Peroxyacetic acid mixture Perosan, composed of peroxyacetic acid, hydrogen peroxide and acetic acid, was evaluated for eco-friendly management of tomato bacterial wilt by . Perosan drastically suppressed growth of 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 (10 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.
由过氧乙酸、过氧化氢和乙酸组成的过氧乙酸混合物Perosan，通过……被评估用于番茄青枯病的生态友好型治理。Perosan以剂量和培养时间依赖性方式显著抑制了液体培养物中……的生长。较高剂量的Perosan（0.1%和1%）会导致水溶液的pH值降低，并对两个番茄品种Cupirang和Benekia 220的离体叶片产生植物毒性。用0.01%的Perosan处理可显著延迟接种……（10 cfu/ml）的两个品种离体叶片的萎蔫症状。在盆栽中用5%的Perosan溶液进行土壤浇灌，导致两个番茄品种四周龄阶段的番茄幼苗出现严重的组织坏死。通过土壤浇灌1%的Perosan可显著降低两个品种番茄幼苗的青枯病发病率。这些结果表明，Perosan处理可应用于番茄生产过程中抑制青枯病。
