Summary:The deposition of conidia of B. cinerea on spore traps with different trapping orientations was studied in glasshouses. Three spore trap types with different angles to the horizontal were used, a horizontal trapping surface, a similar one at an angle of 45 °, and two vertical trapping surfaces exposed in opposite directions. The highest spore catches were obtained with the horizontal and slanted spore traps. In general, the horizontal spore trap was the most efficient. These results indicate that sedimentation without significant effects from air turbulence is a major factor for the depostion of B. cinerea spores in glasshouses.
