Shoot the rotten prigs! (5)

I believe the answer is:

sprig

'shoot' is the definition.
(thesaurus)

'the rotten prigs' is the wordplay.
'the rotten' is an anagram indicator.
'prigs' is an anagram of 'SPRIG'.

(Other definitions for sprig that I've seen before include "Spray or twig" , "Spray - youngster" , "Small stem taken from a bush or plant" , "Young person" , "Younger member of family" .)

I've seen this clue in the Evening Standard.
