Calcium chloride, cupper sulfate and calcium carbonate led to more than 50% significant reduction in disease severity % and were more effective than ammonium phosphate and potassium dihydrogen phosphate. Golden Delicious and Royal Gala were found susceptible to the disease thus were subjected for post-infection treatment with some systemic fungicides or calcium chloride under field conditions. One week after the foliar spray, Triforine and Triadimenol were more effective than Carbendazim and calcium chloride in reducing the disease amount. Their reduction in disease progress was continued after one month from the day of the foliar spray. Calcium chloride was more effective at an application rate of 10 g L-1 than at 1 g L-1. Calcium chloride treatment did not give long-term efficacy especially in Royal Gala. Therefore, the use of salts as an anti-resistance strategy should be used in a rotation with chemical fungicides or combined with other control measures.]]>Abdel-Rahman, A.M.,1996Podosphaera leucotricha (Ell. and Ev.) salm.] on apples in the uplands of Jordan.]]>1996Anand, T., A.
