摘要
利用2种植物免疫剂对绿豆晕疫病的防治效果进行了研究。结果表明,植物免疫剂JM2号原液和稀释液(2倍稀释)对绿豆晕疫病菌(Pseudomonas syringae pv.phaseolicola)菌落生长的抑制率高达100%,JM1号植物免疫剂无抑制作用。在盆栽植株上进一步研究了2种植物免疫剂对绿豆晕疫病的防治作用。结果表明,感病的绿豆植株第一次喷JM1和JM2号植物免疫剂,第一次喷药14 d后的防治效果分别为26.67%和39.82%;第二次喷药14 d后的防治效果分别为21.43%和15.35%。随着感病天数增加,植物免疫剂JM1和JM2号的防治效果均降低。由此可见,植物免疫剂JM1号和JM2号原液对绿豆晕疫病均具有一定的防治效果,与其他药剂配合使用,可在农业生产上对防治绿豆晕疫病进行推广应用。
The control effects of two plant immune agents on halo blight of Vigna radiata L were studied.The results showed that the plant immune agent JM2 original extract and dilution(2-fold dilution)inhibited the growth of colonies of Pseudomonas syringae pv.Phaseolicolaon NA medium.The JM1 plant immune reagent didn’t show any inhibition effect.The effects of two plant immune agents on the control of halo blight of Vigna radiata L were further studied on plants in soil.When the plants were sprayed by Pseudomonas syringae pv.Phaseolicola on for 14 days,the control effects of JM1 and JM2 plant immune agents on halo blight of Vigna radiata L plants was 26.67%and 39.82%respectively.We performed the second spraying treatment with plant immunity agents,the control effects were 21.43%and 15.35%,respectively14 days later.We found that the control effects of the plant immune agents JM1 and JM2 decreased with the time of bacteria spraying.We suggested that the plant immune agents JM1 and JM2 had certain control effects on Vigna radiata L.and could be used together with other agents against diseases in the field.
