Table 1 Mean percentage growth inhibition of the tested plant pathogenic fungi on potato dextrose agar (PDA) plates treated with CFC of Photorhabdus luminescens BSDS and P. luminescens MAP

From: Two Philippine Photorhabdus luminescens strains inhibit the in vitro growth of Lasiodiplodia theobromae, Fusarium oxysporum f. sp. lycopersici, and Colletotrichum spp.

  1. Separate analysis was done for each bioassay setup using the average of the two trials
  2. Means within the same column are being compared
  3. Means with the same letter are not significantly different at α = 0.05 using the LSD test
  4. Mean percentage fungal growth inhibition is computed using the following formula:
  5. [(Growth diameter in control plates − Growth diameter in treated plates)/Growth diameter in control plates] * 100
  6. CFC, cell-free culture filtrates; dpi, days post infection; TSB, tryptic soy broth
