In this study, the effect of organic fertilizer (EBG Care), biofertilizer (Ecoset), biological fungicide (Subtilex foliar) and chemical fungicide (Sanga WG) treatments on the antioxidant compounds, quality parameters and postharvest life of strawberry fruit (Fragaria × ananassa Duch cv. ‘Festival’) were investigated. The strawberry plants were sprayed with these products during flowering stage 22 days before harvest. All fruit were harvested at red maturity stage and stored for 20 days at 0 °C temperature and 90–95% relative humidity. The organic fertilizer treatment showed the highest L*, C*, h° values, total flavonoid, anthocyanin, oxalic acid contents and antioxidant activity. Biofertilizer determined maximum ferulic acid while biological fungicide had the highest total soluble solids content compared to the chemical fungicide and control treatments. The chemical fungicide treatment exhibited the highest amount of citric acid with control showing maximum total phenolic, malic acid, gallic acid and quercetin content. The findings obtained in this experiment concluded that pre-harvest application of organic fertilizer successfully maintained the maximal fruit quality and postharvest life of Festival cv. of strawberry for 20 days of cold storage among the treatments applied.

本研究探讨有机肥（EBG Care）、生物肥（Ecoset）、生物杀菌剂（Subtilex foliar）和化学杀菌剂（Sanga WG）处理对草莓果实（Fragaria  ×  ananassa ）抗氧化成分、品质参数和采后寿命的影响。 Duch cv.'Festival'）进行了调查。在收获前 22 天的开花期用这些产品喷洒草莓植物。所有果实在红色成熟期收获，并在 0°C 温度和 90-95% 相对湿度下储存 20 天。有机肥处理L *、C *、h最高°值、总黄酮、花青素、草酸含量和抗氧化活性。与化学杀菌剂和对照处理相比，生物肥料确定了最大阿魏酸，而生物杀菌剂具有最高的总可溶性固体含量。化学杀菌剂处理显示出最高量的柠檬酸，对照显示最大总酚、苹果酸、没食子酸和槲皮素含量。本实验获得的结果表明，收获前施用有机肥成功地保持了Festival cv.的最大果实品质和收获后寿命。在应用的处理中，草莓冷藏 20 天。
