toxicity of the individual metabolites or hydrolysis products.
I'll get some papers to you for your review. One states: " Other evidence
supporting the idea that N-monomethylformamidines (e.g., formed from
amitraz) are the actual toxicants for ticks." That has long made me wonder
just how important the amitraz degradates are, as far as toxicity to varroa.
