Foodborne Illnesses
Foodborne illnesses sicken approximately 48 million Americans a year and result in significant financial losses for the food industry. Outbreaks of foodborne illness have been linked to consumption of small fruit products, but growers and packers can take precautions to reduce food safety risks on their operations. This video discusses what foodborne illnesses are, what causes them, and basic steps that can be taken to ensure the production of safe fruit. This video was produced in collaboration with the Auburn Department of Horticulture.

2021 plant disease losses, including control costs, amounted to an estimated $889 million. The value of the crops used in this estimate was approximately $7690 million, resulting in a 11.6% relative disease loss across all crops included in this summary. For most crops, the estimated values used to compute these disease losses are summarized in the UGA Center for Agribusiness & Economic Development’s “2021 Georgia Farm Gate Value Report” (AR-22-01). Some estimates for fruits, ornamentals, and turf rely on specialists’ knowledge of the industry and industry sources for information.

As pecan trees grow in an orchard, their tree canopies encroach upon one another, causing excessive shading, which can increase alternate bearing intensity and reduce tree health and orchard profitability. Historically, limb pruning and tree removal have been the most common methods of dealing with this problem, particularly in the low-light environment of the southeastern United States. Mechanical hedge pruning has been used successfully in high-light environments to mitigate the effects of orchard shading and has become the standard method used for this purpose in the arid production regions of the western United States. The southeastern United States is a relatively low-light environment, exhibiting significant cloud cover and atmospheric water vapor throughout the growing season, which can further limit sunlight in orchard systems. Mechanical hedge pruning offers a solution to this problem, which can also help minimize issues related to pecan scab, hurricanes/tropical storms, and alternate bearing.

Blueberry Production
This publication covers a brief history of the development of blueberries, plus general production requirements such as varieties, chill hours, soil considerations, etc. The southern highbush blueberry is a hybrid that requires fewer chill units compared to northern highbush types, allowing the state of Florida, southern areas, and Georgia to produce fruits in the U.S. market during March, April, and May. The development of southern highbush also has allowed the production of blueberries in countries such as Mexico and Peru.

Los Arándanos y Su Producción
El arándano alto del sur, es un híbrido que requiere pocas horas de frio—una aproximación de cuantas horas la planta requiere estar expuesta a temperaturas de entre 32 a 45 °F para romper la dormancia y empezar iniciación floral—comparado con el arándano alto del norte. Por lo que permite al estado de Florida y áreas del Sur de Georgia posicionarse en el mercado estadounidense en los meses de Marzo, Abril y Mayo, y es el que ha permitido la producción de arándanos para exportación en países como México y Perú.
