Abnormal weather conditions such as warmer temperatures and reduced day light affected normal plant growth and reduced yields. Citrus producers in Peru are well organized and, in the most part, use a high level of technology.

There are two citrus organizations in Peru. Procitrus which is a non profit producer’s organization that is mainly devoted to issues regarding relationships with the central government and SENASA (the Peruvian SPS authority) as well as training. The other organization is CPF (Consorcio de Productores de Fruta), a trading company established by over 50 producers. CPF markets and exports both member and non member’s product.
