Effects of Temperature and Wetness Duration on the Sporulation of <i>Phomopsis viticola</i> on Infected Grape Canes

Fig. 3. Predicted and observed spore density in a ‘Catawba’ grapevine vineyard in 2009 (A) and 2010 (B). Bars represent mean α-conidia per trap per sporulation event. Dates correspond to rain event ending dates. The plotted line represents sporulation/mm² infected cane tissue predicted by the model developed under Objective 1. Plot of observed and predicted spore density in spore traps for the ‘Catawba’ vineyard in 2009 and 2010 (C).
