Palmer amaranth (careless weed or pigweed) is a plant native to the desert southwest that has developed resistance to multiple herbicide mechanisms of action (MOAs). In multiple crops, in all major Arizona agricultural areas, Palmer amaranth resistant to glyphosate and ALS inhibitors (e.g., Staple®) can be found. A diversity of control tactics are needed to manage herbicide resistant Palmer amaranth.

External parasites, such as mites and poultry lice, are common pests on birds, especially in backyard chickens. They feed on the blood and bite skin, feathers, or scales of the bird. A heavy infestation of these pests can result in poor poultry health, reduced growth and egg production, and sometimes can even cause bird deaths. This article provides basic information on how to recognize the signs and symptoms of an infestation, and how to effectively treat infested birds.
