ABSTRACT Plant–parasitic nematodes diminish the yield of tomato crops worldwide. Irrigation water may be contaminated with such parasites, including Meloidogyne enterolobii. In this study, ozone treatment was applied to inactivate M. enterolobii eggs. Eggs were rendered inviable in water after exposure to 0.55 mgO3 L−1 ozone residual for 15 min. Additionally, the effect of temperature, alkalinity, and organic matter of the water were evaluated. The results showed that ozonation is an effective and promising alternative method for nematode control in irrigation water, which could reduce tomato crop infestation caused by plant–parasitic nematodes.

使用臭氧消毒灌溉水改良番茄作物

摘要 植物寄生线虫降低了全世界番茄作物的产量。灌溉用水可能被此类寄生虫污染，包括肠根结线虫。在这项研究中，臭氧处理用于灭活肠杆菌卵。在暴露于 0.55 mgO3 L−1 臭氧残留 15 分钟后，鸡蛋在水中无法存活。此外，还评估了水的温度、碱度和有机物的影响。结果表明，臭氧化是一种有效且有前景的灌溉水中线虫控制替代方法，可减少植物寄生线虫对番茄作物的侵染。
