US re-registration for ammonium thiosulfate:

The US EPA has determined that the turf herbicide, ammonium thiosulfate, is eligible for re-registration subject to certain label changes. Applications must be limited to 1.7 lbs ai/1,000 sq ft (0.8 kg ai/93 m2) and use should not be permitted on residential turf. Labels must also reflect personal protective equipment requirements. Ammonium thiosulfate is registered as a herbicide and as an inert ingredient in other pesticides. Annual usage as a herbicide amounts to less than 6,500 lbs (2.9 tonnes). This amount is vastly exceeded by the use of ammonium thiosulfate as a fertiliser, the EPA notes.
