[Experimental research on molluscicidal effect of endophyte JJ18 from Pseudolarix amabilis].
OBJECTIVE
To research molluscicidal effect activity, active components and stable passage of endophyte JJ18 from Pseudolarix amabilis and examine the possibility for practical application.


METHODS
Molluscicidal effect test was performed according to the immersion test method suggested by WHO.


RESULTS
Immersion test with JJ18 broth showed that the active components were extracellular moiety of the broth and that 10% concentration solution could kill nearly 90% snail immersed after 72 h, the salified broth has favourable thermostabily and photostability and showed that JJ18 has stable passage and its active components concentrate in the extract of n-butanol.


CONCLUSIONS
The metabolite of endophyte JJ18 has activity for molluscicidal effect and potential for application.
