Re. Mavrik/Amitraz Use in Beehives
 
    I read with some concern the communication on the use of amitraz in
    beehives and the type of formula needed.  My suggestion is NEVER use the
    product in your colonies.
 
    Based on data collected over 15 years (primarily intended to consider
    the use of amitraz to control pear psylla in pear orchards), I wrote a
    short article in 1991 on the nature of this product.  While Apistan (ie.
    fluvalinate) has a very low mammalian toxicity, amitraz is exceedingly
    toxic especially man.  Stay away from it!
 
    PS.  For anyone wishing a copy of the 91 article, please e.mail
    directly.
