چکیده
|
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.
