Hopper Treatment Planned for Areas in Eastern Montana

The U.S. Department of Agriculture's Animal Plant Health Inspection Service in cooperation with the BLM's Miles City Field Office will be treating grasshoppers in portions of eastern Montana.

Treatment could begin as early as June 17 and will conclude by early-mid July.

Areas currently targeted include Prairie, eastern Custer, southern Bighorn and Powder River counties; western and northwestern Garfield County and southwestern McCone County.

All chemical will be applied aerially and target areas will be treated utilizing the Reduced Agent-Area Treatment (RAATs) methodology. This method of treatment provides for the application of the insecticide in strips; with coverage of no more than 60 percent of the targeted treatment area.

The chemical of choice is Dimilin 2L –an insect growth inhibitor– which is toxic to a small array of insects but is not toxic to humans, livestock or wildlife.

Treatment of grasshoppers is authorized within BLM Wilderness Study Areas. No treatments will be allowed within 500 feet of dwellings, recreation sites, domestic bee colonies, perennial and intermittent streams, rivers, lakes and reservoirs.

The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
