Evaluation of Different Fungicides and Biopesticides Against Stem Rot of Rajmash (Phaseolus vulgaris L.)

Stem rot caused by Sclerotinia sclerotiorum is an important disease of Rajmash (Phaseolus vulgaris L.) in Eastern U.P. The efficacy of seven fungicides and two bio-pesticides were tested in-vitro and in vivo. Vitavax (0.10 %), Bavistin (0.10%) and Blitox-50 (0.20%) proved to be most effective in inhibiting the growth of the pathogen and controlling the disease in the field and increasing the yield also. Bio-pesticides, Neemark and Funginil are also proved effective, but slightly less effective than systemic fungicides. Neemark and Funginil being a safe eco-friendly and economical bioproduct, can be used in the control of the diseases.
