| Abstract | ||||
| Seven diazoaminobenzene derivatives:1,3-Diphenyltriazene (diazoaminobenzene), 1,3-Bis(2-tolyl)-1-triazene, 1,3- Bis (4-tolyl)-1-triazene, 1,3- Bis (4-phenylcarboxylic acid)-1-triazene, 1,3- Bis (4-phenylsulphonamide)-1-triazene, 1,3- Bis (3-chlorophenyl)-1-triazene and 1,3-Dinaphtyl-1-triazene were prepared, purified and spectroscopically identified with IR, UV, NMR and Ms spectroscopy measurements. These derivatives were tested for their fungicidal and bactericidal effects against phytoparasitic microorganisms. It was found that Substitution with 2-CH3 significantly increased the effect of 1,3-diphenyl-1-triazezene against A. solani, while 4-CH3, 3-Cl and 4-COOH reduced it. Substitution of 1, 3-dinaphthyl- instead of 1,3-diphenyl- increased the activity against B. cinerea, R. solani and S. rolfsii on contrary to F. oxysporum. 1,3-Diphenyl-, 1,3-dinaphthyl- and 1,3-bis(2-tolyl)-1-triazene were more effective on E. carotovora than A. tumefaciens. | ||||
