Abstract

Inhibition of conidial germination of Bipolaris sorokiniana was tested using eight ethanolic plant extracts, ten aqueous plant extracts in combination with cow dung and five aqueous plant extracts in combination with cow urine. Hundred percent of conidial germination was inhibited with the application of ethanolic extracts of Adhatoda vasica (leaf) and Zingiber officinale (rhizome) at 2.5% concentration. After the treatment with Vinca rosea, Piper betle and Azadirachta indica extracts in combination with cow dung suspension showed 100% inhibition of conidial germination; where the lowest was noted in case of Rauwolfea serpentina (30%) extract at same concentration. At 2.5% concentration of Calotropis procera extracts in combination with cow urine, 91% inhibition of conidial germination was observed. In most cases, Ocimum sanctum extract exhibited less inhibitory effect against B. sorokiniana. Key words: Bipolaris sorokiniana, Leaf blight, Plant extracts, Triticum aestivum, Cow dung, Cow urine.
