Wheat yellow rust is one of the most important diseases with substantial crop losses in cool and humid regions. An alternative and less expensive chemotherapy would be used as systematic fungicides were applied as a seed treatment. Studies were conducted in the greenhouse and field to determine potential of systemic seed treatments for control of yellow rust of wheat and to determine the effects of the treatments of plant growth. The following fungicides applied as slurries to seed of Bolani wheat (Susceptable): Tebuconazole (Raxil 2 W. P), Triadimefon (Bayleton 25 W.P), Triadimenol (Baytan 7.5 W.P), Diniconazole (Sumi- 81 W. P), Propiconazole (Tilt 25 EC), Flutriafole + Thiabendazole (Vinsit 5 W.P). Fungicides were applied at 0.25, 0.5, 1, 1.5, 2, 2.5 g.a.i./Kg of seed, respectively. The treated seeds were sown in two rows with 2m longh. Eight plants of each plot were transplanted in pots and then inoculated with urediospores high virulence race (134 E150) in seedling and Boot stages
