CCD-CP-73: Ornamental Grasses

Matthew Ernst, Cheryl Kaiser | Sep. 26, 2018 (Minor Revision)

Ornamental grasses are popular for use in commercial and homeowner landscapes. Attractive foliage, showy flowers and distinctive seed heads make many annual and perennial grasses suitable for fresh and dried floral arrangements. Ornamental grasses can be added to an existing nursery operation or become the focus of a specialty nursery.

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

Daniel Becker, Ric Bessin, Cheryl Kaiser, Matthew Springer, John Strang, Nicole Ward 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.

CCD-CP-5: Elderberry

Matthew Ernst, Cheryl Kaiser | Sep. 12, 2018 (Minor Revision)

Elderberry (Sambucus nigra subsp. canadnesis) is a large shrub or small tree native to Kentucky. The small fruit has prominent seeds and are produced in large clusters. While elderberries are not normally eaten fresh due to their tartness, wild and cultivated elderberries can be processed, either alone or with other fruit.

CCD-CP-121: Summer Squash

Matthew Ernst, Cheryl Kaiser | Sep. 10, 2018 (Minor Revision)

Summer squashes (Curcurbita pepo) are warm-season cucurbits that are harvested when the fruits are immature. The most common summer squash types include yellow (crookneck and straightneck) and zucchini. Also included in the summer squash group are scallop squashes and cocozelle. Summer squashes grow on plants with a bush growth habit, rather than vining.

PPFS-AG-C-8: Diplodia Leaf Streak

Nolan Anderson, Carl Bradley, Kelsey Mehl, Kiersten Wise | Sep. 1, 2018 (New)

Diplodia leaf streak of corn is a disease that has become more prevalent in Kentucky in recent years. It is commonly observed in fields in western Kentucky and is easily confused with other corn foliar diseases. Small, round, dark brown-to-tan lesions are first observed on leaves. Dark concentric rings may be observed in the center of early lesions at the infection site on the leaf. These lesions expand lengthwise in long streaks from the infection point and form elongated elliptical lesions. In severe cases, lesions can coalesce to blight large areas of affected leaves.

CCD-CP-98: Field-grown Tomatoes

Matthew Ernst, Cheryl Kaiser | Aug. 3, 2018 (Minor Revision)

Tomato (Lycopersicon esculentum) is a warm-season crop that originated in South America. Tomatoes are one of the most popular and profitable crop alternatives in Kentucky. Growers able to provide the earliest locally grown tomatoes can often demand a premium price.

PPFS-OR-W-20: Boxwood Blight

Jamie Dockery, Nicole Ward 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-GEN-16: Southern Blight

Carl Bradley, Emily Pfeufer, Nicole Ward 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.

CCD-CP-3: Asian and European Pears

Matthew Ernst, Cheryl Kaiser | Jul. 31, 2018 (Minor Revision)

Very few European pears (Pyrus communis) are grown commercially in Kentucky, primarily due to problems with fire blight and late spring frosts. Asian pears (P. pyrifolia, synonym P. serotina), on the other hand, are more consistently productive in Kentucky in spite of these problems. Also called apple pears, Asian pears are crisp and juicy like an apple, but with the sweetness associated with pears.

CCD-CP-14: Pawpaw

Matthew Ernst, Cheryl Kaiser | Jul. 31, 2018 (Minor Revision)

Pawpaw (Asimina triloba) is a unique tree fruit native to the eastern United States. Its highly aromatic fruit has a sweet, almost tropical-like flavor. The large fruit is oblong and typically produced singly or in clusters of two to nine. Pawpaw fruit pulp can be eaten fresh or prepared in a variety of desserts. Kentucky is fortunate to have the USDA National Clonal Germplasm Repository for Asimina spp. located at Kentucky State University in Frankfort.
