Abstract

Effect of plants leaf extracts, i.e. Garlic, Oak, Neem, Dathura, Partheneium, Tulsi, Castor and Ashwagandha were studied at four different concentrations (3, 5, 10 and 15 %). Barley stripe rust disease was tested on susceptible barley cultivar RD 2035 under artificial rust inoculation conditions during two consecutive Rabi, seasons 2016-17 and 2017-18 in cage house. All concentration of eight plants leaf extracts increased per cent disease suppression and decrease the per cent disease severity, than in the control. Among these extracts garlic clove extract proved as best with highest per cent disease suppression (53.10) and significantly low mean per cent rust severity (39.78) followed by leaf extracts of neem (Azadirachta indica), tulshi (Ocimum tenuiflorum), datura (Datura stramonium), oak (Calotropics gigantean), partheneium (Parthenium hysterophorus), castor (Ricinus communis) and ashwagandha (Withania somnifera).
