^aHealthy seedling stands were determined 7 days after sowing.

^bInoculated by placing a disk containing P. ultimum sporangia adjacent to the seed (see Materials and Methods).

^cCoated onto the seed at the rate of 5.6 × 10⁶ cells/seed.

^dEfficacy = [1 − (nontrt/noninoc − trt/inoc)/(nontrt/noninoc − nontrt/inoc)] × 100, Numbers in each column followed by the same letter are not significantly different (P = 0.05) according to Tukey's method for pairwise comparisons. where nontrt/noninoc is the number of sporangia that were not treated with Pythium and not inoculated with E. cloacae that germinated, trt/inoc is the number of sporangia that were treated with E. cloacae and inoculated with P. ultimum that germinated, and nontrt/inoc is the number of sporangia that were not treated with E. cloacae but were inoculated with P. ultimum that germinated.
