The almond is a species of tree from the genus Prunus. Along with the peach, it is classified in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell (endocarp) surrounding the seed.
Manihot esculenta, commonly called cassava, manioc, or yuca, is a woody shrub of the spurge family, Euphorbiaceae, native to South America, from Brazil, Paraguay and parts of the Andes. Although a perennial plant, cassava is extensively cultivated in tropical and subtropical regions as an annual crop for its edible starchy root tuber. Cassava is predominantly consumed in boiled form, but substantial quantities are processed to extract cassava starch, called tapioca, which is used for food, animal feed, and industrial purposes. The Brazilian farinha, and the related garri of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it.
An apricot is a fruit, or the tree that bears the fruit, of several species in the genus Prunus.
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.
A biopesticide is a biological substance or organism that damages, kills, or repels organisms seen as pests. Biological pest management intervention involves predatory, parasitic, or chemical relationships.
Radopholus similis is a species of nematode known commonly as the burrowing nematode. It is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas, and it can be found on coconut, avocado, coffee, sugarcane, other grasses, and ornamentals. It is a migratory endoparasite of roots, causing lesions that form cankers. Infected plants experience malnutrition.
Plum pox, also known as sharka, is the most devastating viral disease of stone fruit from the genus Prunus. The disease is caused by the plum pox virus (PPV), and the different strains may infect a variety of stone fruit species including peaches, apricots, plums, nectarine, almonds, and sweet and tart cherries. Wild and ornamental species of Prunus may also become infected by some strains of the virus.
Belonolaimus longicaudatus is a common parasite of grasses and other plant crops and products. It is the most destructive nematode pest of turf grass, and it also attacks a wide range of fruit, vegetable, and fiber crops such as citrus, cotton, ornamentals, and forage. The sting nematode is a migratory ectoparasite of roots. It is well established in many golf courses and presents a problem in turf management. The sting nematode is only present in very sandy soils. It cannot reproduce in heavier or clay soils.
Rotylenchulus reniformis, the reniform nematode, is a species of parasitic nematode of plants with a worldwide distribution in the tropical and subtropical regions.
Colletotrichum coccodes is a plant pathogen, which causes anthracnose on tomato and black dot disease of potato. Fungi survive on crop debris and disease emergence is favored by warm temperatures and wet weather.
Mesocriconema xenoplax is a species of plant parasitic nematodes. Nematodes of this particular species are collectively called ring nematodes.
Cherry mottle leaf virus (CMLV) is a plant pathogenic virus causing leaf rot. It is closely related to the peach mosaic virus.
Fusarium oxysporum f. sp. cubense is a fungal plant pathogen that causes Panama disease of banana, also known as Fusarium wilt. The fungi and the related disease are responsible for widespread pressure on banana growing regions, destroying the economic viability of several commercially important banana varieties.
Karen Bailey is a retired research scientist who specialized in plant pathology and biopesticide development at Agriculture and Agri-Food Canada. Her research focused on developing alternatives to synthetic pesticides and improving plant health through integrated pest management strategies. She is internationally recognized for her expertise on soil-borne pathogens and biological control, and she has more than 250 publications, 23 patents, and 7 inventions disclosures in progress.
Agriculture is a significant sector in California's economy, producing nearly US$50 billion in revenue in 2018. There are more than 400 commodity crops grown across California, including a significant portion of all fruits, vegetables, and nuts in the United States. In 2017, there were 77,100 unique farms and ranches in the state, operating across 25.3 million acres of land. The average farm size was 328 acres (133 ha), significantly less than the average farm size in the U.S. of 444 acres (180 ha).
Clavibacter insidiosus is a species of Clavibacter. It causes bacterial wilt, with its most notable host being Medicago sativa (alfalfa). Other species in the Medicago genus are also known to be hosts such as Medicago falcata. Additionally, Lotus corniculatus, Melilotus alba, Onobrychis viciifolia, and Trifolium sp. are known hosts.
Xanthomonas pruni is a bacterial disease of almost all Prunus.
California is the largest grower of peaches in the United States, producing about 70% of the total.
Strawberries in the United States are almost entirely grown in California – 86% of fresh and 98% of frozen in 2017 – with Florida a distant second. Of that 30.0% was from Monterey, 28.6% from Ventura, 20.0% from Santa Barbara, 10.0% from San Luis Obispo, and 9.2% from Santa Cruz. The Watsonville/Salinas strawberry zone in Santa Cruz/Monterey, and the Oxnard zone in Ventura, contribute heavily to those concentrations.
The 2020 table grape harvest was worth $2.12 billion while wine grapes brought in $1.7 billion, down 15.3% year-on-year. By weight this was 17% lower versus 2018. The next year, 2021 saw a much better yield. From 829,000 acres (335,000 ha) viniculturists got 6.94 short tons per acre (15.6 t/ha) for a total harvest of 5,755,000 short tons (5,221,000 t). At an average of $909 per short ton ($1,002/t) they were paid $5,229,902,000 for the season. Of that, 4,844,600 short tons (4,394,900 t) were for destined for processing industries and at $835 per short ton ($920/t) that was worth $4,046,382,000. The fresh harvest was 910,400 short tons (825,900 t) and selling at a price of $1,300 per short ton ($1,433/t), this sector was worth $1,183,520,000 for the season.
