Spoiled pear harvest (4)
I believe the answer is:
reap
'harvest' is the definition.
('reap' can be a synonym of 'harvest')
'spoiled pear' is the wordplay.
'spoiled' indicates an anagram.
'pear' is an anagram of 'REAP'.
(Other definitions for reap that I've seen before include "'As you sow, so shall you . . . .'" , "Cut or gather (a harvest)" , "Harvest, garner" , "Gather 23dn" , "Cut and gather (crop)" .)
