Abstract

The effects of water stress, ammonium sulphate, sodium nitrate and ammonium nitrate on the incidence of blossom‐end rot (BER) in tomatoes was studied, using plants grown in peat modules. There was little evidence that water stress per se affected BER incidence, which was largely determined by the ammonium ion, as found in previous studies. Water stress increased ammonium and nitrate levels in both the peat modules and the leaves of the plants. This effect may account for the relation between moisture stress and BER reported by others.

The incidence of deaths due to botulism among water fowl in the Norfolk Broads, England, is closely related to two meteorological factors. These are the number of days in summer with a maximum air temperature of 21Β°C or more, and the excess of water evaporation over rainfall in the months April, May
