Abstract
Evaluation of different fungicides revealed that Maxim was the most effective as it prevented the in vitro growth of F. solani, M. phase-Ono, athoobromae, S. rollsii and R. solani, at 1-5 ppm, followed by Benlate at (10-800 ppm). Vitavax-T (25.200 ppm) and Rizolex-T (200800 ppm). Apron and Monceren had no or little effect and failed to produce a considerable reduction in growth of all tested fungi even at 800 ppm. Among the tested plant products, thyme extract was the most effective in vitro against all tested fungal pathogens. followed by Trilogy (neem oil) and Kenze oil (castor oil). Reduction in fungal linear growth was increased more or less by increasing the concentration of these plant products; however, Leek extract had no effect in this respect. As for antagonistic microbes, both Rizo N and Plantguard caused significant decrease in linear growth of the tested fungi. Rizo N was significantly better than Plantguard; however, both antagonistic microbes, may be considered weak in terms of their toxicity against the tested pathogens.
