The present investigation was conducted at the experimental farm and laboratory of Etay El-Baroud Agriculture Research Station, Agricultural Research Center (ARC) during two growing seasons 2021 and 2022. The recommended and half recommended dosages of some foliar fungi-cides: Tilt® 25% EC , Nasrzol® 25% EC , and Montoro® 30% EC were examined on growth, yield and yield quality as well as grains viability of the commercial wheat cultivar Giza 171 compared with the control (untreated). The obtained results showed that, Wheat grains that treated with full dosage of Nasrzol® had the lowest water absorption ratios after 5 and 24 hr, while the highest grains germination was recorded in wheat plants that treated with 15 cm3/fed. of Nasrzol®. all the tested fungicides superior the control in increase tillers number/m2 and plant height during both seasons, except half recommended dosages of Tilt® and Nasrzol® in plant height. The highest numbers of spike/ m2, spike lengths, grain yield/ m2, straw yield/ m2 and biological yield/ m2 were recorded in the plants treated with the recommended dosage of Nasrzol® or full dosage of Tilt®. The highest carbohydrates percentage in the wheat grains and in straw was recorded in the plants treated with full dosage of Tilt® (25 cm3/fed.), followed by the plants that treated with full dosage of Nasrzol® during both seasons. While, the highest protein percentage in the wheat grains and in straw was noticed in the plants of control group, followed by the plants that treated with half dosage of Tilt®.
