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

Adam Leonberger, Nicole Ward 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-6: Flowering Dogwood Diseases

Sarah Stolz, Nicole Ward 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.

CCD-CP-100: Heirloom Vegetables

Matthew Ernst, Cheryl Kaiser | Jul. 17, 2017 (Minor Revision)

Heirloom vegetables are vintage varieties that have been preserved by passing seed down from generation to generation. These varieties are generally 50 to 100 years old, although many are much older. All heirlooms are open-pollinated and usually breed true-to-type. Heirlooms were often selected for flavor potential and eating quality before vegetable breeding emphasized hybrid varieties bred for uniformity in size, shape and ripening, as well as for durability in shipping

CCD-CP-71: Garden Mums

Matthew Ernst, Cheryl Kaiser | Jul. 13, 2017 (Minor Revision)

The garden mum (Chrysanthemum spp.) is a popular herbaceous perennial flowering plant that is commonly grown for fall sales. While also referred to as 'hardy mums,' their actual hardiness outdoors (that is, their ability to survive the winter) can vary by cultivar, time of planting, and environmental conditions. Garden mums are generally container-grown in Kentucky, either in a greenhouse or outdoors in connection with a greenhouse business; there is also some field production in the state.

CCD-CP-60: High Tunnel Leafy Greens and Herbs

Matthew Ernst, Cheryl Kaiser | Jul. 11, 2017 (Minor Revision)

High tunnels and other season extension techniques allow producers to extend the time period over which cash flows are generated from produce crops. High tunnel production is expanding to supply the increasing demand for locally grown produce, as well as policy and grant programs favoring high tunnel production. High tunnel production of leafy greens and herbs can also enable producers to market products at higher prices, before the start of a traditional local season. High tunnel leafy greens and herbs are typically added by producers already selling through direct markets: farmers markets, CSAs (community supported agriculture programs), and direct to local restaurants and groceries.

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

Julie Beale, Walt Reichert, Nicole Ward 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.

CCD-CP-63: Hydroponic Lettuce

Matthew Ernst, Cheryl Kaiser | Jun. 30, 2017 (Minor Revision)

Lettuce (Lactuca sativa) is one of the most commonly grown hydroponic vegetables. Hydroponics is a method of growing plants without soil. Plants may be grown in a nutrient solution only (liquid culture) or they may be supported by an inert medium (aggregate culture). In both systems all of the plants' nutritional needs are supplied through the irrigation water.

PPA-47: Genetically Engineered Crops: Emerging Opportunities

Paul Vincelli | Jun. 28, 2017 (Minor Revision)

In certain biotech crops, their genetic material (DNA) has been purposefully manipulated in the laboratory. These genetically engineered crops are often called "GMOs," an acronym for "genetically modified organisms." These GMOs are the focus of this publication.

CCD-SP-8: Propagation Nursery

Matthew Ernst, Cheryl Kaiser | Jun. 5, 2017 (Minor Revision)

Propagation nurseries produce pre-finished plant material (liners), such as ornamental trees, shrubs, and grasses, fruit trees, and annual and perennial flowers. Plants are propagated either by seed or by vegetative means, such as by cuttings, grafting, or tissue culture. Some nurseries specialize in growing and selling pre-finished plants to other growers, making propagation their sole business. However, some wholesale nursery operations have their own propagation areas where plants are produced for in-house use.

CCD-CP-103: Leafy Greens

Matthew Ernst, Cheryl Kaiser | May. 3, 2017 (Minor Revision)

"Leafy greens" or "greens" are broad terms used for a number of vegetable crops with edible leaves. Plants in this group belong to several unrelated taxonomic plant families that includes Brassicaceae, Chenopodiaceae, and Asteraceae. Greens are cool-season crops that are planted in early spring or late summer/fall in Kentucky. High tunnels and similar structures can be used to extend the season into winter; however, extreme summer temperatures make year-round production in Kentucky a challenge.
