Abstract: To determine the biological activity of Bursaphelenchus xylophilus with the live immersion method,three ethanol extraction of the roots,stems,and flowers of the marigold plant(Tagetes erecta) was used. A gradient test design with seven treatments of 1.000,0.500,0.100,0.050,0.010,0.001 and 0 gL-1 with four replications were established to immerse B. xylophilus (100 number in one culture dish,28 ℃). After 72 h,death rate of B. xylophilus was determined. Results showed that ethanol extracts immersed for 72 h had a corrected death rate for B. xylophilus of >60%. From among the three plant parts,ethanol extracts coming from the marigold roots had the greatest success with a corrected death rate for B. xylophilus>90%. Also,the ratio of the three extracts to the raw materials was>5%. Thus,we believe marigold plant extracts could be used to control B. xylophilus.[Ch,1 fig. 1 tab. 13 ref.]
