This bulletin describes a recommended procedure to measure soil saturated hydraulic conductivity (Ks) with a borehole permeameter and convert this value to estimates of percolation rate for on-site wastewater treatment systems. Saturated hydraulic conductivity is a fundamental hydraulic parameter for soil water flow and it is defined as the ratio of the water velocity to the hydraulic gradient. This bulletin also provides information on a computer-based program to help calculate saturated hydraulic conductivity.

The 2021 Southeast Regional Caneberry Integrated Management Guide covers topics such as pesticide stewardship and safety, insect and disease control, pre-transplant and transplant operations, fungicide and insecticide efficacy comparisons and spray schedules, weed management, wildlife damage, and more. Recommendations are based on information from the manufacturer’s label and performance data from research and extension field tests. Because environmental conditions and grower application methods vary widely, suggested use does not imply that performance of the pesticide will always conform to the safety and pest control standards indicated by experimental data. This publication is intended for use only as a guide. Specific rates and applications methods are on the pesticide label, and these are subject to change at any time.

The “Vineyard Canopy Management Series” of Extension circulars reviews a number of canopy-management practices individually. Each circular advises how to effectively implement a canopy-management practice and why it is important to do so. The practices collectively known as “canopy management” aim to maximize canopy leaf exposure, maintain crop yield and quality, decrease disease, and improve vineyard health and sustainability. Though labor-intensive, canopy management should not be considered optional if the goal is annual production of high-quality grapes and wines.

Results from this study are preliminary, as only 2 years of data have been collected. Research over longer periods of time will be more revealing about how mechanical pruning will impact the perennial crop yield and health of the vineyard. Mechanical pruning is an option for dormant pruning ‘Carlos’ in situations where labor is unreliable and/or there is a low labor-to-acreage ratio which precludes the ability to finish pruning in the dormant period (December through March).
Concerns remain regarding the inaccuracy of mechanical pruning and the resultant amount of diseased and unproductive grapevine wood that remains in the canopy. It therefore may be a good practice to manually prune blocks of the vineyard on a recurring basis in order to reduce canopy congestion and the potential for disease buildup. Mechanical pruning may not be best practice in fresh-market muscadine cultivars, particularly those that produce bronze fruit that are less tolerant of rots and defects than purple fruit.
Mechanical pruning ‘Carlos’ and ‘Noble’ vineyards is worth consideration as these popular juice muscadine cultivars are vigorous and productive and may therefore sustain perennial health under high bud densities. Because of the preliminary nature of this report, it is recommended that mechanical, or “minimal” pruning, be trialed in vineyard blocks or sections before it is widely implemented with confidence.

The crape myrtle bark scale (CMBS) is an emerging threat to crape myrtle (Lagerstroemia spp.) in Georgia. As the name indicates, this scale pest attacks the bark of crape myrtle, the only known scale insect that infests crape myrtle bark. A native of Asia, CMBS was first confirmed in Dallas, Texas, in 2004. Since then, the pest has gradually expanded its range to the southeastern states. In Georgia, it was first confirmed in Coweta County in 2014. In 2019, CMBS were found infesting crape myrtles in an ornamental nursery in south Georgia. They can potentially spread in zones 6 to 9.

Built-financial capital refers to the constructed environment (or infrastructure) and economic resources needed to support community activities and sustain successful community development. Considering the infrastructure as well as the financial resources within a community may provide an important perspective regarding needs as well as opportunities.
