Conteúdo: | Every population of soybean seeds has the potential of carrying a wide variety of microorganisms, including fungi and bacteria, many of which can cause disease in soybean plants. Under certain conditions, fungi and bacteria kill the seed before it can germinate or emerge from the soil. The potential effects of fungi and bacteria on soybean seeds are illustrated by studies of Bacillus subtilis Phomopsis spp. (Diaporthe phaseolorum var. sojae). Seed-borne microorganisms reduce market quality of the crop besides carrying pathogens into the field the following season. Foliar fungicide sprays and seed dressings are important means of controlling seed-borne microorganisms in soybean. Foliar sprays can reduce the amount of Phomopsis spp. that enters the seeds near the ebd of the growing season and after maturity, but does not guarantee that all seeds will be free of microorganisms. If a seed lot has a high percent of infected seeds, seed dressing with a fungicide or antibiotic or both will help control the growth of these microorganisms, allowing many of the seeds to germinate and emerge. A method for treating soybean seeds using solvents such as dichloromethane and polyethylene glycol is described. When K penicillin G was combined with thiram the full germination potential of the seed lot was realized in the field.
