Climate change means new and stronger weeds. In this video, University of Wisconsin-Extension weed specialist Mark Renz shows how climate change will turn some of our existing weeds such as Canada thistle into super weeds. Plus, a look at some new weed threats from the south.

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 backyard exhibition chickens in Utah County, Utah. This is the first case of virulent Newcastle disease in Utah. This case is believed to be connected to the current outbreak of virulent Newcastle disease in California, as three of the birds at the premises were recently moved to Utah from Los Angeles County, California. Since May 2018, 299 cases of Newcastle disease have been confirmed in Southern California, primarily in backyard exhibition birds.

Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products.
