In the EC at the moment only cupper and sulphur products are allowed to regulate a multiplicity of diseases
in different vegetable crops. On the other hand it is well know that both have also negative side effects on
beneficial organisms and the soil. Since many years researches are looking for alternatives to reduce and
substitute the use of the mentioned products.
Bicarbonates are substances which were pointes out for many years. They are present in nature and were
used in the past in organic farming. Until now there was no registration for them in the EC as plant protection
materials. There is a palpable possibility that it would change in future, what will open the possibility to apply
for the introduction of potassium bicarbonate in annex 2B of the EC Reg. 2091/92. In South Tyrol in the last
years were carried out field trials which showed an interesting efficacy against scab. Frequent use of potassium
bicarbonate increased the mineral content of potassium in the fruits and increased the number of fruits
with bitter bit during storage.
