Although not required for infection, wounding has been reputed to enhance anthracnose (caused by the fungus Colletotrichum cereale Manns) of annual bluegrass [ABG; Poa annua L. f. reptans (Hausskn) T. Koyama] turf.  Research on the effect of wounding on anthracnose severity of ABG is limited.  In particular, any influence of mechanical injury from scarification (vertical cutting) on disease severity remains unclear.  A field study was initiated in North Brunswick, NJ on ABG turf (mowed at a 2.8-mm height) to evaluate the effect of scarification depth (1.3- and 7.6-mm) on anthracnose severity.  The trial used a CRD with ten replications and plot size of 0.5- by 1.5-m.  Treatments were applied with a scarifying reel having 1.5-mm wide blades with a 40-mm lateral spacing.  After treatments were applied (23 July 2010 and 6 July 2011), transects were established directly over the scarification lines of treated plots and randomly positioned over turf in non-scarified plots.  Disease observations were made at 10 positions along each of three 25-cm transects within each plot (30 observations per plot).  All transect-observations were performed at the same 30 locations within each plot.  Disease severity was evaluated immediately after scarification and every 1- to 5-d through Aug. 2010 and 2011.  Disease severity was 5% at the initiation of the trial in both 2010 and 2011.  Over 10 observation dates in 2010, there was one difference between treatments; deep scarification (7.6 mm-depth) had slightly (3%) greater disease severity than the control 7-d after scarification was applied.  As of mid-July 2011, no differences were observed between treatments.  The trial will be repeated for a third time during late summer 2011.  To date, findings do not support the hypothesis that mechanical injury from scarification increases anthracnose severity.
