Sclerotium population of Sclerotinia sclerotiorum were variable duringthis 3-yr study; however, sclerotia did not accumulate in increasing numbers in fields planted to susceptible dry edible bean (Phaseolus vulgaris) cultivars despite annual white mold epidemics. Populations ranged between one and three sclerotia/kg air-dried soil in bean fields. A3-yr crop rotation did not reduce sclerotium population significantly.A low sclerotium population of 0.2kg soil produced sufficient inoculum(ascopores) to infect 46% of the plant canopy during 1975. Sclerotia were redistributed within a field by irrigation water. During august, numerous sclerotia germinated to form 11-14 and 7-11 apothecia/m2 in bean and sugar beet fields, respectively. An average of two apothecia were produced by each germinated sclerotium in both crops... |
