Abstract

Abstract:

“Jinzhu” cherry tomato was used to investigate the effect of preharvest fungicide spraying on the incidence
of diseases, weight loss, eating quality and SYP-Z048 residues of postharvest fruits. The results showed that pre-harvest
fungicide spraying dramatically reduced the disease incidence of postharvest “Jinzhu” cherry tomato, increased the contents
of vitamin C and total soluble solids (TSS) and delayed their loss during postharvest storage, but did not significantly
affect weight loss and the content of TA (P < 0.05). The best pre-harvest fungicide was SYP-Z048 at a concentration of 0.4 g/L.
SYP-Z048 residues revealed a declining trend both in preharvest cherry tomato fruits and in postharvest ones, declining
slower in postharvest fruits. Moreover, lower storage temperature resulted in a slower declining rate.

Key words: preharvest fungicide spraying, cherry tomato, quality, SYP-Z048 residues
