Plants were rated for disease weekly, beginning three weeks after transplanting. An estimate of the percentage of foliage covered by lesions and foliage lost due to disease were combined into one defoliation rating (PERNEZNY et al. 1996). For the Spring 2001 trial, standard iterative procedures were used to calculate the area under the disease progress curve (AUDPC) (SHANER & FINNEY 1977). Plots were harvested 2 to 3 times at 10–14 day intervals beginning when about 10% of fruit began to turn pink. Final harvest dates were 30 May 2001, 27 December 2001, and 16 May 2002 for each of the experiments.At each harvest, all pink and red fruit within 3 m of row
in the center of each plot were counted, weighed, and sorted into several cull (defect) categories, including direct damage from target spot. All data were subjected to analysis of variance and Fisher’s Protected LSD mean separation procedure at P ≤ 0.05 (STEEL & TORRIE 1980).
