Conteúdo: | Sudden death syndrome, caused by straings of Fusarium solani, has beenrecognized as an important disease of soybean (Glycine max) in the southern United States for more than 20 years, but has only recently become more prevalent and severe in northern  soybean production areas. Little is known about environmental factors that influence root infection and above-ground symptom expression in this pathosystem. We established quantitative relationships between soil temperature, the matric component of soil water potential, and disease development in controlledconditions. Soil temperature in the range of 15 to 30 graus C was manipulated in pots equipped with heating tapes, and soil moisture was manipulated by withholding irrigation water until reached threshold...
