Abstract:
The purpose of this study was to evaluate the efficacy of fungicides and bio-control agents In vitro against Alternaria alternata, which causes tomato early blight. Using the poison food technique, six fungicides were evaluated: four systemic (Propiconazole, Azoxystrobin, Hexaconazole, and Copper oxychloride) and two non-systemic (Mancozeb and Chlorothalonil) at five concentrations (25, 50, 75, 100, and 150 ppm). The dual culture technique was used to test three bio-control agents: Trichoderma viride, Trichoderma harzianum, and pseudomonas fluorescence. Propiconazole, a systemic fungicide, was shown to be extremely effective, with 100 percent inhibition at all dosages. Trichoderma viride (71.71 percent) inhibited the radial growth of the test fungus the most, followed by Trichoderma harzianum (67.00 percent) and pseudomonas fluorescence (67.00 percent) (54.00 percent) In this investigation, however, pseudomonas fluorescence (54.00 percent) was the least effective.
