| 中文摘要 | 背景：聯合國糧農組織報告指出，約40%的糧食損失是由植物害蟲和疾病（包括真菌感染）造成的。持續使用農用化學品來控制真菌感染導致了殺菌劑抗藥性的出現。炭疽病菌（Colletotrichum spp.）是草莓炭疽病的主要病原體，因其抗殺菌劑問題而受到關注。 方法：本研究中，我們通過整合多分枝花狀氧化鋅（fZnO）和農藥三氟羥基嘧啶開發了新型的抗真菌策略。fZnO化合物使用環保且高效的水熱法合成。帶有立體結構的帶電聚合物，如親水性的聚丙烯酸（PAA）和聚乙烯亞胺（PEI），被接枝到fZnO表面，以提高化合物的懸浮能力。我們將接枝的fZnO化合物與殺菌劑三氟羥基嘧啶結合使用，並評估其體外和體內的活性。 重要發現：接枝的fZnO（80 ppm）和三氟羥基嘧啶（100 ppm）有效抑制了抗殺菌劑的Colletotrichum spp.的生長，並限制了草莓葉片上的炭疽病。PEI接枝的fZnO因其光催化活性和抵抗環境因素的能力，顯示出作為可持續農業中環保添加劑的潛力。 |
| 英文摘要 | Background: The Food and Agriculture Organization has reported approximately 40 % of food loss due to damage from plant pests and diseases, including fungal infections. Continuous application of agrichemicals for controlling fungal infection cause the occurrence of fungicide resistance. Colletotrichum spp., major causal agents for strawberry anthracnose, have gained concern for fungicide resistance issues. Methods: We developed novel antifungal strategies in the present study by integrating multibranched flower-like ZnO (fZnO) and agrochemicals (trifloxystrobin). fZnO compounds were synthesised using an eco-friendly and efficient hydrothermal method. Charged polymers with steric structures, such as hydrophilic polyacrylic acid (PAA) and polyethyleneimine (PEI), were grafted onto fZnO surfaces to improve the suspension ability of the compounds. We used the grafted fZnO compounds in combination with the fungicide trifloxystrobin to evaluate the in vitro and in vivo activities. Significant findings: Grafted fZnO (80 ppm) and trifloxystrobin (100 ppm) effectively inhibited the growth of fungicide-resistant Colletotrichum spp. and limited strawberry anthracnose on leaves. PEI-grafted fZnO shows promise as an eco-friendly additive in sustainable agriculture due to its photocatalytic activity and ability to withstand environmental factors. |
| 發表成果與本中心研究主題相關性 | 本研究的發表成果與農業中心的研究主題密切相關，因為它探討了抗真菌策略在農業中的應用，特別是針對草莓炭疽病的防治。透過整合接枝氧化鋅（fZnO）與農藥三氟羥基嘧啶，該研究提供了有效抑制抗殺菌劑病原體的解決方案，減少農作物損失。此研究不僅有助於改善作物健康，還促進了可持續農業發展，因為使用的環保材料顯示出降低農藥依賴性的潛力，符合現代農業對於環保和可持續性的需求。 |
