Effect of some micronutrients and the antioxidant salicylic acid on suppressing the infection wiffi strawberry powdery mildew disease [electronic resource].

Includes reference.

Spraying strawberry plants with three micronutrients, i.e., ferrous ( Fe ) , manganese ( Mn ) and zinc ( Zn ) , singly or in different combinations, and in combination with the inducing systemic acquired resistance (ISAR) salicylic acid significantly reduced the severity of infection with powdery mildew disease , caused by Sphaerotheca macularis ,and increased fruit yield compared with the control. In addition, spraying ISAR salicylic acid alone was more effective in reducing the disease than spraying micronutrients alone. Furthennore, spraying the plants with ISAR salicylic acid three times in combination with at least two of the tested micronutrients was a more effective treatment in this regard, where no apparent symptoms of the disease were observed and also resulted in the highest fruit yield, total soluble solids (T.S.S.) and fruit firmness.
