A portion of Los Angeles County has been placed under quarantine for the Oriental Fruit Fly following the detection of 14 flies in the San Fernando Valley in the North Hills area. To prevent the spread of fruit flies through homegrown fruits and vegetables, residents living in the quarantine area are urged not to move those items from their property. However, they may be consumed or processed (i.e., juiced, frozen, cooked, or ground in the garbage disposal) on the property where they were picked or disposed of by double bagging and placing in the regular trash, not green waste. Residents with questions about the project may call CDFA’s Pest Hotline at 1-800-491-1899. Additional information may be found here: www.cdfa.ca.gov/plant/off.
After 12 years of research, a parasitic wasp that controls a highly destructive fruit fly will be released by Oregon State University agricultural scientists in June. Vaughn Walton, Extension entomologist and professor in the College of Agricultural Sciences, said the U.S. Department of Agriculture has permitted release of the wasp (Ganaspis brasiliensis), a slow process that took more than 10 years from application to decision. Now that it has a permit, Walton’s lab, which is part of the OSU Agricultural Experiment Station, is raising enough wasps to make a dent in the spotted wing drosophila (SWD) population in Oregon.
New Hampshire Department of Environmental Services.
On July 1, 2019, a new law (RSA 487:43) went into effect, requiring all persons operating a motorboat that is registered in another state (other than New Hampshire) on New Hampshire public waters, to display a New Hampshire aquatic invasive species decal from the Department of Environmental Services.
This handbook is intended as a ready reference guide to the control and management tactics for the more important plant diseases in the Pacific Northwest. The specific cultural, biological, and chemical recommendations are intended to manage a specific plant disease but may not always be appropriate under all production circumstances. The synthesis of a specific management recommendation should be done by a qualified individual. For this reason, this book should be used by—and has been expressly written for—county Extension agents, consultants, field and nursery people, and chemical industry representatives. Information in this publication is in a state of constant change.
