Lawn Sweeper to Collect Nightshade Plants & Berries?

[Margali]

I have several areas in my fields that are full of silver nightshade. I noticed today that the bermuda grass has died/been grazed low while nightshade plants still stand tall. Could I cut them and collect with lawn sweeper so berries don't grow more plants?

It's wet there...could you pull them up and burn or trash? May be too much area but...

I guess you could take a run at it and see.
