Antifungal efficacy of Zanthoxylum oil against <i>Bipolaris sorokiniana</i> (Sacc.) Shoem.

Abstract

Bipolaris sorokiniana (Sacc.) Shoem. is the most economically important foliar blight pathogen of wheat in all warm zones. Essential oil of Zanthoxylum armatum D.C. was used to determine its efficacy against Bipolaris sorokiniana by calculating the percentage of mycelial growth inhibition. The oil showed 25, 37.8, 42.8, 75, 84.5 and 100 percent inhibition of mycelial growth at 5.0, 10.0, 15.0, 20.0, 30.0 and 40.0 μl ml^-1 ppm concentrations of essential oil against the test fungus, respectively.
