Abstract:

The activity of defense enzymes viz., peroxidase, polyphenol oxidase, catalase and superoxide dismutase up on treatment with azoxystrobin and chaetoglobosin was studied in this experiment. The chilli plants inoculated with C.capsici showed various levels of peroxidase activity with respect to the treatments. The combined application of azoxystrobin with chaetoglobosin at 0.2 per cent concentration showed the highest level of peroxidase activity (1.130). The next highest level (0.872) was observed in azoxystrobin with tebuconazole combination. In the case of chilli plants inoculated with L. taurica, the maximum peroxidase activity was recorded in the same combination (0.817). The highest polyphenol oxidase activity in chilli plants inoculated with C.capsici recorded in azoxystrobin and chaetoglobosin combination (0.883). The next best increase (0.721) of PPO was noted in combined application of azoxystrobin with tebuconazole at 0.2 per cent concentration. The same trend was noticed when chilli plant inoculated with L. taurica. In the case of catalase and superoxide dismutase, azoxystrobin and chaetoglobosin combination, followed by azoxystrobin (Willowood) and tebuconazole combination showed the highest level of activity in chilli plants inoculated with C. capsici and L.taurica.
