It can also damage citrus trees, landscape plants and other crops.<\/p>\n<p class=\"wp-block-paragraph\">CDFA\u2019s Pierce\u2019s Disease Control Program, in coordination with the county agricultural commissioners and Costco, are actively responding to the situation. Early detection and rapid response are critical to preventing the pest from spreading further.<\/p>\n<p class=\"wp-block-paragraph\">The infested nursery stock came from Burchell Nursery in Fresno. Fresno County agricultural commissioner staff and CDFA personnel have been working on-site since May 19 to stop shipments, investigate the situation and determine corrective actions.<\/p>\n<p class=\"wp-block-paragraph\">State and local agriculture officials identified the issue quickly and immediately began response and containment efforts. County agricultural commissioners in affected areas are conducting inspections, responding to public reports, coordinating trapping efforts and helping ensure potentially infested plants are safely contained and disposed of.<\/p>\n<p class=\"wp-block-paragraph\">Costco has been working cooperatively with CDFA to notify customers, issue refunds and help connect purchasers with local county agricultural commissioner offices for inspection and disposal guidance.<\/p>\n<p class=\"wp-block-paragraph\">\u201cIf you purchased a grapevine from Costco in an affected county during that timeframe, contact your local <a href=\"https:\/\/www.cdfa.ca.gov\/exec\/county\/countymap\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">county agricultural commissioner\u2019s office<\/a> right away,\u201d the CDFA website urges.<\/p>\n<p class=\"wp-block-paragraph\">Affected counties are Alameda, Butte, Contra Costa, Fresno, Humboldt, Kings, Marin, Mendocino, Merced, Monterey, Napa, Placer, Sacramento, San Joaquin, San Mateo, Santa Clara, Santa Cruz, Shasta, Solano, Sonoma, Stanislaus, Tulare, Yolo and Yuba.<\/p>\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.cdfa.ca.gov\/pdcp\/gwss-costco-plants.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Get more information<\/a> from the CDFA about recommended actions and other details.<\/p>\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/ipm.ucanr.edu\/home-and-landscape\/glassy-winged-sharpshooter\/#gsc.tab=0\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Learn more<\/a> from University of California Agriculture and Natural Resources about the glassy-winged sharpshooter.<\/p>\n<p class=\"wp-block-paragraph\">Source: Citrus Pest &amp; Disease Prevention Program<\/p>\n<p>\n\tRelated\n<\/p>\n<p>Sponsored Content<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/05\/B29713265.363976730;dc_trk_aid=557520999;dc_trk_cid=192006927;ord=[timestamp];dc_lat=;dc_rdid=;tag_f.gif\" attributionsrc=\"\" border=\"0\" height=\"1\" width=\"1\" alt=\"Advertisement\"\/><\/p>\n","protected":false},"excerpt":{"rendered":"Glassy-winged sharpshooterPhoto courtesy of University of California, Riverside The California Department of Food and Agriculture (CDFA) is responding&hellip;\n","protected":false},"author":2,"featured_media":356157,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[7,127768,9,8],"class_list":["post-356156","post","type-post","status-publish","format-standard","has-post-thumbnail","category-california","tag-california","tag-california-department-of-food-and-agriculture-cdfa","tag-california-headlines","tag-california-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/356156","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=356156"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/356156\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/356157"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=356156"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=356156"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=356156"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
