/l) and untreated checks were also maintained in the study. The foliar spray of B. subtilis
at 10g/l recorded the least per cent disease index of powdery mildew (13.22) and early blight (11.25) and there by recorded highest number of branches (6.90), fruits (16.86), fruit weight per plant (898.76g). Whereas, untreated check was least effective with highest per cent disease index of powdery mildew (54.89) and early blight (32.22) and recorded less number of branches (3.60), fruits (11.99) and fruit weight (615.00g).
