摘要:

根肿病(clubroot disease)是十字花科蔬菜生产中的毁灭性病害,近年来在我国大面积发生,明确根肿病的侵染途
径和防治方法对于十字花科蔬菜生产具有重要意义。本试验通过对育苗基质人工接种芸薹根肿菌,发现基质带菌可导致十字
花科根肿病的发生,且带菌量越多根肿病发生越严重。在基质带菌量(芸薹根肿菌休眠孢子)为3×103 个·mL-1 的条件下,
采用基质拌药法测定7 种药剂消毒育苗基质对大白菜和花椰菜根肿病的防治效果。结果表明:50% 氟啶胺悬浮剂和10% 氰
霜唑悬浮剂对根肿病的防治效果最好,防效均达到100.00%,而且对大白菜和花椰菜幼苗安全,可以作为基质消毒防治根肿
病的药剂。

Abstract:

Clubroot disease,caused by Plasmodinophora brassicae, is a destructive disease for cruciferous
vegetables.Recently,this disease occurred in China by large areas.It is of important significance for cruciferous
vegetables production to clarify the infection ways and controlling methods of clubroot disease.In this study,
the seedling substrates were artificially inoculated with clubroot pathogen.The results showed that the substrate
carrying clubroot pathogen could lead to the occurrence of clubroot disease.And the more pathogen population in
substrate,the more serious was clubroot disease.Moreover,in the presence of 3×103 dormant spores per mL in
the substrate,the control efficiency of 7 kinds substrate with disinfectants against Chinese cabbage and cauliflower
clubroot pathogens were determined.The results also indicated that 50% fluridamine suspension and 10%
cyperazole suspension had the best control effect on clubroot diseases.The control effect could reach 100.00%.
These 2 chemical agents were safe for Chinese cabbage and cauliflower seedlings and could be used as substrate
disinfectants to control clubroot disease.
