Abstract:
Parthenocarpic cucumbers were fertilized with N-P-K 7:3:7%. During two winter seasons when nitrate level in the fertilizer was low, addition of K to the fertilizer significantly reduced the incidence of fruit grey mould caused by Botrytis cinerea by 27-33%, whereas adding Ca generally reduced grey mould by 35-50%. The fungicide treatments, diethofencarb and carbendazim (at 0.25 g. L-) reduced grey mould by 39 and 50%, respectively. In the second year stem infection with B.cinerea was decreased by 50, 50, or 60% by treatment with K fungicide or Ca, respectively. Calcium treatments were effective on cucumber crops only under high relative humidity at two out of four sampling dates. The effect of Ca could not be separated from high nitrate level associated with its use in cucumber planting. Potassium enrichment reduced natural incidence of downy mildew Pseudoperonospora cubensis. Neither ion reduced incidence of powdery mildew Sphaerotheca fuliginea in cucumber crops. Disease reduction and increased yield of an eggplant crop were obtained by addition of Ca to the fertilizer. Grey mould of pepper was reduced by 50-60% by adding calcium, but pepper yield was not increased. A single application of calcium sulphate alone or with calcium dihydrogen phosphate to glasshouse plants resulted in a reduction of grey mould in pepper and eggplant inoculated with B.cinerea. -from Authors
