Abstract:

          A highly significant evidence of the fungicidal action of furfural on wheat flag smut (Urocystis agropyri Preuss) Schrot was observed. Soaking inoculated wheat kernels in furfural (1000-10000 ppm), caused significant reduction in disease incidence. The incidence was reduced from 85.3% to 13% when the inoculated kernels were soaked in 10000 ppm furfural for 5 minutes. However, similar results were also obtained when the inoculated seeds were thoroughly mixed with charcoal impregnated with furfural (5000-10000). The efficiency of furfural was demonstrated under favorable conditions for flag smut disease development.
