Treatment of bean (Phaseolus vulgaris) seeds with tolelofos‐methyl reduced pre‐emergence mortality and hypocotyl rot caused by Rhizoctonia solani. The fungicide was effective when applied either as a dust treatment or by infusion in acetone solution. Neither the acetone infusion nor the dust application had any adverse effects on the germination of seeds sown in uninfested soil. Acetone infusion was effective after short periods of immersion (1 min) and with repeated use of the same solution, thus resulting in more efficient use of the fungicide. Both methods of fungicide application effectively controlled rhizoctonia diseases in the field.
