LATEST PSI NEWS

The 2024 conference was held in Europe, so for 2025 it is America’s turn, and we’d been thinking of holding it in Brazil, building on our contacts from the study trip.

However an alternative has now arisen, to hold it in Medellin, Colombia, where the Colombian Passiflora Export Association plans to hold its 3rd World Congress in Medellin in early April or May 2025. The Association is a trade body, but the congress will also include academic presentations, farm visits and other items of interest. PSI could participate in some or all of these, and afterwards have its own events, such as mini-field trips.

This seems an interesting opportunity, but do you agree ?

To let us know, please log in and let us know your preferences in the short form you will find here. We need your answers as soon as possible, please, and in any event BY THE END OF SEPTEMBER.
