自1969-1970年以来，日本每年都会发生光化学氧化剂污染和相关的植物伤害事件。光化学氧化剂（主要是臭氧）对作物的伤害与农业经济损失直接相关。特别是叶菜类蔬菜，受损后其商品价值大大降低，造成了巨大的经济损失。考虑了避免臭氧造成损害的五种农业技术方法：（1）作物的遗传抗性特性;（2）肥料管理;（3）用特定化学品处理;（4）防御基因的生物技术激活;（5）设施内栽培。然而，到目前为止，这些方法只提供了一个临时的对策，提供有限的保护，并仅适用于发生轻度伤害。
Photochemical oxidant pollution and related occurrences of plant injury have occurred in Japan every year since 1969-1970. Crop injury by photochemical oxidants (mainly ozone) is directly connected with agricultural economic loss. Especially, the marketable values of damaged leafy vegetables are greatly reduced, causing drastic economic losses. Five methods of agriculture technology for avoiding damage resulting from ozone are considered: (1) inherited resistance properties of crops; (2) fertilizer management; (3) treatment with specific chemicals; (4) biotechnological activation of defense genes; and (5) in-facilities cultivation. However, until now these methods only offer a temporary countermeasure, providing limited protection and are useful only against occurrence of mild injuries.
