2009 Annual Report 1a.Objectives (from AD-416) Facilitate an area-wide shift from pre-plant shank MB/Pic injection to effective alternative systems for control of key diseases and weeds by California cut flower and ornamental bulb producers. 1b.Approach (from AD-416) Demonstrate alternative fumigation systems at on-farm trials and greenhouses to facilitate the implementation of alternative pest management strategies by the California cut flower and ornamental bulb industry, and to establish an outreach and educational program on alternative pest management practices that decreases the methyl bromide dependency of the cut flower industry, minimizes fumigant rates and emissions, while maintaining or increasing agricultural productivity and/or economical viability.Documents SCA with UC-Davis. Formerly 5302-13220-003-21S (2/08). 3.Progress Report Drip demonstration and solarization trial were conducted with Greenhouse-grown Freesia in the fall of 2008, at All Season’s Flowers in Nipomo. Weed & stand counts were evaluated, and soil pathogen analysis were conducted. Biological Pesticides trial with field-grown Calla Lilies was started in 2008 and will continue until the fall of 2009 with Golden State Bulb Growers, Moss Landing. Drip demonstration and solarization trial with greenhouse-grown snapdragons was started in the fall of 2008 with Skyline Flowers in Oxnard. Weed & stand counts were evaluated, and soil pathogen analysis were conducted. Drip demonstration and plastic mulch trial with field-grown Ranunculus was started in the fall 2008 and harvested summer of 2009 with Mellano & Co. in Carlsbad Weed & stand counts were evaluated, and soil pathogen analysis were conducted. Yield of flowers and bulbs were determined. Data show that reduced water rates of alternative chemicals are efficacious when using improved plastic mulches with reduced permibility. The project is monitored by regular conference calls between ARS and the University investigator on the project, and also site visits by ARS.
