Abstract:

In chilli (Capsicum annuum L.) several diseases are caused from fungal, bacterial and viral origin. Among the fungal diseases, damping off caused by species of Pythium is very common in the nursery which causes about 90 per cent mortality in nurseries and fields. Present experiment was carried out in in-vitro and in-situ conditions at Department of Plant Pathology, SHUATS in Completely Randomized Design with eight treatments and three replications each. The dominant pathogen, which causes damping-off of chilli, was isolated and identified as Pythium aphanidermatum. Bio-control agents Trichoderma harzianum and Pseudomonas fluorescens were isolated from different crops of healthy rhizosphere soils in different geographical regions. The in-vitro studies revealed that Lanatana camara (20 ml) carbendazim fungicide (8ppm) showed the highest mycelial growth inhibition (100 %) over the control and both antagonists were compatible with each other. Under nursery conditions, maximum germination percentage was recorded in carbendazim seed treatment (80 %), Lantana camara (100 ml/kg) soil treatment (76.00 %), [Trichoderma harzianum+ Pseudomonas fluorescens] +Lantana camara [seed] + soil treatment (70.66 %), Trichoderma harzianum + Pseudomonas fluorescens seed treatment (68.00 %), Trichoderma harzianum seed treatment (64.00%), Pseudomonas fluorescens seed treatment (60.00 %) when compared to the T0 - relative control (treated control) (13.33 %) and T1 - absolute control (untreated control) (78.66 %).Maximum root length was recorded in treatment carbendazim (4.29 cm) followed by T5 - Trichoderma harzianum+ Pseudomonas fluorescens (3.80 cm). Maximum shoot length was recorded in treatment T7 – carbendazim (4.52 cm) followed by T5 - Trichoderma harzianum+ Pseudomonas fluorescens (4.1 cm).
