Abstract
A study was conducted to evaluate efficiency of Mycotal at a concentration of 1.2 × 107 spores/ml and the fungus Trichoderma harzianum at concentrations of 1.5 × 106 and 1.5 × 107 spores/ml on nymphs and adults of the whitefly, Bemisia tabaci under field conditions on the eggplant, Solanum melongena. The results revealed that Mycotal active substance is the fungus Lecanicillium muscarium, showed the highest average relative efficiency in killing nymphs and adults in the Mycotal treatment, which amounted to 79.93 and 85.62%, respectively, compared with T. harzianum treatment for the two concentrations, which amounted to 60.76 and 67.76% for nymphs and 69.55 and 72.19% for adults, respectively under field conditions. The results also showed that the Mycotal achieved the best relative efficiency in killing whitefly adults, which amounted to 78.5, 86.07, and 92.3% after 3, 5, and 7 days, respectively, with a significant difference compared to the concentrations of the fungus T. harzianum, which were 52.35, 75.60, and 80.70% at a concentration of 1.5× 106 spores/ml and 55.10, 78.37 and 83.08% at concentration of 1.5 x 107 spores/ml after 3, 5 and 7 days of treatment, respectively.
