Biological Control of Tomato Bacterial Wilt Caused by Ralstonia solanacearum with Erwinia persicinus RA2 and Bacillus pumilus WP8
摘要
Abstract
The effect of Erwinia persicinus RA2 and Bacillus pumilus WP8 with soaking and mixing soil treatments on tomato bacterial wilt and tomato rhizosphere bacterial community were studied.The results showed that both E.persicinus RA2 and B.pumilus WP8 could effectively control tomato bacterial wilt,and promote growth of tomato seedlings.Inoculation method with the seeds soaking was more effective than soil drench.The rates of healthy stand treated by seeds soaking were 68.9% and 62.8% respectively,significantly higher when compared to control and Ralstonia solanacearum QL-Rs1115 treatment;The dry biomass of stem and leaf and root reached 4.87 mg·strain^-1 and 35.69 mg·strain^-1 in B.pumilus WP8 soaking treatment,which were improved by 110.82% and 205.83% compared to R.solanacearum QL-Rs1115 treatment;Also,soil aggregate stability（〉0.25 mm） ratio were increased 269.91% and 156.88% compared to control and R.solanacearum QL-Rs1115 treatment respectively.DGGE fingerprinting indicated that the uses of E.persicinus RA2 and B.pumilus WP8 had minimal effects on rhizosphere bacterial community.关键词
