Many third-party audits, buyers, and standard operating procedures for produce packinghouses or other food facilities require regular adenosine triphosphate (ATP) or protein swabs to verify the effectiveness of the cleaning and sanitation protocols. This video demonstrates how to collect ATP and protein swabs, how to interpret swab results, and provides advice to help determine an acceptable baseline when implementing a new swabbing program.

Fertilization is an important practice of maintaining plant health. The blueberry plant is no exception, but there are important considerations when fertilizing blueberries. The rates, timing, and type of fertilizer should be common knowledge for the grower. In this circular, how to fertilize blueberry plants is described with text, diagrams, and calculations to provide growers, Extension agents, and anyone interested with the knowledge to successfully grow blueberries, from newly established to mature plantings. This publication was written to address commercial growers’ need for a reference to avoid costly mistakes such as over-fertilization, discussing both granular and liquid fertilization.

Drip, trickle, microemitters, and subsurface irrigation systems are considered low-volume irrigation. Low-volume irrigation systems are designed to improve irrigation efficiency, delivering water to the crop accurately with minimal water loss. Irrigation efficiency can be categorized into two main concepts: water loss and uniform application. If water loss is significant, or application uniformity is poor, efficiency will be low. Generally, the most significant loss of irrigation water is from overwatering, where the water percolates below the root zone, or from runoff. With good management, losses due to leaks, system drainage, and flushing of filters and lateral lines should not exceed 1%. Low-volume systems have the opportunity to achieve efficiency, and under careful management, will minimize losses from overirrigation. However, using low-volume systems requires increased irrigation frequency and soil moisture monitoring should be used to improve water-use efficiency. This publication covers system design, system efficiencies, components, chemical applications, diseases related to irrigation, and soil moisture monitoring.

Currently, European gypsy moth is one of the top quarantine species in the United States. Thanks to the efforts of the U.S. Forest Service and other organizations, such as the Slow the Spread Foundation, the spread of European gypsy moth has slowed dramatically and has yet to become established in Georgia. However, residents and commercial landscape/nursery persons should continually monitor for the pest. This review is intended to provide an introduction to European gypsy moth for residents and green industry professionals in the Southeast. It provides information on European gypsy moth identification, life cycle, means of spread, methods of control, and what can be expected in the Southeast if/when the insect arrives and becomes established.
