Role of plant growth promoting microbes in the control of fungal foliar diseases of tomato under protected cultivation

Abstract Background This study was conducted to assess the effectiveness of plant growth-promoting microbes on foliar disease organic tomatoes under protected cultivation. The biological control agents, viz., Trichoderma harzianum ( T. ), Bacillus subtilis B. and Pseudomonas fluorescens P. ) , used seed treatment, seedling dip, spray separately in sequence with plot size (2.5 × 1 m) spacing (45 60 cm). observations percentage yield growth parameters were assessed, economics calculated. Tukey's HSD at p < 0.05 compare all means among treatments. Results results showed that treatment 5 g, followed by a dip 10 g l −1 four times 15 days intervals significantly 0.05) reduced tomato diseases early blight, septoria leaf spot, powdery mildew T 2). These comparable treated dipping spraying 15-day 3). Except for 1, parameters, yields, net returns, benefits higher than untreated 8). Conclusion applications as had considerable scope managing fungal (multiple) achieving sustainable yields cultivation organically grown tomatoes.
