That weed appears to be horseweed (Conyza canadensis), also known as marestail.
Key Features That Match:

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.
