PR-757: 2018 Fruit and Vegetable Research Report

Doug Archbold, Ric Bessin, Krista Jacobsen, Emily Pfeufer, Rachel Rudolph, John Snyder, John Strang, Nicole Gauthier, Shawn Wright | Dec. 13, 2018 (New)

Fruit and vegetable production continues to show sustained growth in Kentucky. As the industry grows around a diverse collec-tion of marketing tactics (wholesale, farmers markets, CSAs, and direct to restaurants) as well as various production systems, there continues to be a need for applied practical information to support the industry.

ID-251: An IPM Scouting Guide for Common Problems of Brambles in Kentucky

Daniel Becker, Ric Bessin, Cheryl Kaiser, Matthew Springer, John Strang, Nicole Gauthier, Shawn Wright | Sep. 13, 2018 (New)

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky blackberry and raspberry plantings.

PPFS-GEN-16: Southern Blight

Carl Bradley, Emily Pfeufer, Nicole Gauthier | Aug. 1, 2018 (New)

Southern blight affects hundreds of different plants, including vegetables, field crops, ornamentals, and fruit. This disease is also known as southern stem blight, basal stem rot, Sclerotium blight, crown rot, and white mold (not to be confused with Sclerotinia white mold). Depending on host plant, production system, and environmental conditions, the severity of this disease can vary from a minor problem on isolated plants to extensive damage causing significant crop losses.

PPFS-OR-W-20: Boxwood Blight

Jamie Dockery, Nicole Gauthier | Aug. 1, 2018 (Major Revision)

Boxwood blight is a disease of boxwood (Buxus spp.), causing rapid defoliation and plant dieback. The fungal disease is particularly devastating to American boxwood cultivars, which can defoliate within a week and die within one growing season. Plants are eventually weakened by repeated defoliation and dieback, and resulting plant stress and consequent colonization by secondary invaders result in plant death.

PPFS-FR-S-3: Blackberry Rosette (Double Blossom)

Michele Stanton, Nicole Gauthier | Dec. 1, 2017 (Major Revision)

Rosette disease, caused by the fungus Cercosporella rubi, is a serious and destructive disease of blackberries in most parts of Kentucky. In some locations, growers have been forced out of growing blackberries because of rosette disease.

PPFS-FR-S-17: Cane Diseases of Brambles

Daniel Becker, Nicole Gauthier | Nov. 1, 2017 (Major Revision)

Anthracnose can cause severe damage to blackberries, purple and black raspberries, and to a much lesser extent, red raspberries in Kentucky. When left unchecked, anthracnose can significantly reduce overall yields, as well as limit the longevity of bramble plantings. Disease also causes loss of winter hardiness.

PPFS-OR-W-6: Flowering Dogwood Diseases

Sarah Stolz, Nicole Gauthier | Aug. 1, 2017 (Major Revision)

The flowering dogwood is one of the most popular ornamental trees in Kentucky landscapes. Different cultivars, as well as different species and hybrids, offer a variety of flower and plant characteristics. Unfortunately, some common diseases can threaten the health of dogwood in both residential and commercial settings.

PPFS-OR-W-26: Volutella Blight of Boxwood

Adam Leonberger, Nicole Gauthier | Aug. 1, 2017 (New)

Volutella blight (also called Pseudonectria canker) is the most common disease of boxwood in Kentucky landscapes and nurseries. This disease is caused by an opportunistic fungal pathogen that attacks leaves and stems of damaged or stressed plants. Winter injury, poor vigor, and stem wounds increase risk for Volutella blight. All species and cultivars of boxwood are susceptible.

PPFS-OR-W-25: Dothistroma Needle Blight of Pine

Julie Beale, Walt Reichert, Nicole Gauthier | Jul. 1, 2017 (New)

Dothistroma needle blight disease afflicts some of the pine species commonly planted in Kentucky landscapes, resulting in needle browning and unattractive trees. Austrian pine and Mugo pine are most commonly affected. Dothistroma needle blight is infrequently observed on spruce. A closely related fungal disease called brown spot needle blight occasionally affects Scots pine or white pine, although this disease is less common in Kentucky.
