| Abstract: | Greenhouse and laboratory experiments were conducted to determine the effects of various physical factors on the assessment
of disease caused by Sclerotium rolfsii using field and artificially infested soils. Lentil(Lens esculenta Moench) seedlings growing in trays or pots with sand were inoculated by surrounding them with a layer of soil infested with
the pathogen. The number of dead plants was maximal within a 10-day period following inoculation. Seedling mortality increased
with the number of sclerotia in the soil to a maximum that depended on seedling spacing, depth of the soil layer, and soil
type. |
