This publication deals with appropriate maturity indices and postharvest handling for fresh-market peaches to educate producers, pickers, packers, and shippers about how to reduce peach postharvest losses and prevent quality deterioration, recalls, and subsequent loss of value during the production and trade of peaches in the region.

Pulse width modulation (PWM) technology is becoming a standard option on most new agricultural sprayers because of its ability to precisely regulate both flow rate and pressure over a wide range of travel speeds. This publication provides information on nozzle selection for sprayers equipped with PWM technology, including how to use PWM nozzle selection/tabulation charts, other useful online tools, and considerations for effective pesticide applications.

In 2010, the UGA cotton agronomists implemented this variety testing program. Our industry partners were asked to provide their most well-suited varieties for Georgia. Historically, the varieties evaluated in this trial have accounted for nearly 75% of the planted acreage in Georgia in the same year. These varieties were planted in replicated trials in growers’ fields throughout cotton-producing regions of Georgia, through coordination with the county Extension agents. The trials were managed and replicated by the grower with the assistance of the coordinating county agent to achieve realistic and statistically sound results.

Soil Organic Matter
Soil organic matter (SOM) is a complex mixture of plant and animal tissues, and plays an important role in the physical, chemical, and biological processes in the soil. This publication describes how SOM contributes to overall soil fertility, factors controlling SOM abundance, and what cultivation practices growers can use to increase SOM in their soils.

Drought can have a double impact on cattle producers. Not only is forage limited during the grazing months, but also the production of hay is limited. With the lack of forage, both grazed and conserved, many producers are looking for sources of feed for their cattle going into the fall and winter. Hay is an option, but it’s not the only option. Hay replacement rations can be an economical option to purchasing additional hay. Grains are often cheaper per unit of energy than hay, especially when hay prices increase during a drought period.
When considering these feeding options, producers should consider three major issues: 1. Cost of the potential feeds and their nutrients, 2. Which rations will meet the nutritional requirements of their cattle, and 3. How to properly feed cattle with the hay replacement ration.|

One of the most common questions regarding citrus is how much cold weather they can withstand before they are killed. Most citrus growers are looking for a specific low temperature, but there is no simple answer to this question because there are so many factors involved in citrus cold hardiness. This publication details research and information on the relative cold hardiness of different citrus varieties in Georgia documented from the 2022 December freeze, which saw unseasonably low temperatures. It is important to document the impact of a freeze such as this one on citrus varieties as they are a long-term investment and should be chosen carefully. Additional authors include: Danielle Williams, Mark Frye, Derrick Bown, Jason Edenfield, Justin Shealey, Ben Reeves, Holly Anderson, Tucker Price, Braxton Crews, and Kim Post.

With over 6,000 species world-wide and 812 in the United States and Canada, hover flies (Diptera: Syrphidae), also known as flower flies or syrphid flies, are a highly diverse, common, and charismatic family of insects which provide a broad diversity of ecosystem services including pollination, biological control, and decomposition that benefit humans. Despite this, these insects are largely unnoticed, misidentified, or are misunderstood by many members of the public largely due to their tendency to mimic bees and wasps. The goal of this publication is to alleviate this “hover fly blindness” by informing readers about the importance of these magnificent insects and providing a brief guide to common species found in the southeastern United States, specifically the state of Georgia.

Private well waters often contain high levels of iron, manganese, and hydrogen-sulfide. While these contaminants are not considered to have any human health consequences, they can cause various issues such as staining, impaired taste, and odor problems once their concentration exceeds certain levels, and homeowners need an appropriate system to remove them—such as an oxidizing filter. Oxidizing filters operate using oxidation, which occurs when a substance comes into contact with oxygen or another oxidizing substance. Everyday examples of oxidation are rust and the brown color that develops on a cut apple. This publication discusses various aspects of oxidizing filtration technique such as applicability, types of filter media, maintenance, etc.
