2018 PGRSA Annual Conference

    The 45th Annual PGRSA Conference will take place in San Juan, Puerto Rico from June 10 - 14, 2018. Technical sessions will cover a broad range of topics critical to the plant growth regulation industry, including plant growth in extreme environments, light as a growth regulator and PGRs and biostimulants. The conference will include oral and poster presentations of scientific research and provides the ideal opportunity for leaders in the applied, basic and commercial fields of plant growth regulation to exchange ideas and review presentations.

    Attendees also can visit a variety of local attractions, including the San Felipe del Morro Fortress — a 16th century citadel — and Historic Old San Juan. We also suggest a visit to the USDA's Tropical Agricultural Research Station and a hike through the El Yunque Rainforest.

In exchange, the host hotels offer us concessions and other perks. If we fail to meet our room night commitments, we are faced with hefty penalty fees.
