The California Freestone Peach Association (CFPA)[2] and California Canning Peach Association/California Cling Peach Board (CCPA)[2][3] represent the industry.[4] (Although the CFPA is a separate incorporation, it has always been operated by the CCPA's staff.) The overwhelming majority of the country's peaches are grown here, in 2020 468,000 short tons (425,000 t) for sales of $308.3 million.[5] Since 1980 the total value of the harvest has been slightly increasing.[5] The acreage (hectares) planted in peach has been declining however, down to 73,000 acres (30,000 ha) as of 2020.[5]

Economics

edit

In 2014, California lead US peach production, followed by South Carolina, then Georgia.[6]

As of 2021 cling deliveries for processing purposes have been on a downward trend for years.[7] From 430,000 short tons (390,000 t) in 2010, delivered tonnage declined to 225,000 short tons (204,000 t) in 2021.[7] Cling yield shows no clear trend over the same time, bouncing between 18.1 short tons per acre (41 t/ha) and 15.3 short tons per acre (34 t/ha).[7]

Prices have been trending mostly upward, from $317 per short ton ($349/t) in 2012 to $518 per short ton ($571/t).[7]

CCPA expects 2022 deliveries to be between 214,200–232,400 short tons (194,300–210,800 t) from a yield of 15.3–16.6 short tons per acre (34–37 t/ha).[7]

Breeding of peach

edit

UCD hosts one of the major breeding programs in the country.[8] Most of the private breeding programs for peach in the country are found in California, with a significant amount of the public breeding also being performed here but also elsewhere in the country.[8]

Cultivars of peach

edit

UCANR recommends[9] cultivars for the state:

Pests of peach

edit

See Cal ag § Colletotrichum acutatum for the cause of Peach Anthracnose here.[14]

Diseases of peach

edit

The most common unicellular diseases are:[15]

UC IPM provides information about commonly used fungicides[16] and fungicide efficacy. (See also Cal ag § Fungicides.)

Peach Yellow Leaf Roll was first discovered in the Sacramento Valley in 1948, but remained uncommon until an epidemic in the late 1970s and early 1980s.[17] For the causative organism see Cal ag § Candidatus Phytoplasma pyri.

Nematode diseases of peach

The most common nematode diseases are:[18]

Integrated pest management in peach

edit

Regional Integrated Pest Management Centers (Regional IPM Centers) hosts a suggested IPM plan for peach.[19] UC IPM provides even more detailed integrated pest management information.[15]

Fungal disease IPM in peach

edit

UC IPM recommends treatment timings[20] and resistance management practices[21] specifically for peach IPM.
