Ways to tell them apart:
Think of thrash as a term for wild, erratic movement, much like thrashing about in anger or pain.
On the other hand, thresh is more orderly, as it refers to removing seeds from plants, which is a specific, purposeful action.
Thrash often involves energetic and uncontrolled movements, which is quite different from the methodical and systematic action implied by thresh.
You might imagine thrash as the chaotic movement of thrashing a guitar during a rock concert.
Conversely, thresh can be visualized as the gentle beating on the wheat to separate the grain.
