4种杀菌剂对油菜根肿病的防治潜力及对幼苗防御酶活性的影响
Preventive potential of 4 fungicides on clubroot (Plasmodiophora brassicae) and rapeseed defense enzyme activity
摘要
Abstract
Plasmodiophora brassicae is an important disease in rapeseed production.For better control,inhibition of 4 fungicides (fluazinam,oxine-copper,quintozene and carbendazim) against P.brassicae were detected with spore germination and pot experiments.Results showed that fluazinam (5.5mg/L) had the strongest inhibition on P.brassicae spore germination with inhibition rate of 38.1％,which was significantly higher than that of others.Oxine-copper,quintozene and carbendazim had 9.5-15.0％ inhibition rates,with no significant difference among them.In pot experiments,fluazinam (5.5mg/L) also had the strongest effects (86.1％) under root irrigation,which was significantly higher than that of others.Oxine-copper (0.62mg/L) had the efficacy of 73.2％.Quintozene and carbendazim had low effects.Among the 4 fungicides,defense enzyme activities of PAL (phenylalanine ammonialyase),POD (peroxidase) and PPO (polyphenol oxidase) were much higher in seedlings treated by 5.5mg/L fluazinam.Therefore,the efficacy of fluazinam on P.brassicae was worthy of further research in rapeseed production.关键词
