Abstract The effectiveness of NuovOlivo®, a natural detergent made from plants oils and extracts of multi botanical species plus sodium and calcium hydroxide, and sulphur activated with sodium bicarbonate (patent n. 102017000109094 Ministero dello Sviluppo Economico, Italy) was tested in the control of Olive Quick Decline Syndrome associated with Xylella fastidiosa subsp. pauca. Tests were conducted in two naturally infected olive groves located in the province of Lecce, Apulia, Italy). The first experiment included 70 to 75-year-old olive trees cv Cellina di Nardo, in Montesano Salentino. Here the percentage of McKinney's disease index was reduced to 2.5% and plants produced drupe fruits after seven treatments. Olive trees were sprayed twice per year (in March and October) and pruned in winter. The second experiment included 60 to 65-year-old olive trees cv Ogliarola salentina growing in Sternatia which initially showed a disease index of 90.88%. This figure was reduced to 4.0% after two years of three spray treatments. In both olive cultivars, qRT-PCR resulted in lower levels of X. fastidiosa DNA in the treated trees. The leaves of treated plants showed a low total phenolic content and no cell membrane damage associated to lipid peroxidation and electrolyte leakage. NuovOlivo® works as a curative product limiting and/or stopping the destructive epidemic caused by this bacterium.

探索一种可持续的解决方案来控制意大利南部萨伦托半岛橄榄上的难养木霉亚种

摘要 NuovOlivo® 是一种由植物油和多种植物提取物加氢氧化钠和钙以及用碳酸氢钠活化的硫制成的天然洗涤剂（专利号 102017000109094 意大利部长级经济部长）的有效性在控制Olive Quick Decline Syndrome 与 Xylella fastidiosa subsp. 相关。保卡。测试是在位于意大利普利亚莱切省的两个自然感染的橄榄园中进行的）。第一个实验包括在 Montesano Salentino 种植 70 至 75 岁的橄榄树 cv Cellina di Nardo。在这里，麦金尼病指数的百分比降低到 2.5%，经过 7 次处理后，植物产生了核果。橄榄树每年喷洒两次（3 月和 10 月），并在冬季修剪。第二个实验包括生长在 Sternatia 的 60 至 65 岁橄榄树 cv Ogliarola salentina，最初显示的疾病指数为 90.88%。经过两年的三次喷雾处理后，这个数字降低到 4.0%。在这两个橄榄栽培品种中，qRT-PCR 导致处理过的树木中的难养葡萄球菌 DNA 水平较低。处理过的植物的叶子显示出低总酚含量并且没有与脂质过氧化和电解质泄漏相关的细胞膜损伤。NuovOlivo® 作为一种治疗产品，可以限制和/或阻止由这种细菌引起的破坏性流行病。处理过的树木中的 fastidiosa DNA。处理过的植物的叶子显示出低总酚含量并且没有与脂质过氧化和电解质泄漏相关的细胞膜损伤。NuovOlivo® 作为一种治疗产品，可以限制和/或阻止由这种细菌引起的破坏性流行病。处理过的树木中的 fastidiosa DNA。处理过的植物的叶子显示出低总酚含量并且没有与脂质过氧化和电解质泄漏相关的细胞膜损伤。NuovOlivo® 作为一种治疗产品，可以限制和/或阻止由这种细菌引起的破坏性流行病。
