Husk of rice, lentils etc cause aversion (7)

I believe the answer is:

repulse

I'm a little stuck... Click here to teach me more about this clue!

'cause aversion' is the definition.
(I've seen this before)

'husk of rice lentils etc' is the wordplay.
'husk of rice' becomes 're' (I can't explain this - if you can you should believe this answer much more).
'lentils etc' becomes 'pulse' (I've seen this before).
're'+'pulse'='REPULSE'

Can you help me to learn more?

(Other definitions for repulse that I've seen before include "Ward off" , "Send back" , "Beat off -- rebuff" , "Rebuff, drive back" , "Drive back or reject" .)

I've seen this clue in The Telegraph.
