Fast Facts
  • Citrus fruits are produced all over the world with 70% of production being in the Northern Hemisphere, particularly countries around the Mediterranean and the United States of America.
  • Although researchers believe that citrus fruits began to appear in South East Asia around 4,000BC, worldwide trade in the fruits did not appear until the 19th century and trade in orange juice did not develop until the 1940's.
  • An Integrated Fertiliser Program using RLF products can greatly enhance crop quality and yield.
  • Brazil is the largest producer of citrus fruits (predominately oranges) with almost 21 million tonnes. Almost all of Brazil's produce is exported.
  • China is the second largest producer of citrus fruits (predominately tangerines) with almost 20 million tonnes but it is for domestic use rather than export.
  • The United States of America is the third largest producer of citrus fruits with just over 10 million tonnes however 90% of this production supplies the home market.
  • The generally accepted grouping of Citrus Fruits includes the sub-sets of Oranges, Lemons and Limes, Grapefruit, Tangerines and 'All Others'.
  • About one third of citrus fruit production goes for processing – more than 80% of this for orange juice production. Internationally orange juice is traded in the form of frozen concentrate so as to reduce volume and for storage and transportation costs to be kept low.
  • Demand for both fresh and processed oranges continues to rise is excess of current production, especially in developed countries.
  • The two biggest export markets in citrus are based in Florida in the United States and in São Paulo in Brazil.
  • Citrus Canker, a bacterial disease which causes unsightly lesions on all parts of the plant and impacts tree health and yield, can often disrupt supply. Outbreaks in recent years in Australia, Brazil and the US have slowed citrus production.
