Other claims from this paper (17)
- Intervention effect Adding potassium to the fertilizer reduced fruit grey mould incidence caused by Botrytis cinerea in cucumbers by 27–33% when nitrate was low.
- Intervention effect Adding calcium generally reduced grey mould in cucumbers by 35–50%.
- Intervention effect The fungicide diethofencarb reduced grey mould in cucumbers by 39%.
- Intervention effect The fungicide carbendazim reduced grey mould in cucumbers by 50%.
- Intervention effect In the second year potassium treatment decreased stem infection with B. cinerea by 50%.
- Intervention effect In the second year fungicide treatment decreased stem infection with B. cinerea by 50%.
- Intervention effect In the second year calcium treatment decreased stem infection with B. cinerea by 60%.
- Intervention effect Only the calcium treatment was significantly different from the basic fertilizer control.
- Intervention effect Calcium treatments were effective on cucumber crops only under high relative humidity, at two out of four sampling dates.
- Association The effect of calcium in cucumber could not be separated from the high nitrate level associated with its use.
- Intervention effect Potassium enrichment reduced natural incidence of downy mildew caused by Pseudoperonospora cubensis.
- Intervention effect Neither potassium nor calcium reduced incidence of powdery mildew in cucumber crops.
- Intervention effect Adding calcium to the fertilizer reduced disease in an eggplant crop.
- Intervention effect Adding calcium to the fertilizer increased yield of an eggplant crop.
- Intervention effect Adding calcium reduced grey mould of pepper by 50–60%.
- Intervention effect A single application of calcium sulphate alone or with calcium dihydrogen phosphate reduced grey mould in artificially inoculated pepper in glasshouse.
- Intervention effect A single application of calcium sulphate alone or with calcium dihydrogen phosphate reduced grey mould in artificially inoculated eggplant in glasshouse.
