The Organizing Committee cordially invites you to the 13th World Congress on Parasitic Plants (WCPP13) to be held from 5-10 July 2015 in Kunming, the City of Eternal Spring, in Southwest of China mainland. Organized by Kunming Institute of Botany (KIB), Chinese Academy of Sciences (CAS) under the auspices of the International Parasitic Plant Society (IPPS), this 6 day event would bring the WCPP legacy to East Asia for the first time. WCPP13 will continue the long tradition of regularly assembling experts on parasitic plants from all over the world for academic meetings that started in 1973 in Malta. With the theme “Parasitic plants: the good, the bad, and the mysterious”, this congress seeks to stimulate a productive exchange of information and ideas among researchers from around the world representing a wide spectrum of disciplines and perspectives, but all focused around the common theme of plant parasitism. Conference sessions will be designed to find common interests and to include presentations of the cutting edge of parasitic plants research (concerning both weedy and non-weedy species) and of management technologies of parasitic weeds. The ultimate objectives of WCPP13 can be summarized as “Concern, Control, and Collaboration”, and our meeting activities reflect these three elements: Concern in what we hope to raise more concern on currently non-weedy parasitic plants before they become a problem; Control in the activities that we are developing new technologies and applications for a better management of parasitic weeds; and Collaboration, the hallmark of WCPP13 permeating through all our activities. We are looking forward to meeting researchers from all over the world for an exciting and varied scientific program. In addition to an engaging scientific program, attendees will enjoy a range of diverse social events as well as Kunming’s many attractions, including a visit to Yunnan Ethnic Village that showcases the culture and customs of all the ethnic groups in Yunnan Province. We hope that you will take the opportunity to socialize and network with new acquaintances, and build upon those relationships which have already been established to sustain our collaboration. Please consider attending the 13th World Congress on Parasitic Plants. Mark the date in your calendar and register for the Congress. On behalf of the Organizing Committee and the Society, we are looking forward to meeting you in Kunming.
