Table 5 Damage reduction rate of shoot and root dry weight (%) and disease severity index values recorded by melon seedlings inoculated with two F. oxysporum f. sp. melonis isolates and treated preventively by four Aspergillus spp. isolates, two Penicillium spp. isolates, and two Trichoderma spp. in vivo assay

From: Evaluation of the efficiency of Trichoderma, Penicillium, and Aspergillus species as biological control agents against four soil-borne fungi of melon and watermelon

  1. aDamage reduction rate values present the mean of three replicates (5 plants/replicate); R (%) = ((DWA − DWP) / DWA) × 100, where DWA is the dry weight (shoot and root) of inoculated plants with antagonist and DWP is the dry weight (shoot and root) of inoculated plant with only the pathogen and disease severity index scale (Table 3), which present the mean of three replicates (5 plants/replicate)
  2. bDuncan’s multiple range test: values followed by different letters are significantly different at P ≤ 0.05
