That weed appears to be horseweed (Conyza canadensis), also known as marestail.
Key Features That Match:
  • Tall, upright growth (can reach over 6 feet)
  • Narrow, lance-shaped leaves that are arranged alternately
  • Central stem that's often unbranched until flowering
  • Often found in pastures, roadsides, and disturbed fields
Notes:
  • Horseweed can be problematic in pastures and crop fields, especially because it's resistant to some herbicides like glyphosate.
  • It typically emerges in spring or fall and can grow rapidly in warm weather.
  • Cattle generally avoid eating it due to its poor palatability.
Control Options:
  • Mowing before flowering can help reduce seed spread.
  • Herbicide application (such as 2,4-D or dicamba-based products) is most effective when the plant is still in the rosette stage.
