Abstract
Experiments were conducted to study the in vitro and in vivo efficacy of some new generation fungicides and antagonistic microbes against Ascochyta blight on chickpea at Experimental farm and laboratory of Lovely Professional University, Phagwara, Punjab during cropping season of 2017-18. Five different fungicides and two bio-control agents were tested against Ascochyta rabiei in laboratory and field conditions. In laboratory conditions, Trichoderma harzianum was recorded more effective than Pseudomonas fluorescens inhibiting up to 63.75 % growth of the pathogen. All the fungicides inhibit pathogen under in vitro condition but Propineb proved best by attaining lowest ED50 value of 8.28μg/ml while under in vivo conditions Azoxystrobin gave best results with lowest disease severity of 29.63 per cent among all the fungicides. In case of bio-agents, Trichoderma harzianum gave better results as compared to Pseudomonas fluorescens with disease severity 55.55% and 59.25% respectively.
