PPFS-OR-W-17: Leaf Scorch and Winter Drying of Woody Plants

Rick Durham, Cheryl Kaiser, Nicole Ward Gauthier | Jun. 1, 2013 (New)

Leaf scorch symptoms can develop whenever water needed for growth and health of plant foliage is insufficient. While symptoms are often due to unfavorable environmental conditions, leaf scorch can also result from an infectious disease. Symptoms, possible causes, and management of leaf scorch are discussed below.

CCD-CP-39: Red and White Clover

Kenny Burdine, Cheryl Kaiser | May. 28, 2013 (Minor Revision)

Red and white (ladino) clovers are high quality forage legumes with excellent feed value and animal palatability. Red clover (Trifolium pretense), a tall-growing and short-lived perennial, is used for hay, pasture, silage, green chop, soil improvement, and wildlife habitats. While white clover (Trifolium repens), a low-growing perennial, is best suited for grazing, it can also be used for soil improvement and reclaiming disturbed land.

ID-133: Vegetable Cultivars for Kentucky Gardens, 2013

Tim Coolong, Rick Durham, Terry Jones, Kenny Seebold, John Strang, Shawn Wright | May. 6, 2013 (Major Revision)

Gardening makes sense! Growing your own vegetables makes you feel self-sufficient and provides fresh, healthful food. Your surplus crop can be frozen, canned, or stored in cool, dry locations. To assure gardening success, start by selecting suitable vegetable cultivars. Planting resistant or tolerant varieties is one of the most effective ways for the home gardener to avoid destructive vegetable diseases.

PPFS-AG-S-19: Soybean Foliar Spots and Blights

Don Hershman | May. 1, 2013 (Minor Revision)

Soybean foliage is susceptible to a number of fungal and bacterial pathogens. These pathogens cause leaf spots and blights and are generally common in Kentucky; however, few fields in any given year are seriously damaged by foliar diseases. Crop rotation and weather that is unfavorable to disease typically keeps foliar diseases at low levels. Occasionally an extended period of wet and humid weather in July to early August will result in significant amounts of foliar disease and yields may be seriously affected. However, this scenario is relatively uncommon in Kentucky.

CCD-CP-46: Switchgrass for Bioenergy

Greg Halich, Cheryl Kaiser | May. 1, 2013 (Minor Revision)

Switchgrass (Panicum virgatum) is a tall-growing, warm-season, perennial bunchgrass native to portions of Kentucky. Once a major component of the Midwestern prairies, switchgrass stands have dwindled as natural grasslands have given way to expanding farms and developments.

CCD-CP-23: Broomcorn

Matthew Ernst, Cheryl Kaiser | Apr. 18, 2013 (Minor Revision)

Broomcorn (Sorghum vulgare) is not actually corn, but is instead related to the sorghums used for grain and syrup (Sorghum bicolor). Broomcorn has a coarse, fibrous seed head that has been used to make various types of brooms and brushes for several hundred years. While there are still artisans creating these natural brooms today, this crop is now more commonly used to make decorative items, such as wreaths, swags, floral arrangements, baskets, and autumn displays. It takes about 60 sprays (heads) to make a broom, but wreaths and dried arrangements require only a few plants. Broomcorn is available in natural colors, as well as purple and various fall colors.

CCD-CP-44: Sweet Sorghum for Biofuel

Matthew Ernst, Cheryl Kaiser | Apr. 18, 2013 (New)

Sweet sorghum (Sorghum bicolor) is primarily grown in Kentucky for its syrup. However, this crop may someday have another use in the Commonwealth—as a bioenergy crop. From 2007 to 2009, University of Kentucky researchers examined the feasibility of ethanol production from sweet sorghum. They concluded that "overall sweet sorghum would appear to be a very feasible crop for ethanol production in Kentucky." Additional states, along with several other countries, have also been actively conducting research on sweet sorghum for biofuel and with promising results.

CCD-CP-45: Sweet Sorghum for Syrup

Matthew Ernst, Cheryl Kaiser | Apr. 2, 2013 (Minor Revision)

Sweet sorghum (Sorghum bicolor) is primarily grown for the sweet juice that is extracted from the plant's stalks. Stalks are crushed and the extracted juice is cooked down to a thick, sticky syrup. The syrup is sometimes incorrectly referred to as sorghum molasses.
