222 - Evaluation of Propiconazole for Control of Fusarium Wilt of Canary Island Date Palm

Principal Investigator: Donald R. Hodel, Environmental Horticulture Advisor, UC Cooperative Extension. For more project information, click here.

Fusarium wilt of the iconic Canary Island date palm (Phoenix canariensis), a popular landscape tree, is a lethal and increasingly common disease in California and elsewhere. This disease is particularly troublesome because documented treatments are unknown and replacement Canary Island date palms replanted in the same location where one died from Fusarium wilt invariably become infected. This study evaluates the effectiveness of the fungicide Propiconazole, when injected directly into leaf bases near the apical meristem, to control Fusarium wilt.

224 New Urban Trees for a New Climate

Principal Investigator: Dr. Alison M. Berry, Plant Sciences, University of California - Davis. For more project information, click here.

224 Urban Trees
The goal of this study is to evaluate the survival, growth and arboricultural characteristics of a selection of climate-ready trees in the South California Coastal climate zone. Data will be compared with similar plantings in two other climate zones, the Inland Valley (Sacramento-Stockton-Davis), and the Inland Empire (Los Angeles- San Bernardino County). By identifying tree species that perform best under stressors associated with climate change, we can help shift the palette of trees commonly planted to species that will provide the most environmental, social, and economic value in the future.


141 – Evaluation of Agriculture Chemicals, Biologicals and IPM Methods for Ornamentals

Principal Investigator: Dr. Cheryl Wilen, Integrated Pest Management Advisor, UC Cooperative Extension. For more project information, click here.

The University of California is relied upon to provide ornamental plant growers with unbiased evaluation of pest management and other projects. The objective of this project is to provide nursery growers, landscape, and turf pest management professionals, PCAs, and related industries with information on new or refined pest management methods with an emphasis on integrated pest management. Pesticides and other pest management methods or materials that have been newly developed or adapted will be evaulated for pest management in the targeted industries or end users.

The greenhouse and nursery facilities at the UC South Coast Research and Extension Center allows us to evaluate products for the IR-4 program in a controlled environment. This is adventageous because: 1) growers would not need to set aside a portion of of the growing area or worry that the test will inadvertently be moved or sold by workers, 2) the site is easily accessible to most growers in Southern California, and 3) products can be tested on a more regular basis.

206 – Biological Filtration of Greenhouse Irrigation Runoff

Principal Investigator: Dr. Loren Oki, Department of Plant Sciences, University of California – Davis. For more project information, click here.

206 Biological Filtration
This project examines biological filtration systems (BFS) that treat runoff water for reuse in the irrigation of greenhouse and nursery grown plants. A BFS system can remove pathogens and other contaminants from water yet is relatively inexpensive to install, simple to operate and easy to maintain. There are 4 objectives of this research project: 1) To optimize slow sand filtration by determining the maximum rate of filtration while still maintaining effective removal of plant pathogens; 2) to determine if a BFS system established against Phytophthora capsici can be effective in removing other Phytophthora species; 3) to determine the ability of BFS systems to remove nematodes from runoff water; and 4) to evaluate the use of existing BFS systems in California commercial settings. 

221 - Susceptibility of Myoporum to Klambothrips myopori and Identification of the Predator Complex

Principal Investigator: Dr. Tim Paine, Entomology Department, University of California - Riverside. For more project information, click here.

221 Myoporum Study
Klambothrips myopori is an invasive thrips species, which was discovered in California in 2005 feeding on the plant genus Myoporum. Since the initial discovery of K. myopori, it has spread throughout California. This research project will take a two-tiered approach that will develop management tactics for within the nursery industry, and management tactics that will benefit the general public. The research will identify the most economical varieties of Myoporum for production and use in California. The research will also analyze potential biological control agents to be utilized within the nursery industry and within the landscape.

223 - Microcalorimetry for Rapid Assessment of Specialty Crop Salinity Tolerance

Principal Investigator: Dr. Darren Haver, Director, UC ANR South Coast Research and Extension Center; Dr. Loren Oki, Department of Plant Sciences, University of California - Davis. For more project information, click here.

223 - Specialty Crops
Currently, there is limited information regarding salt tolerances for a wide range of specialty crops since testing for salt tolerances is resource and time intensive. Isothermal microcalorimetry can be used to examine total metabolic rates of plant tissue samples and to study effects of a wide variety of naturally occurring or artificially added factors, including salinity, on those rates. Our project will use this procedure to develop a novel method to rapidly (hours or days) assess the salinity tolerance of specialty crops species. The first two years will be used to develop and validate the method. During the third year we will establish experimental field demonstrations. Measurable benefits will be in pioneering a new scientific method; and by identifying and disseminating previously unreported salt tolerances for specialty crops. Expanded knowledge of salinity tolerance will improve sustainable production practices by allowing for increased use of recycled water for irrigation.
