Abstract
Seven diazoaminobenzene derivatives were prepared, and tested for their phytocidal activities against wheat (T. aestivum) and squash (Cucumber pepo) seeds germination, seedling growth and dry weigh of the grown seedlings. Their molluscicidal effect on the terrestrial snail, Theba pisana was also studied. The tested triazene derivatives inhibited the seed germination, the produced seedlings growth and the dry weight increasingly with increasing the concentration and differently based on the derivative structure. Substitution with 2-CH3 increased the germination inhibition with non-significant differences on shoot and root systems growth compared with 1,3- diphenyl-1-triazene. Vice Versa, 4-CH3 substituent decreased the effect. The structure activity relationship of the tested compounds against the seed germination, the produced seedlings growth and the dry weight was illustrated. Regarding the molluscicidal effect, 1,3-Bis(2-tolyl)-1-triazene caused moderate lethal effect, while the other derivatives required to use higher concentrations than 10% to be significantly active against the treated snail.
