Research progress on nematode diseases of lily and their integrated management
In this paper,the species,distribution,damage level and control methods of lily-associated plant nematodes were reviewed.40 nematode species and 12 unidentified species belonging to 3 orders,15 fam-ilies and 22 genera were reported on lily worldwide,in which only 7 species were recorded in China.Lily-related nematodes were abundant in the United States and the Netherlands,with 20 and 11 species reported respectively.Aphelenchoides fragariae,Aphelenchoides ritezemabosi,Pratylenchus penetrans and Dity-lenchus dipsaci are the most important parasitic nematodes of lily,the pathogenicity and control methods of these four plant nematode species were well studied.The integrated managements for effective control nematode diseases of lily were planting stock selection,field management,hot water treatment,crop rotation and chemical control.The research direction of nematode diseases of lily in China was also discussed in this paper,which will provide an important reference for the investigation and control of lily nematode dis-eases in the future.
