Well, okay, a plant that could conceal illegal immigrants, the Patrol fears. The plant in question is Carrizo cane, an invasive weed that grows in dense thickets along the border. The Feds' plan (which, predictably, has drawn some Agent Orange comparisons) was to spray the cane with the herbicide Imazapyr, but not everyone is thrilled about that:
A lawsuit accused the Department of Homeland Security of violating the National Environmental Policy Act regarding the now-delayed U.S. Border Patrol plans to conduct aerial spraying of an herbicide on carrizo (kah-DEE'-zoh) cane near the Rio Grande.
Residents of two Laredo neighborhoods on Tuesday sued DHS in a lawsuit which alleged the public wasn't sufficiently notified about the spraying program, the Laredo Morning Times reported in a story for Wednesday's editions.
