Fungitoxicity of mineral oils against Rhizoctonia solani causing damping‐off of mung bean (Phaseolus aureus)

Abstract

S U M M A R YThree mineral oils, BSO, EWOS and E9267 and one vegetable oil (mustard oil), did not appreciably inhibit the mycelial growth of Rhizoctonia solani. However, treatment of IOO g seeds of mung bean with z ml EWOS and E9267 oils controlled more than 90% of the pre-and post-emergence damping-off and protected seedlings in soil inoculated with R. solani 5 days after sowing. Soaking seeds in solutions of these oils or drenching the soil did not control damping-off.Mustard oil controlled only pre-emergence damping-off.
