Antibiotic activity was detected in soybean (Glycine max ‘Wells’) seeds after soaking them for 0.5, 1.5, 4, or 24 hours in various concentrations of potassium penicillin G (PG) in dichloromethane (methylene chloride). Zones of inhibition around treated seeds increased in size with increase in soaking time and increase in concentration of PG. Germination and seedling vigor, immediately after treatment, was not adversely affected.
