The 2019 Iowa State University Extension and Outreach Iowa State Fair Weed Identification Contest was held on August 9 outside the John Deere Agriculture Building. Contestants need to identify live samples of weeds of agricultural, horticultural, and natural habitats in Iowa. Youth are tasked with identifying the first 20 weeds, species that are common across the state. Those competing in the General Division identify an additional 10 weeds, which are less common species.

Weedy Amaranthus Quiz II
Blog Post
The six weedy Amaranthus species at the weed garden have grown quite a bit, but I'm not sure how much easier it is to differentiate a few of the species. The six pigweeds are Palmer, Powell's and spiny amaranth, waterhemp, and redroot and tumble pigweed (not in that order!!). The purpose of this exercise is to demonstrate how easy it would be to overlook Palmer amaranth in fields if time isn't taken to make sure exactly what Amaranthus you're dealing with. Scroll to the bottom to find the answers.

Think you know your pigweeds?
Blog Post
This year at the ISU FEEL weed garden I've established a plot with nine weedy members of the Amaranthaceae family, including six pigweeds . The pigweeds were transplanted on June 9 and pictures taken on June 11. Species include redroot pigweed, tumble pigweed, Palmer amaranth, spiny amaranth, Powell's amaranth, and waterhemp. How many can you correctly identify? If you visit FEEL this year, take time to visit the garden.
