Influence of preharvest application of fungicides on the postharvest quality of tomato (Solanum lycopersicum L.)

a b s t r a c tChemical fungicides are widely used for the control of preharvest fungal diseases. However, they may induce changes in quality characteristics, accelerating or delaying senescence. The effects of preharvest application of fenhexamid, or pyraclostrobin + boscalid, on tomato fruit (Solanum lycopersicum L.) cvs. Raf, Amadeo and Nereida, were compared to untreated fruit at harvest and during storage. The impact of fungicides in Nereida tomatoes was notable as fruit treated with fenhexamid displayed increased in maturity index, weight loss and the accumulation of vitamin C compared with fruit treated with pyraclostrobin + boscalid. Preharvest application of pyraclostrobin + boscalid delayed ripening and senescence of long life Nereida tomatoes and therefore affected postharvest…
