2013 Evaluation of Non-Irrigated Mid- to Full-Season Maturing Cotton Varieties in Jay, Florida
No full textThis report includes a summary of the 2013 mid- to full-season cotton Official Variety Trial in Jay, Florida. It shows the performance of 16 cotton varieties. This data represents only one year and one location, and readers are cautioned that test results should be considered over several locations and years before final conclusions are valid. This 5-page fact sheet was written by Darcy E. P. Telenko and Michael Donahoe, and published by the UF Department of Agronomy, January 2014
2013 Evaluation of In-Furrow and Foliar Fungicides for Disease Control in Peanut in Jay, Florida
No full textThis 10-page fact sheet summarizes the 2013 in-furrow and foliar fungicide programs for control of early and late leaf spot and white mold (southern stem rot) of peanut in Jay, Florida. It shows the effectiveness of 13 fungicide programs for disease control, as compared to no treatment. This data represents only one year and one location, and readers are cautioned that test results should be considered over several locations and years before final conclusions are valid. Written by Darcy E. P. Telenko, John Atkins, and Nick Dufault, and published by the UF Department of Plant Pathology, January 2014
Erect and Prostrate Spurge Biology and Management in Turf
No full textErect and prostrate spurges are erect or upright annuals with branched stems. Leaves are opposite and not equal. Stems produce “milky sap.” A large number of spurge species occur in Florida. Reproduction occurs via seed. This 2-page fact sheet was written by J. Bryan Unruh, Darcy E. P. Telenko, Barry J. Brecke, and Ramon Leon, and published by the UF Department of Environmental Horticulture, December 2013.

Old World Diamond-Flower Biology and Management in Turf
No full textOld world diamond-flower is a smooth, spreading summer annual. It has branched stems with opposite, narrow leaves. Flowers are white, usually with two or more on long stalks extending from the tip of a common long stalk. Flowers occur from midsummer until frost. Reproduction occurs by seed. Found in moist areas, especially areas that have been disturbed. This 2-page fact sheet was written by Darcy E. P. Telenko, Barry J. Brecke, Ramon Leon, and J. Bryan Unruh, and published by the UF Department of Environmental Horticulture, December 2013.

Spreading Dayflower Biology and Management in Turf
No full textSpreading dayflower (Commelina diffusa) is a succulent annual that produces freely branched smooth stems. Leaves are broadly lance-shaped with closed sheaths. Sheaths are short with a few soft hairs on the upper margin. Flowers have three blue petals in a leaf-like structure open on the margins. Reproduction occurs via seed and stem fragments. This 2-page fact sheet was written by J. Bryan Unruh, Darcy E. P. Telenko, Barry J. Brecke, and Ramon Leon, and published by the UF Department of Environmental Horticulture, December 2013
Black Medic Biology and Management in Turf
No full textBlack medic (Medicago lupulina) is a dark green annual with spreading, prostrate growth. Leaves are alternate with three leaflets on square stems. Leaflets are obovate to elliptic, toothed near the tip, and have a small spur on the tip. Bright yellow flowers are produced in tight, compressed clusters at leaf axils. Reproduction occurs via seed in tightly coiled black seed pods. This 2-page fact sheet was written by Barry J. Brecke, Ramon Leon, J. Bryan Unruh, and Darcy E. P. Telenko, and published by the UF Department of Environmental Horticulture, December 2013
Violet Biology and Management in Turf
No full textViolets (Viola spp.) are diverse winter annuals and perennials. Perennials form rhizomes or long stolons. Many have heart-shaped leaves on long petioles and have a rosette growth habit. Some have linear leaves and others have palmate leaves. Flowers are generally purple, but can be white, pink or yellow. They reproduce by seed or, when produced, rhizomes. This 2-page fact sheet was written by Darcy E. P. Telenko, Barry J. Brecke, Ramon Leon, and J. Bryan Unruh, and published by the UF Department of Environmental Horticulture, December 2013.

Efficacy of Biocontrol Agents Coniothyrium minitans and Bacillus amyloliquefaciens for Managing Sclerotinia sclerotiorum in Indiana Soybean
No full textSclerotinia sclerotiorum is a soilborne pathogen of soybean that causes Sclerotinia stem rot, also called white mold. Sclerotinia stem rot can cause significant yield losses under cool and wet environmental conditions. Two biofungicides, Coniothyrium minitans and Bacillus amyloliquefaciens, are currently available and labeled to limit or suppress S. sclerotiorum in soybean. These biofungicides can be applied in place of synthetic foliar fungicides to provide an alternative mode of action for the control of Sclerotinia stem rot. However, limited information is available regarding the efficacy of C. minitans and B. amyloliquefaciens as biocontrol agents of S. sclerotiorum in soybean. To assess the effectiveness of C. minitans and B. amyloliquefaciens as biocontrol agents of S. sclerotiorum, dual culture and soil plate assays were conducted, along with experiments in the growth chamber and field. Degradation of sclerotia following treatment with C. minitans in the soil plate assay confirmed that the primary mode of action is mycoparasitism. In the growth chamber, B. amyloliquefaciens at 14.03 liters/ha applied using the dip method significantly reduced Sclerotinia stem rot lesion length over the nontreated control and resulted in the lowest lesion area under the disease progress curve. When B. amyloliquefaciens and C. minitans were applied in the field, no differences were observed between treatments for soybean moisture, test weight, or yield in Indiana.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
