Abstract:

The stumps of the dead wood caused by Bursaphelenchus xylophilus (PWN) were one of the most important infection source of pine wilt disease. Effective measure taken to treat stumps would be helpful to improve efficiency to control the disease. In this study, Laetiporus sulphureus strain 6600, Coriolus versicolor strain 6923, Fomitopsis pinicola strain W11, Poria cocos strain 6284 and Pleurotus ostreatus strain 6221 were chosen to treat stumps of the dead wood caused by PWN, the ability of decomposing stumps and the effects of PWN were studied in this paper. The results showed that the strain of 6600 had the highest ability to decompose stumps and certain nematicidal effects on PWN. The correlation analysis indicated that the number of PWN had significant and positive relation with the weight of stumps. The study sets important basis of using woodrotting fungi for treating stumps of the dead wood in the future.
