Could anyone please post data to support this claim?
This is a substantial accusation against formic acid.
I can not.
On the contrary I run a feeding experiment this summer (february-march)
giving pollen supplement and not, putting at the same time pads of formic
acid (BioTab not Mite Away) and not.
The 300 ones with feeding and formic end the honey season with well over 16
frames with bees, while the 150 ones without feeding or varroa treatment end
up with less than 8 frames with bees. The first group have a 10% to 15%
varroa load and were given a autum treatment eith amitraz a week ago. The
first group shows in more than 20% of the hives PMS and the varroa load
average is over 40%. This group was also treated with amitraz but end march.
