“…Similarly, Ramesh (2004) reported that T. viride (TV-2) was the most effective in inhibiting the mycelial growth of P. aphanidermatum causing damping-off of brinjal. Ushamalini et al (2008) reported that the fungal antagonist T. viride inhibited the growth of P. aphanidermatum in turmeric. The inhibitory effect of T. viride against P. aphanidermatum might be due to the production of antibiotic substances includes viridin, gliotoxin, glioviridin, dermin and trichodermin (Eziashi et al 2007;Ghildiyal and Pandey 2008).…”

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.

“…Similarly, T. viride inhibited the growth of P. aphanidermatum in tomato (16); in turmeric (33) and many hosts (21). Volatile and non volatile antibiotics produced by T. viride and mycoparasitism might be responsible for the suppression of P. aphanidermatum leading to lysis (7,8,10 (29,34).…”

Damping-off of chilli caused by Pythium aphanidermatum is a major nursery disease in vegetables. In vitro experiments evaluated the effect of eight isolates of Trichoderma species (from chilli rhizosphere) were tested against P. aphanidermatum. All the Trichoderma species had varied antagonistic effects against the pathogen. Among them, TVC 3 recorded maximum growth inhibition of P. aphanidermatum and produced more amounts of volatile and non-volatile metabolites. The culture filtrate of the Trichoderma isolate TVC 3 recorded complete inhibition on the mycelial growth of pathogen at 15% concentration. Moreover, chilli seeds treated with culture filtrate of the isolate TVC 3 recorded maximum germination percentage, shoot length, root length and vigour index of chilli. The study identified the Trichoderma isolate (TVC 3 ) performed well in inhibiting the mycelial growth of pathogen as well as increased the plant growth in chilli.

“…Since this ruins the whole plant, flex sensor is chosen to monitor the finger growth. And hence turmeric finger Rhizome rot disease can be identified at the early stage and required action (applying Pseudomonas and viride) to be taken [13,14]. Pseudomonas and viride are the best natural biopesticides [13] for many plant diseases.…”

Modern agribusiness is becoming increasingly reliant on computer-based systems which was formerly performed by humans. One such technological innovation is the embedded system-based sensor array module such as flex sensor, temperature sensor, and pH sensor that have been used to monitor the turmeric finger growth characteristics. The experimental work has been tested with five different nodes and the average flex sensor resistance changes in five nodes are calculated. Among the five nodes, nodes II and V were diseased. Purposely node II was left as such and node V was treated with Pseudomonas and viride to restrict the Rhizome rot disease attack. As a result, after cultivation, it was found that the Rhizome rot disease attack on node V is comparatively lesser than node II. The greatest advantage of this method is that it helps the farmers to detect the Rhizome rot disease and also prevent it an early stage by monitoring the growth of the turmeric fingers when it is under the soil.
