CCD-CP-35: Kura Clover

Matthew Ernst, Cheryl Kaiser | Mar. 1, 2014 (Minor Revision)

Kura clover was investigated by the University of Kentucky Department of Plant and Soil Sciences for several years. Unfortunately, due to establishment difficulties, UK researchers have concluded that kura clover succeeds best further north.

PPFS-GEN-9: Submitting Plant Specimens for Disease Diagnosis

Julie Beale, Brenda Kennedy, Sara Long, Nicole Gauthier | Mar. 1, 2014 (New)

Diagnosis of plant diseases is one of the many ways that the University of Kentucky Plant Disease Diagnostic Laboratory and UK Cooperative Extension serve the citizens of Kentucky. This publication is designed to help growers collect and submit the best plant samples for an accurate diagnosis.

PPFS-GEN-11: Diagnosis of "No Disease"

Julie Beale, Brenda Kennedy, Sara Long, Nicole Gauthier | Mar. 1, 2014 (New)

Extension Agents and growers may occasionally receive diagnostic reports from the University of Kentucky Plant Disease Diagnostic Laboratory that indicate "no disease was found." One or both of the following explanations may account for the diagnosis of "No Disease."

CCD-CP-43: Sunflower for Seed

Carl Dillon, Cheryl Kaiser, Michael Vassalos | Mar. 1, 2014 (Minor Revision)

Sunflower is classified as either an oil type or a confection (non-oil) type, each with its own distinct market. Seeds from oil types are processed into vegetable oil or as meal in livestock feed. Most confection type seed is sold, with or without the hull, as snack foods. While either type can be packaged for birdseed, the confectionery type is grown in Kentucky for this purpose. Sunflowers are not recommended for oil crop production here.

CCD-CP-34: Kenaf

Matthew Ernst, Cheryl Kaiser | Feb. 18, 2014 (Minor Revision)

Kenaf (Hibiscus cannabinus) is a warm season annual row crop in the same plant family as okra and cotton (Malvaceae). Kenaf plants are capable of growing to a height of 20 feet under favorable conditions; however, heights generally average 8 to 14 feet in a growing season of 4 to 5 months. The stalks consist of two kinds of fiber: an outer fiber (bast) and an inner fiber (core). The bast is comparable to softwood tree fibers, while the core is comparable to hardwood fibers. After harvest, the plant is processed to separate these fibers for various products

PR-673: 2013 Fruit and Vegetable Research Report

Doug Archbold, Ric Bessin, Shubin Saha, Kenny Seebold, John Snyder, John Strang, Nicole Gauthier, Patsy Wilson | Jan. 8, 2014 (New)

Variety trials included in this year's publication include: cabbage, asparagus, bell peppers, blueberries, blackberries, raspberries, apples, peaches, and grapes. Additional research trials include organic management of cucumber beetles, financial comparison of organic potato integrated pest management systems, and effect of organic fertilizer materials for production of kale.

PPFS-MISC-2: Some Principles of Fungicide Resistance

Paul Vincelli | Jan. 1, 2014 (New)

Fungicides are important tools in modern crop production. Unfortunately, one of the risks of using these products is that fungi sometimes develop resistance to them. Resistance development is a concern because the products may become less effective--or even useless--for controlling resistant pathogens and pests. This is a concern for all pesticides, including fungicides, insecticides, and herbicides. This fact sheet is intended to help pesticide applicators better understand this process.

PPFS-AG-S-9: Sampling Soybean Fields for Soybean Cyst Nematode Analysis

Don Hershman | Jan. 1, 2014 (Minor Revision)

The soybean cyst nematode (Heterodera glycines, SCN) causes many millions of dollars worth of damage to Kentucky soybean fields each year. This occurs even though damage is mostly preventable and controls are inexpensive. This situation exists because a large number of soybean producers are unaware that cyst nematode is damaging their crops. In most cases soybean cyst nematode will cause significant yield reductions without producing any detectable symptoms in soybeans. When symptoms do occur, they are frequently thought to be associated with some other factor, such as soil compaction or low soil fertility.

ID-84: Iron Deficiency of Landscape Plants

Cheryl Kaiser, Edwin Ritchey, Nicole Gauthier | Oct. 16, 2013 (Major Revision)

Iron deficiency is a nutritional deficit that can occur in woody and herbaceous plants in landscapes, nurseries, greenhouses, and production fields. It is most often associated with soils that have neutral or alkaline pH (pH 7.0 or above). Plants that grow best in acidic soils are particularly vulnerable to this condition. In Kentucky, iron deficiency is most commonly observed on pin oak, willow oak, azalea, rhododendron, and blueberry, but other woody plants are also susceptible.

PPFS-GEN-5: Fruit, Orchard, and Vineyard Sanitation

David Koester, Faye Tewksbury, Nicole Gauthier | Aug. 1, 2013 (New)

Diseases can become a significant problem in commercial and home fruit plantings, resulting in premature leaf drop, fruit decay, dieback, decline, and even plant death. When diseases do occur, it is often presumed that fungicides are the most important and effective disease management tools available. However, a good sanitation program can help reduce the need for chemical controls and can improve the effectiveness of other practices for managing disease. This often-overlooked disease management tool reduces pathogen numbers and eliminates infective propagules that cause disease.
