Hi Dick & all

   In Southern Ontario we get a heavy nectar flow in July till early  
Aug.  August is a nectar dearth here until almost mid September, then  
the goldenrod flow starts(early goldenrod never seems to provide much  
nectar) and goes for several weeks and is usually almost as strong as  
the July flow(nothing last year).  A well respected researcher(I  
won't identify the speaker without permission) told me, at the NY/Ont  
joint meetings several years ago, that August was the best time to  
use formic as the temperatures are high.  She said to remove the  
honey supers then treat with formic for as long as you can, then  
replace the supers when the nectar flow starts.  I do treat this way  
but only if my drop tests indicate high mite levels.
