Two experiments on 10 years old mango trees, Saddeka cv. (high susceptible cultivar) were conducted under field condition during 2012 and 2013 growing seasons for management of powdery mildew at El Adleia district, Belbees county, El-Sharkia governorate. In these trials, mango trees were sprayed with two potassium phosphate salts , calcium chloride ,three commercial growth regulators ,i.e. Agrotone (NAA), Cultar (paclobutrazol) , and Berelex (GA3), the bio-fungicide AQ10 (Ampelomyces quisqualis) , the commercial systemic fungicide Punch (flusilazole) and an alternate among Cultar ( paclobutrazol ), monobasic phosphate and the fungicide Punch. The aforementioned treatments were applied at 14 days intervals during both growing seasons starting at bud flower burst stage till full bloom stage in order to evaluate their efficiency on management mango powdery mildew disease. The obtained results showed that spraying of mango trees ( Saddeka cv.) during 2012 and 2013 growing seasons with any of the tested treatments significantly reduced the severity of powdery mildew with significant increase to the produced fruit yield compared with control treatment.In addition, results of both seasons revealed that alternation spray among Cultar ( paclobutrazol ), mono basic potassium phosphate and the fungicide Punch was the most superior treatment in reducing severity of the disease and producing the highest fruit yield followed by spraying of the fungicide Punch then spraying of mono basic potassium phosphate . Meanwhile, Brelex was of the lowest efficiency treatment in this regard followed by spraying of Agrotone . The other treatments recorded intermediate figures. Control treatment recorded 44.3 % disease severity and produced poor fruit yield.
