Dusting is best, followed by syrup and extenders, IMO, anyhow.
Someone is going to say that TM dies fast in syrup. True, but it
works anyhow -- assuming the bees take it fairly quickly.  I don't
know why.
 
Your choice of methods depends whether you are seeing a bit of AFB
or not.  If so, dusting often will clean it up in a good hive at the
right time of year. Dusting will even deal with some scale -- in the
hands of an expert. But don't try this at home kids.  Not unless you
are sure you know what you are doing.
 
Extender patties are good to prevent AFB.
 
All methods are good and all require some powers of judgement and
observation to work well.
