Controlled and assessed to contain wrong glue (9)
I believe the answer is:
regulated
'controlled' is the definition.
(similar in meaning)
'assessed to contain wrong glue' is the wordplay.
'assessed' becomes 'rated' (rating is a kind of assessing).
'to contain' means one lot of letters goes inside another.
'wrong' is an anagram indicator.
'glue' anagrammed gives 'egul'.
'rated' going around 'egul' is 'REGULATED'.
'and' is the link.
(Other definitions for regulated that I've seen before include "Controlled - adjusted" , "As ordered" , "checked up on" , "Adjusted, or put under rule" .)
