Isolates of Trichoderma (T. harzianum TR20 and T. pseudokoningii TR17) and fluorescent pseudomonads (Pseudomonas fluorescens P28 and P51) were evaluated (alone and in combination) under greenhouse and field conditions for efficacy in suppressing rhizoctonia root rot incidence and promoting plant growth in chilli. The combination, T. harzianum (TR20) + P. fluorescens (P28), was most effective in reducing disease incidence (66.7% more efficient than the control), but was at par with copper oxychloride (0.3%). Highest per plant yield also was recorded in the treatment combination TR20 + P28, followed by T. pseudokoningii (TR17) + P. fluorescens (P51). T. pseudokoningii (TR17) and T. harzianum (TR20) when applied alone also significantly increased the yield per plant and was superior to both the pseudomonads applied individually.Downloads
