The application of disinfectants through drip irrigation could be a feasible practice against verticillium wilt (Verticillium dahliae) of olive. OX‐VIRIN (activated peroxide) and OX‐AGUA AL25 (quaternary ammonium compounds) are two disinfectants that have shown efficacy against V. dahliae in irrigation water and potential for reducing the disease in young olive plants. In this work, various post‐planting application strategies incorporating OX‐VIRIN (once a month, or twice a month on alternate or successive weeks) or OX‐AGUA AL25 (once a month, or twice a month on alternate weeks) were assessed for their effect on V. dahliae in soil, disease in olive trees, and olive yield, in a 2‐year pot‐experiment under natural environmental conditions. The disinfectants were injected via metering pumps into a drip irrigation system that irrigated olive trees planted in V. dahliae‐inoculated soil. All the application strategies significantly reduced the total inoculum density in soil compared to controls with no disinfectants and noninoculated soil. The microsclerotia density was also significantly reduced in disinfested soils by 73.6–86.8%, depending on the strategy. The symptoms and infection incidence were always lower in treatments subjected to disinfestation. The treatment with OX‐AGUA AL25 applied twice a month on alternate weeks most reduced the symptoms (by 53.0%) and colonization index (by 70.8%) with respect to untreated water control. This soil disinfestation also significantly strengthened the symptom remission. Tree growth and production were negatively affected by soil inoculation (reduced by 45.6% and 88.7%, respectively), but not so by disinfectants, which even relieved the reduction in inoculated soils, especially when OX‐AGUA AL25 was applied.

通过灌溉向土壤中施用消毒剂，可减少土壤中的黄萎病菌和橄榄黄萎病

通过滴灌施用消毒剂可能是一种针对橄榄黄萎病（Verticillium dahliae）的可行方法。OX-VIRIN（活化过氧化物）和OX-AGUA AL25（季铵化合物）是已经显示出功效针对两种消毒剂黄萎病菌在灌溉用水和潜在的用于减少年轻橄榄植物疾病。在这项工作中，评估了各种结合了OX-VIRIN（每月一次，或隔周或连续两周每月两次）或OX-AGUA AL25（每月一次，或隔周隔两个月，两次）的种植后施用策略。它们对大丽花弧菌的影响在自然环境条件下进行的2年盆栽试验中，土壤，橄榄树上的病害和橄榄的产量降低了。通过计量泵将消毒剂注入滴灌系统，该系统灌溉了大丽花种植的橄榄树接种过的土壤。与没有消毒剂和未接种土壤的对照相比，所有施用策略均显着降低了土壤中的总接种密度。灭虫土壤中的菌核​​密度也显着降低了73.6–86.8％，具体取决于策略。在进行灭虫的治疗中，症状和感染发生率始终较低。与未经处理的水质控制相比，每月两次交替施用OX-AGUA AL25的治疗最多可减轻症状（53.0％）和定殖指数（70.8％）。这种土壤除虫也大大增强了症状缓解。树木的生长和产量受到土壤接种的负面影响（分别减少了45.6％和88.7％），但消毒剂却没有，这甚至减轻了接种土壤的减少，
