Abstract ISSN 0967­0874 A survey for pathogens of Chromolaena odorata was conducted in Trinidad and Tobago over a 24­month period. The rust Cionothrix praelonga was reported in Trinidad for the first time, DOI 10.1080/09670879309371829 where it was found at two sites in Temple Village, Armina and on the Macqueripe Road,

Chaguaramas. No seasonal fluctuation in the incidence of the disease was observed in the Language of Text field during the 2­year study. The optimum conditions for infection were established and English infection was achieved with laboratory­inoculated plants. Young leaves appeared to be more susceptible to infection than older tissues. The following three plant pathogenic fungi were Language of Summary identified as potential biological control agents: Septoria ekmaniana, Anhellia niger, and English Mycovellosiella perfoliata. Host specificity screening trials using 16 local composite weeds Geographical Location [family Asteraceae] known to be closely related to C. odorata indicated that C. praelonga was Trinidad and Tobago strictly host­specific while S. ekmaniana showed a very restricted host range. The potential for pathogens as biological control agents of C. odorata is discussed.
