Peroxyacetic acid mixture Perosan, composed of peroxyacetic acid, hydrogen peroxide and acetic acid, was evaluated for eco-friendly management of tomato bacterial wilt by Ralstonia pseudosolanacearum. Perosan drastically suppressed in vitro growth of R. pseudosolanacearum in liquid cultures in dose- and incubation time-dependent manners. Higher perosan doses (0.1 and 1%) caused lowered pH and phytotoxicity to detached leaves of two tomato cultivars Cupirang and Benekia 220 in aqueous solution. Treatment with 0.01% of Perosan delayed wilting symptom significantly in the detached leaves of two cultivars inoculated with R. pseudosolanacearum (10⁷ cfu/ml). Soil drenching of 5% Perosan solution in pots caused severe tissue collapse of tomato seedlings at the four-week-old stage of two tomato cultivars. Treatment with 1% Perosan by soil-drenching significantly reduced bacterial wilt in the tomato seedlings of two cultivars. These findings suggest that Perosan treatment can be applied to suppress bacterial wilt during tomato production.

杀菌过氧乙酸混合物处理可减少番茄中的细菌枯萎病。

过氧乙酸混合物Perosan，过氧乙酸，过氧化氢和乙酸的组成，评价了由番茄青枯病的生态友好的管理青枯pseudosolanacearum。Perosan大幅度地抑制了在体外的生长R. pseudosolanacearum在剂量和温育时间依赖性液体培养物。较高的Perosan剂量（0.1和1％）会降低水溶液中两个番茄品种Cupirang和Benekia 220离体叶片的pH值和植物毒性。与Perosan的0.01％在治疗接种两个品种的离体叶片显著延迟萎蔫症状R. pseudosolanacearum（10 ⁷cfu / ml）。在两个番茄品种的四周龄阶段，盆中5％Perosan溶液的土壤淋湿会导致番茄幼苗严重组织塌陷。通过土壤灌溉用1％的Perosan处理可以显着减少两个品种番茄幼苗中的细菌萎。这些发现表明，Perosan处理可用于抑制番茄生产过程中的细菌枯萎。
