CCD-CP-33: Industrial Hemp Production

Christy Cassady, Matthew Ernst, Cheryl Kaiser | Sep. 23, 2015 (Minor Revision)

Industrial hemp (Cannabis sativa L.) is a versatile plant that can be grown for its fiber, seed, or oil. Hemp fields were once a common sight in Kentucky during the state's prominence as the leading hemp producer in the U.S. Although commercial hemp production ceased throughout North America in the late 1950s, there is currently renewed interest in growing this crop. While hemp faces significant legal obstacles due to its close relationship to the marijuana plant, there are a number of states, including Kentucky, working toward reviving the hemp industry. Section 7606 of the Agricultural Act of 2014 (the federal farm bill) authorized state departments of agriculture in states that have legalized hemp, including Kentucky, to develop pilot programs for industrial hemp research. The Kentucky Department of Agriculture has been working with universities, farmers and processors around the state since 2014 to implement pilot programs.

PPFS-OR-W-1: Tree Wounds: Invitations to Wood Decay Fungi

Bill Fountain, Traci Missun, Nicole Ward Gauthier | Sep. 1, 2015 (New)

Wood decay leads to loss of tree vigor and vitality, resulting in decline, dieback, and structural failure. Wounds play an important part in this process since they are the primary point of entry for wood decay pathogens. While other factors may also result in decline and dieback, the presence of wounds and/or outward signs of pathogens provides confirmation that wood decay is an underlying problem. Wounds and wood decay reduce the ability of trees to support themselves.

CCD-CP-67: Christmas Trees

Matthew Ernst, Cheryl Kaiser | Aug. 18, 2015 (Minor Revision)

Christmas trees can be grown on relatively small parcels of land. This enterprise can fit in well with an existing farm or nursery operation. While Christmas tree production does have a high profitability potential, it is also a long-term, risky investment requiring periods of intensive labor.

PPFS-FR-T-5: Apple Rust Diseases

Annette Meyer Heisdorffer, Nicole Ward Gauthier | Aug. 1, 2015 (New)

Cedar-apple rust is the most common and economically important rust disease occurring on apple in Kentucky. Two other rusts, cedar-hawthorn rust and cedar-quince rust, are of lesser importance on apple, but can significantly impact ornamental plants. All three diseases occur on crabapple, hawthorn, mountain ash, pear, and serviceberry.

PPFS-OR-H-10: Garden Mum Production: Diseases and Nutritional Disorders

Ray Tackett, Nicole Ward Gauthier | May. 1, 2015 (New)

Many Kentucky vegetable and greenhouse producers are beginning to include fall chrysanthemum production in their operations. Garden mums are usually planted in June and sold in September when fall color is in demand. Production can vary in size; small scale growers may produce as few as 200 plants per season. Size of the operation influences cultural practices, as well as initial investments in important practices (e.g., surface drainage, pre‐plant fungicide dips, and pre‐emergent herbicides); all of which can impact disease management.

PPFS-FR-S-19: Blueberry Root Rot

Nicole Ward Gauthier | May. 1, 2015 (New)

Blueberry is considered one of the most disease-free fruit crops in Kentucky. Many of the diseases that affect blueberry result in minor damage. However, the most common disease of blueberry, Phytophthora root rot, can cause severe dieback and often results in plant death. The causal agent of blueberry root rot is Phytophthora cinnamomi, a soilborne water mold that occurs world-wide and can infect a wide range of hosts, including woody ornamentals. Under optimal conditions, the pathogen proliferates, and disease symptoms occur.

PPFS-OR-W-22: When White Pines Turn Brown: Common Problems of White Pines in Kentucky

Julie Beale, Nicole Ward Gauthier | Apr. 1, 2015 (New)

Eastern white pine (Pinus strobus) is a popular conifer in many Kentucky landscapes, although its use may be limited to loose, well-drained, pathogen-free soil. Often, needle browning is the primary symptom that alerts homeowners and nursery growers of health problems. In Kentucky, brown needles on white pine are often caused by one of the following three conditions: white pine decline, white pine root decline (Procerum root rot), or Phytophthora root rot.

CCD-CP-51: Culinary Herbs

Matthew Ernst, Cheryl Kaiser | Apr. 1, 2015 (New)

Culinary herbs may be sold fresh, dried, and as live plants. Potential fresh herb growers should talk to upscale restaurant chefs, caterers, or to produce brokers, especially those who sell to restaurants. Kentucky restaurants surveyed in 2006 indicated they were most interested in sourcing basil, chives, cilantro, parsley, and rosemary from local growers. Other herbs of specific interest to restaurants include horseradish, oregano, sage, tarragon, and thyme.

PPA-41: Fundamental Principles of Plant Pathology for Agricultural Producers

Paul Vincelli | Mar. 9, 2015 (Major Revision)

All crop plants produced in Kentucky have the potential to become diseased under certain conditions. Diseases of crops can affect yield and/or quality of the harvested commodity, which can impact profitability and increase the risks of farming. A plant is diseased when it is affected by some agent that interferes with its normal development. Some disorders are caused by noninfectious factors, such as temperature extremes or nutrient deficiencies. However, this publication focuses on diseases caused by infectious microorganisms.
