The ISCN Congress is fondly referred to as the University of Citrus Nurserying. Many of the top nurserymen in the world have been “educated” by networking with other nurserymen and scientists when attending the Congress at venues all over the world.

The Objectives of ISCN are as follows:

- To encourage and further the exchange of technical information and results of research pertaining to the propagation of citrus nursery trees and nursery industry related topics.

- To promote the production and use of citrus plants of quality which are true to type for the cultivar and have the maximum guarantee possible of freedom from pests and diseases.

- To promote the development of a programme for the exchange and introduction of citrus cultivars from one country to another by the use of technically prepared disease free propagation material.

- To compile comparative economic studies with the aim of providing stability in the marketing of citrus nursery products.

- To have Congresses every three to four years in various countries as determined by the members of the ISCN.

- To communicate regularly with all members of the Society.

ISCN Congresses are typically in 3 parts. A Pre-Congress, the Congress itself, and a post-Congress tour. The Congress focuses on scientific sessions related to the citrus nursery industry along with networking opportunities and a day of field tours. The Pre and Post Congresses are designed to be hands-on and offer multiple tours to commercial nursery operations as well as workshops where attendees can learn to adapt nursery technologies into their own operations.
