Evaluation of the users value of salts against apple scab and powdery mildew for fruit production

Abstract: The research was aimed at finding anti resistance strategies for Integrated fruit growing. \nAs the salts tested may be approvable for organic farming, the trial results are also of \nvalue for the development of scab an mildew control strategies for organic fruit growing. As \nnew fungicides are mainly unisite action fungicides, the problem of fungicide resistance \ndevelopment is becoming more important every year. Combining chemical fungicides, \nwhich is the best anti-resistance strategy, is not always possible or recommended in the \ncase when the number of available chemical fungicides are limited or a reduction in \nfungicide use is asked for. Therefore the use of salts as an anti-resistance strategy was \nlooked upon. The salts evaluated were K(HCO3), KH2PO3, KHPO4 and K2SiO3. When \nusing these salts as an anti-resistance strategy the efficacy obtained when spraying the \ncompounds alone was often to low to be used in rotation with chemical fungicides. Only \nwith K(HCO3)2 a good efficacy can be observed in some years. The variation in efficacy \nwith K(HCO3)2 observed is higher for powdery mildew. K(HCO3)2 can be considered as a \nideal product for scab control in organic orchards at moments of low infection risk.
