Results and discussion

Any other information on results incl. tables

MIGRATED DATASET;
- 48 days after the last treatment, the fermentation was delayed from one to five days in comparison with the untreated samples, depending on the grape variety.
- After 48 days the concentration of phthalimide found in grape was of 0.38 mg/l in a single tested grape type. Because folpet descomposed to phthalimide in aqueous solution, on day 106, 1.36 mg/l of phthalimide and barely folpet were detected.
- The amount found was dependent on the time of harvest. However no correlation was possible between the amount of fungicide detected and the delay in fermentation, as many other factors are involved.
