Good Agricultural Practices For Food Safety Of Fresh Produce, Laurie Hodges

Department of Agronomy and Horticulture: Faculty Publications

What are the guiding principles of food safety for fresh produce?

• Once contaminated, removing or killing pathogens on produce is very difficult.

• Preventing microbial contamination at all steps, from production to distribution, is strongly favored over treatments to eliminate contamination that may have occurred.

• Document the implementation of prevention programs, and educate workers at all levels of the agricultural and packing environments on food safety.

Key Signatures of a Credible Food Safety Program

The following is a condensed checklist of practices and conditions that reduce the potential for fresh produce to be exposed to pathogenic microbes. Review …

Solutions To Soil Problems: Iii. Drainage, Michael Johnson, Rich Koenig

All Current Publications

Drainage is a common problem throughout Utah. Complex patterns of soil development, transport and deposition have resulted in excessively drained soils that are coarse-textured (sandy or rocky), and poorly drained soils that are fine-textured (silt and clay-dominated). Excessively drained are more common in higher elevation and bench areas.

Establishing Buffalograss In Fine Fescue Turfgrass On The Central Coast Of California, Brittani Jean Axtell

Master's Theses

Buffalograss [Buchloe dactyloides (Nutt.) Engelm.] is a warm season, perennial grass native to the Great Plains from southern Canada to Mexico (Beetle, 1950). This newly developed, low input, turf-type grass is recommended for use on low maintenance sites (Falkenberg-Borland and Butler, 1982; Pozarnsky, 1983; Wu and Harivandi, 1989; Shearman et al., 2005). Recently, the use of buffalograss as a turfgrass has increased due to its drought tolerance, low nutrient requirements, and low growing height (Harivandi and Wu, 1995; Frank et al., 2004). It is an excellent choice in California where water use is limited. Unsightly winter dormancy of buffalograss …

Establishment And Management Practices Of Two New Warm-Season Turfgrasses In The Southern Transition Zone, John Stiglbauer

All Theses

Seashore paspalum (Paspalum vaginatum O. Swartz) is a turfgrass that has become increasingly popular in southern coastal regions of the US because of its ability to tolerate salt stress. Another reason that this turfgrass is increasing in popularity is its aesthetically appealing striping ability. Seashore paspalum could also be beneficial in areas where potable water cannot be used for irrigation. Information on this turfgrass is limited in literature, particularly on the topics of establishment, scalping, and growing this turfgrass on inland sites in the transition zone. A field experiment was conducted in Clemson, SC from May 2007 and 2008 to …

Refinement Of Innovative Watermelon Grafting Methods With Appropriate Choice Of Developmental Stage, Rootstock Type, And Root Treatment To Increase Grafting Success, Frederic Memmott

All Theses

ABSTRACT
Watermelon grafting methods used in Europe and Asia vary, but are based on efficiency, skill and needs. China mainly practices the whole insertion grafting method, whereas, Europe and Japan employ the one cotyledon (splice/slant–cut) grafting method. These methods are not suitable for grafting production in the U.S. due to the labor intensive and high labor cost necessary to successfully produce grafted transplants. This thesis introduced a modified grafting technique called the “Cotyledon Devoid Method” and in three experiments determined; 1) the rootstock leaf number stage (RLNS) at which the greatest grafting success is achieved; 2) the relationship between total …

Biology And Parasitism Rates Of Pteromalus Nr. Myopitae (Hymenoptera: Pteromalidae), A Newly Discovered Parasitoid Of Olive Fruit Fly Bactrocera Oleae (Diptera: Tephritidae) In Coastal California, Therese Kapaun, Hannah Nadel, David H. Headrick, Larisa Vredevoe

Horticulture and Crop Science

An undescribed wasp, Pteromalus nr. myopitae (Hymenoptera: Pteromalidae) opportunistically parasitizes the olive fruit fly Bactrocera oleae (Rossi) (Diptera: Tephritidae), an introduced pest of olives in California. The native or typical host of P. nr. myopitae is unknown. We demonstrate that P. nr. myopitae is a solitary, ectoparasitic, idiobiont parasitoid of the third instar host inside fruit, and pupation occurs in the host tunnel. Reproduction of P. nr. myopitae on B. oleae in olives in the laboratory and in field cages generally failed. Host-feeding was not observed, and adults fed honey and water lived longer than those provided with water alone. …

Shrub Selection For Utah Landscapes, Taun Beddes, Jaydee Gunnell, Heidi Kratsch, Rick Hefelbower

CWEL Extension Fact Sheets

Urban and suburban landscapes present special challenges concerning shrub selection in Utah. Due to our distinctive climate, shrubs must be able to withstand intense sunlight, low relative humidity, drying winds, and limited seasonal precipitation. Additionally, landscapes may also have shady locations and areas of high moisture that create unique situations. This means that ideally before purchasing shrubs, a person should research suitable species adapted to the specific location where they will be planted. Even with the unique conditions that challenge shrub species, many still perform well and should be used more often in the landscape. They soften architectural structures, provide …

An Enhanced Method For Sequence Walking And Paralog Mining: Topo® Vector-Ligation Pcr, Benjamin B. Orcheski, Thomas M. Davis

Biological Sciences

Background

Although technological advances allow for the economical acquisition of whole genome sequences, many organisms' genomes remain unsequenced, and fully sequenced genomes may contain gaps. Researchers reliant upon partial genomic or heterologous sequence information require methods for obtaining unknown sequences from loci of interest. Various PCR based techniques are available for sequence walking - i.e., the acquisition of unknown DNA sequence adjacent to known sequence. Many such methods require rigid, elaborate protocols and/or impose narrowly confined options in the choice of restriction enzymes for necessary genomic digests. We describe a new method, TOPO^® Vector-Ligation PCR (or TVL-PCR) that innovatively …
