FIG 6.

Cumulative numbers of Fusarium graminearum ascospores trapped over time (DOY) (A) and at the end of the trapping period (B) above maize stalks in outdoor experiments in 2011 (□) and 2012 (○) as affected by exposure conditions. Maize stalks were arranged on a grass lawn (white) or on a wet florist foam (black) as described in the legend to Fig. 5, and spore traps (microscope slides with adhesive tape facing down) were placed 3 to 5 cm above the stalk pieces. Points in panel A and bars in panel C are averages of 10 values: two stalk types (artificially inoculated and naturally infested by F. graminearum) and 5 replicates per stalk type. Whiskers in panel B are standard errors of the 10 values.
