Chilli (Capsicum annuum) is one of the most important spice crop in the world having nutritive value especially rich in Vitamin C. It suffers excess yield loss by the infection of ischolar_main rot caused by Rhizoctonia solani worldwide. The present study was conducted to determine the effect of different inoculum levels of R. solani on growth and disease development of chilli cv. G-4 under pot conditions.The observations of this study revealed that R. solani is a potential pathogen, significantly reduced the length, fresh and dry weight of shoot and ischolar_main of chilli cv. G-4 and increase ischolar_main infection upto 5-65.7 per cent. The highest reduction in shoot length (27.5%), ischolar_main length (10.3%), shoot fresh weight (15.5%), ischolar_main fresh weight (4.3%), shoot dry weight (6.7%) and ischolar_main dry weight (1.3%) were observed at highest inoculum level of 4 g culture/kg soil. However, highest ischolar_main infection (65.7%) was observed at highest inoculum level i.e. 4g culture/kg soil,while ischolar_main infection was least (5.0 %) at lowest inoculum level i.e. 0.5 g culture/kg soil.

Abstract


Chilli (Capsicum annuum) is one of the most important spice crop in the world having nutritive value especially rich in Vitamin C. It suffers excess yield loss by the infection of ischolar_main rot caused by Rhizoctonia solani worldwide. The present study was conducted to determine the effect of different inoculum levels of R. solani on growth and disease development of chilli cv. G-4 under pot conditions.The observations of this study revealed that R. solani is a potential pathogen, significantly reduced the length, fresh and dry weight of shoot and ischolar_main of chilli cv. G-4 and increase ischolar_main infection upto 5-65.7 per cent. The highest reduction in shoot length (27.5%), ischolar_main length (10.3%), shoot fresh weight (15.5%), ischolar_main fresh weight (4.3%), shoot dry weight (6.7%) and ischolar_main dry weight (1.3%) were observed at highest inoculum level of 4 g culture/kg soil. However, highest ischolar_main infection (65.7%) was observed at highest inoculum level i.e. 4g culture/kg soil,while ischolar_main infection was least (5.0 %) at lowest inoculum level i.e. 0.5 g culture/kg soil.
