Production of peaches in California
California is the largest grower of peaches in the United States, producing about 70% of the total.[1]

The California Freestone Peach Association (CFPA)[2] and California Canning Peach Association/California Cling Peach Board (CCPA)[2][3] represent the industry.[4] (The CFPA is a separate incorporation that is operated by the CCPA's staff.) The 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] Peach acreage has been declining however, down to 73,000 acres (30,000 ha) as of 2020.[5]
In April 2026, Del Monte shut down its major warehouses in California. As of May 2026, California farmers plan on cutting down 420,000 peach trees following Del Monte's bankruptcy with $9 million of assistance from the United States Department of Agriculture.[6]
Economics
In 2014, California led US peach production, followed by South Carolina, then Georgia.[7]
As of 2021 cling deliveries for processing purposes have been on a downward trend for years.[8] From 430,000 short tons (390,000 t) in 2010, delivered tonnage declined to 225,000 short tons (204,000 t) in 2021.[8] 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).[8] As of 2022, prices of clingstone peaches had been trending mostly upward for several years, from $317 per short ton ($349/t) in 2012 to $518 per short ton ($571/t). In 2022, CCPA (California Canning Peach Association) expected deliveries of clingstone peaches 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).[8]
Breeding
UCD hosts one of the major breeding programs in the country.[9] 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.[9]

Diseases
Some diseases of peach in California include:[16][17]
- Armillaria Root Rot – see Cal ag § Armillaria Root Rot.
- Bacterial Canker (Pseudomonas syringae)
- Brown Rot Blossom and Twig Blight (Cal ag § Monilinia fructicola, occasionally Cal ag § Monilinia laxa)

UC IPM provides information about commonly used fungicides[18] 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.[19] For the causative organism see Cal ag § Candidatus Phytoplasma pyri.
Nematode diseases
Some nematode diseases of peach in California are:[20]
- Dagger nematode (Xiphinema americanum)
- Ring nematode (Mesocriconema xenoplax syn. Criconemella xenoplax)
- Root Lesion Nematode (Pratylenchus vulnus and other Pratylenchus spp.)
- Root-Knot Nematode (Meloidogyne arenaria, Cal ag § Meloidogyne hapla, Cal ag § Meloidogyne incognita, and Cal ag § Meloidogyne javanica)
Integrated pest management
Regional Integrated Pest Management Centers (Regional IPM Centers) hosts a suggested IPM plan for peach.[21] UC IPM provides even more detailed integrated pest management information.[16]
Fungal disease IPM
UC IPM recommends treatment timings[22] and resistance management practices[23] specifically for peach IPM.
