Abstract:
Pea is third most important pulses crop at global level, after dry bean and chick pea and third most important Rabi pulse of India after chick pea and lentil. Present investigation was done to evaluate the efficacy of different fungal and bacterial bio-agents viz., Trichoderma hamatum Trichoderma viride, Chaetomium spp. Bacillus subtilis and Pseudomonas fluorescens against Sclerotinia sclerotiorum (Lib.) de Bary cause sclerotinia stem rot of pea (Pisum sativum L.). Indiscriminately use of chemical fungicides for protection of crops from diseases is not merely injurious to human health but also unsafe for our environment. The results were obtained from the present investigation showed that the minimum mycelial growth and maximum mycelial inhibition growth of tested fungus were observed in Trichoderma viride followed by Trichoderma harzianum and Chaetomium sp., while maximum mycelial growth and minimum inhibition zone was observed in case of Bacillus subtilis as compared to control. Therefore we say that on basis of present investigation the more study are needed for field application of these Bio-agents to manage the disease incidence and severity of sclerotinia stem rot of pea.
