 Abstract
Safflower lygus bug Food Use Residue IR-4 Project 12750 The Nichino product PQZ (pyrifluquinazon) was selected for prioritization at the IR4 Food Use Workshop for a residue study to address the growers needs for lygus control in safflower and sunflower production.  Three trials were conducted in California by UC researchers under the EPA guidelines for residue research.  All trials and the subsequent residue sample analysis have been completed and the data will be sent to the EPA to obtain a new registration for use in the safflower crop group.  The final report to EPA is available upon request.
Onion thrips Food Use Residue IR-4 Project 08550 The Bayer product Sivanto (flupyradifurone) was prioritized and selected for IR4 residue trials. Following EPA guidelines for residue research four residue trials were conducted in California, two with UC field researchers and two with a private contractor. The four field trials are completed, samples have been analyzed and will be summarized and submitted to the EPA for registration on Olives.  The final report to EPA is available upon request.
Beet armyworm in rice Food Use Residue IR-4 Project 12790 The FMC product Coragen (chlorantraniliprole) was prioritized and selected for IR4 residue trials. Following EPA guidelines for residue research four residue trials were conducted in California with UCD field researchers. All trials are completed, samples have been analyzed and will be summarized and submitted to the EPA for registration on rice.  The final report to EPA is available upon request.
Blueberry citrus thrips Food Use Residue IR-4 Project 12831 In response to California growers’ need for post-harvest control of citrus thrips in blueberries for export, pyrifluquinazon (Nichino’s product PQZ) was prioritized for a residue study.  All trials and the subsequent sample analysis have been completed.  The final report will be sent to the EPA for the registration to be approved for grower use.  The final report to EPA is available upon request.
Grape mealybug Integrated Solutions Grape mealybug report This project screened a number of products for efficacy as a replacement for chlorpyrifos in controlling grape vine mealybug, which is the only current option for growers.  Two trials were conducted in California.
Tomato fusarium crown rot Integrated Solutions Research ongoing Fusarium crown rot has become an increasing problem in processing tomato production in the Central Valley, reducing yields by more than a quarter.  UC Extension Plant Pathologist Cassandra Swett is conducting efficacy trials with potential products to control the fusarium.
Western flower thrips in ornamental plants Environmental Horticulture Western flower thrips report This study tested new conventional products and biopesticides on their effectiveness to control Western Flower thrips in ornamental plants.  The trials were conducted at UC Davis.
Citrus mealybug in ornamental plants Environmental Horticulture Citrus mealybug report These trials were conducted at UC Davis to search for chlorpyrifos alternatives to control citrus mealybug in ornamental plants.  Products tested included conventional chemistries and biopesticides.
