✦ Synopsis

A model of aerial spore transport by Legg and Powell (1979) is modified here to account for passive liberation of spores by wind and its effect on the subsequent transport and deposition of spores within the crop. Spores blown from surfaces by wind are removed mainly during gusts when the wind speed exceeds a threshhold value characteristic of the particular fungus. The integration of this threshold into a transport model is described here. This new model adequately describes the decrease in concentration of Erysiphe graminis spores observed downwind of a source of infection within a barley crop.
