An acidified food is a low-acid food to which acids (such as vinegar, lemon juice, citric acid, etc.) or acid foods (such as fruits or tomatoes) have been added to bring the equilibrium pH of the food to 4.6 or less, with equilibrium water activity greater than 0.85.

Using Hot-Fill-Hold: A Thermal Preservation Process. Processors of acidified foods are required to comply with federal, state, and local regulations (when applicable) for thermal processing to ensure the safety and shelf-stability of their products. The hot-fill-hold (HFH) process is a thermal processing technique used to inactivate pathogens and extend the shelf life of acidified products. Heating before filling allows for commercial sterilization of the product, and then filling the container with the hot product will sterilize the clean container.

Rose rosette virus can cause major problems for nurseries, landscapers, and gardeners alike. The virus causes the plants to become undesirable and will eventually result in the death of the plant, which affects all segments of the rose industry as well as rosarians and home gardeners. The symptoms of disease on ornamental roses are a yellow mosaic pattern appearing on leaves, increased thorniness, abnormally shaped foliage and early production of lateral buds that make up the witches’ broom. This publication is intended for rose producers and serious rose gardeners interested in technical details of this virus and a mite that transmits it.

Carpenter bees can be a serious pest on outdoor structures made of wood, such as patios, decks, siding of homes, sheds, furniture, etc. The large carpenter bee is the most common species found in Georgia. While these bees are pollinators, mated females bore tunnels into wooden structures to raise their larvae. This tunneling causes substantial damage to wood, and sometimes even compromises the integrity of the structures they affect.

The Japanese beetle, as the name suggests, is native to Japan and was introduced to the U.S. through the transport of plant material. It is a highly devastating pest, attacking a variety of landscape and garden plants, fruit trees, field crops and turf. This circular provides an overview of Japanese beetles in the nursery and landscape, covering the biology, damage, monitoring, and management of this pest.

Thrips are tiny, cigar-shaped insects, with about 5000 known species, many of which cause damage to cultivated plants by feeding or spreading plant diseases. It is usually difficult to identify thrips species. Although they are winged, thrips are generally weak fliers, but they can be dispersed by wind and the transport of infested plant material. Some of the common thrips affecting landscape and nursery plants are described here.

Crop water requirements are not static during the growing season. They vary with crop growth stages and environmental conditions. Advanced irrigation scheduling tools use data collected from or near the field where crops are growing to provide timely information on how much water crops need and when they need it, and generally result in optimizing irrigation water use.

Monarda, commonly known as beebalm, is a North American perennial naturally found in woodlands, meadows, and floodplains. Aside from its aesthetics, beebalm offers environmental benefits, as its flowers, seeds, and shoots provide forage and habitat for many species of wildlife, including insects and birds. This publication covers the results of performance trials for 10 popular Monarda plants in the montane and piedmont (i.e., northern) Georgia regions.
