Palmer amaranth (Amaranthus palmeri), an aggressive pigweed species similar in appearance to waterhemp, has been positively identified for the first time in North Dakota in McIntosh County. Palmer amaranth is native to the southwestern U.S. but was accidentally introduced to other areas and has devastated crops in the South and Midwest. It had not been identified in North Dakota until now. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on Palmer amaranth and other noxious and invasive weeds is available here. To report a suspect plant, contact the North Dakota Department of Agriculture at 701-328-2250 or North Dakota State University Extension at 701-231-8157 or 701-857-7677.

The Massachusetts Department of Agricultural Resources (MDAR) announced today that a single dead specimen of the invasive pest known as spotted lanternfly (Lycorma delicatula) was reported and confirmed at a private residence in Boston. As a result, MDAR is urging the public to check for signs of spotted lanternfly adults in any potted plants that they may have received over the holiday season and to report any potential sightings of this pest on MDAR's online reporting form by taking photographs and collecting a specimen if possible. Residents should look for large, gray insects, about one inch long, with black spots and red underwings.

Palmer amaranth (Amaranthus palmeri) and houndstongue (Cynoglossum officinale L.) have been added to the state noxious weed list. Palmer amaranth is an aggressive pigweed species similar in appearance to waterhemp and was first found in the state last year. It has now been found in five counties. Houndstongue, which does not spread aggressively like Palmer amaranth, has been found in North Dakota since at least 1911 but infestations have tripled since 2008. It is now found in at least 25 counties. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on these and other noxious and invasive weeds is available at https://www.nd.gov/ndda/plant-industries/noxious-weeds.

The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a small flock of pet chickens in Coconino County, Arizona. This is the first case of virulent Newcastle disease in Arizona. This case is believed to be connected to the current outbreak of virulent Newcastle disease in California, as tests show the virus is almost identical to the virus causing disease in California. Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products. In addition to practicing good biosecurity, all bird owners should report sick birds or unusual bird deaths to their veterinarian or to State veterinary officials. Additional information on biosecurity for all poultry flocks can be found at www.aphis.usda.gov/animalhealth/defendtheflock.
