| Abstract | ||
| The ability of some modern fungicides, biocides and organic acids to reduce verticillium wiltin Eggplant was carried out in this study. Eleven fungicide (active ingredient: Fludioxnil + Tebuconazole), Vincint (a.i.: Flutriafol) and Meta Z (a.i.: Metalaxyl + Thiram), Clean root (Bacillus subtilis) and salicylic acid were investigated by treating transplants of eggplant through dipping their roots in the recommended doses of these biocides. The disease incidence was significantly reduced in case of fungicides followed by clean root and salicylic acid in comparison with control treatment. The fungicides Vincint and Meta Z recorded the highest efficacy as 77% and 76.6%, respectively, hence both of them are systemic fungicides. They followed by the fungicide eleven which gave 70% efficacy. Meanwhile, salicylic acid was the least effective where it revealed 44% efficacy. Growth parameters and yield of eggplant measurements revealed high record with fungicides more than the other treatments. Concerning to peroxidase and polyphenoleoxidase activities in leaves of eggplant, it was observed that clean root and the fungicides Vincint, Meta Z and Eleven ones recorded high levels of activity for both enzymes. | ||
