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

Egyptian Journal of Biological Pest Control

Table 6 Beneficial effect of four Aspergillus spp. isolates, two Penicillium spp. isolates, and two Trichoderma spp. isolates on melon plants in vivo assay, revealed by development rate of shoot and root dry weights (%)

Antagonists	Development rate of shoot dry weight %^a	Development rate of root dry weight %^a
A. flavus	11.45a^b	12.87a
A. fumigatus	8.03abc	10.16ab
A. niger	1.72d	4.55b
A. terreus	3.24cd	7.5ab
P. italicum	4.13bcd	7ab
P. digitatum	5.41bcd	6.14ab
T. viride	7.03abc	9.26ab
T. harzianum	8.36ab	10.08ab
P value	> 0.05	> 0.05

^aDevelopment rate presents the mean of three replicates (5 plants/replicate); D (%) = ((DWA − DW) / DW) × 100, where DWA is the dry weight (shoot and root) of the plants inoculated only by the antagonist and DW is the dry weight (shoot and root) of the healthy plants
^bDuncan’s multiple range test: means followed by different letters are significantly different at P ≤ 0.05
