Stands in seeds I put out (9)
I believe the answer is:
deputises
'stands in' is the definition.
(I've seen this before)
'seeds i put out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'seeds'+'i'+'put'='seedsiput'
'seedsiput' is an anagram of 'DEPUTISES'.
(Other definitions for deputises that I've seen before include "Stands in" , "Steps in" , "Delegates" .)
