| 摘 要： | 依据青花菜根肿病的发生特点,采用穴盘育苗时药液拌基质及移栽后不同时期灌根的方式,研究50%氟啶胺悬浮剂(SC)不同施用方法对青花菜根肿病的防治效果以及苗期和成株期植株生长的安全性。结果表明:基质拌50%氟啶胺SC1 000、2 000、3 000倍液处理对青花菜出苗率没有明显影响,但均抑制幼苗生长,与对照相比株高变矮、第1片真叶变短,药剂浓度越高抑制作用越明显,故不宜在育苗期使用该药剂。移栽后不同时期50%氟啶胺SC 1 000倍液灌根处理对青花菜根肿病防效显著,移栽后3 d和30 d灌根处理的防治效果最佳,相对防效达到92.21%,极显著优于其他处理;其次是移栽后3 d灌根处理,相对防效为74.03%,极显著优于发病后灌根处理;药液2次灌根处理的防治效果优于1次灌根处理,根肿病显症前灌根处理的防治效果优于显症后灌根处理。

| Abstract: | According to the characteristics of clubroot occurrence in broccoli，this paper studied the control
effect of 50% fluazinam suspension（SC）on clubroot and safety for plant growth in seedling and adult-plant stages
by 2 different applying methods：one was homogeneously stirred seedling substrate while sowing，the other was
root-irrigation at different dates after transplanting in field．The results showed that the growth of seedling was
inhibited severely by 3 concentrations of 50% fluazinam SC．Compared with the control group，the plant height
became shorter，and first true leaf became smaller．The higher the concentration was，the more obvious the
inhibition was．So fluazinam was not suitable to be used in the seedling stage．Meanwhile，the rate of emergence
was not significantly affected．The control effect was variant，as applying 50% fluazinam SC irrigating root aftertransplanting in field at different dates．The relative control effect of treatment with root-irrigation at 3 days and
30 days after transplanting was extremely the best，reaching 92.21%，which was extremely significantly superior
to the other treatments．The second way was conducting root- irrigation at 3 days after transplanting．The relative
control effect was 74.03%，which was extremely significantly better than that after disease onset．The control
effect of the treatment of 2 times was obviously better than that of the treatment of 1 time．Meanwhile，the control
effect of treatment before symptom appeared was better than that of the treatment afterwards． |
