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 Virginia Department of Agriculture and Consumer Services (VDACS) established a Spotted Lanternfly Quarantine for Frederick County and the city of Winchester, effective immediately. The purpose of the quarantine is to slow the spread of the spotted lanternfly to uninfested areas of the Commonwealth. Early detection is vital for the management of any newly introduced plant pest. For more information on Spotted Lanternfly in Virginia, see: Plant Industry Services (scroll to SLF section).

The spotted lanternfly was first detected in Winchester in January 2018. Subsequent surveys conducted by VDACS indicate that the pest has become established in the city of Winchester and spread into Frederick County, just north of Winchester. Prior to the January 2018 detection in Virginia, the only Spotted Lanternfly (SLF) found in the U.S. was in Pennsylvania. Populations are now established in Pennsylvania, New Jersey, Delaware and northern Virginia.
