The change was mentioned in a response to comments in the Buffalo Hills DNA.
The January 21 labeling amendment allows the second dose to be given in as little as seven days after the first.
The effect of the change on treated animals is not known.
Although the 2017 labeling amendment changed the interval to 90 days, the BLM continued to refer to the 2013 and 2015 registrations in planning documents issued after that date and gave two doses 30 days apart to mares captured in roundups, which constitutes unlawful use of the pesticide.
If that sounds like an allegation of wrongdoing, it is.
