Abstract Apple trees cv. ‘Golden Delicious’ and ‘York’ were sprayed from bloom to fruit maturity with different products to evaluate the effect of pre-harvest treatments on fruit quality, including insect/disease damage and physicochemical fruit traits. Apple trees were assigned to five treatments: unsprayed (control), holistic solution (foliar nutrients and probiotics), insecticides, antimicrobials (fungicides and antibiotics), and a combination of antimicrobials + insecticides. The treatments started soon after bloom and were carried out every two weeks until fruit were ready to harvest. Diseases such as sooty blotch (complex of several fungi) and flyspeck (Zygophiala jamaicensis Mason) were the major source of damage on fruits. ‘Golden Delicious’ trees had a higher percentage of undamaged fruit than ‘York’, but all trees had some percentage of damaged fruit. Damage was most severe in the control (unsprayed) and insecticide treatments, intermediate in the holistic treatment, and much lower in the antimicrobial and antimicrobial + insecticide treatments (p

传统和替代的收获前处理影响“金冠”和“约克”苹果果实的质量

摘要苹果树 cv。'Golden Delicious' 和 'York' 用不同的产品从开花到果实成熟喷洒，以评估收获前处理对果实品质的影响，包括昆虫/病害和理化果实性状。苹果树被分配到五种处理方式：未喷洒（对照）、整体解决方案（叶面营养素和益生菌）、杀虫剂、抗菌剂（杀菌剂和抗生素）以及抗菌剂 + 杀虫剂的组合。处理在开花后不久开始，每两周进行一次，直到果实准备好收获。诸如烟斑病（几种真菌的复合体）和蝇斑（Zygophiala jamaicensis Mason）等病害是对果实造成损害的主要来源。'Golden Delicious' 树的未损坏果实的百分比高于'York'，但是所有的树都有一定比例的受损果实。在对照（未喷洒）和杀虫剂处理中，损害最为严重，在整体处理中处于中等水平，而在抗微生物和抗微生物 + 杀虫剂处理中则低得多（p
