Ethylenediurea (EDU) has been widely used to prevent ozone (O(3)) injury and crop losses in crop plants and growth reductions in forest trees. Successful use requires establishing a dose/response curve for EDU and the proposed plant in the absence of O(3) and in the presence of O(3) before initiating multiple applications to prevent O(3) injury. EDU can be used to verify foliar O(3) symptoms in the field, and to screen plants for sensitivity to O(3) under ambient conditions. Despite considerable research, the mode of action of EDU remains elusive. Additional research on the mode of action of EDU in suppressing O(3) injury in plants may also be helpful in understanding the mode of action of O(3) in causing injury in plants.
乙撑脲（EDU）已被广泛用于防止农作物臭氧（O(3)）损伤和减产，以及减少森林树木生长减缓。成功使用需要在不存在臭氧和存在臭氧的情况下，为 EDU 和拟议植物建立剂量/反应曲线，然后再进行多次应用以防止臭氧损伤。EDU 可用于验证田间叶片臭氧症状，并在环境条件下筛选对臭氧敏感的植物。尽管进行了大量研究，但 EDU 的作用模式仍然难以捉摸。对 EDU 抑制植物臭氧损伤作用模式的进一步研究，也有助于了解臭氧引起植物损伤的作用模式。
