“…The damping‐off caused by P. aphanidermatum was significantly controlled by treating the seeds with T. harzianum , B. subtilis , P. fluorescens , B. cereus and T. virens during the present studies. These results corroborate well with the results of many researchers . Trichoderma harzianum and Bacillus subtilis can effectively protect plants against Pythium root rot disease on cucumber, sugarbeet and cauliflower .…”

“…These parameters have been reported in C. annuum and C. chinense when the use of Trichoderma is implemented (Deshmukh et al, 2012;. This growth promoting effect in seedlings was also reported in C. annuum with T. virens-TVC 3 , where the seedlings presented greater height (69.76%) and longer roots (27.17%) (Muthukumar et al, 2011), while T. harzianum promoted higher fresh (29.05%) and dry shoot biomass (53.92%) (Deshmukh et al, 2012). In vegetables such as Lactuca sativa, Trichoderma spp.…”

The Trichoderma species act as plant symbionts, decomposers of organic material, and as antagonists of root phytoparasites. To estimate the potential of four native strains of Trichoderma as growth promoters of Capsicum annuum L. and as biocontrol against root knot nematode Meloidogyne incognita (Kofoid and White) Chitwood, two bioassays in greenhouse were established. In one, the capacity of Trichoderma to promote initial growth of seedlings (36 d after planting, dap) was evaluated. In the other, the biocontrol of Trichoderma against M. incognita at 96 dap was also evaluated. The Trichoderma strains and the chemical fertilization treatment significantly promoted seedling growth at 36 dap (P ≤ 0.01). With respect to the control, T. atroviride promoted greater height in the seedlings, while T. atroviride, T. virens and T. harzianum-C2 increased fresh weight in roots (60.14%) and both T. atroviride and T. harzianum-C2 produced up to 82.30% more dry root biomass. In biocontrol, the control plants registered the highest damage with galling indexes of 85.50% (P ≤ 0.01). The lowest galling indexes were estimated with all the Trichoderma strains (21.60% to 35%). Trichoderma atroviride reduced egg production by 63% and the production of females by 14.36%, with respect to the oxamyl nematicide. Biocontrol of the nematode through the application of the Trichoderma strains favored growth of the plants in general. The fungal species studied show potential as growth promoting agents and as biocontrol agents M. incognita in C. annuum.

“…Also, a single strain may not grow equally well in a variety of environmental conditions (Fukui et al 1994). Similarly, Muthukumar et al (2008) reported that the biocontrol agent T. viride was highly compatible with P. fluorescens.…”

The efficacy of eight fungal and ten endophytic bacterial isolates were tested for their ability to inhibit the growth of Pythium aphanidermatum, the causal agent of chilli damping-off. In vitro studies revealed that Trichoderma viride (TVA) and endophytic Pseudomonas fluorescens (EBL 20-PF) showed the highest inhibition of mycelial growth (71.5%; 76.7%) of P. aphanidermatum. Both the antagonists were compatible with each other and they were tested alone and together in vivo for the control of P. aphanidermatum. Besides, the induction of defenserelated enzymes such as peroxidase (PO), polyphenoloxidase (PPO), phenylalanine ammonia-lyase (PAL), PR-protein like b-1, 3-glucanase and the accumulation of phenolics in chilli seedlings due to the application of bioagents were also studied. Combined application of talcbased formulation of bio-agents and challenge inoculated with P. aphanidermatum recorded maximum induction of defense-related enzymes, PR-proteins and accumulation of phenolics compared with individual application. This study suggest that the increased induction of defense-related enzymes (four to fivefold) and phenolic content (sixfold) due to the combination treatment of bioagents might have involved in the reduction of damping-off incidence and in turn increased the plant growth and yield of chilli.
