AUGUSTA, Maine — Maine lawmakers are considering a proposal to ban aerial spraying of some herbicides in forestry.Democratic Senate President Troy Jackson, of Allagash, offered the proposal, which was subject to a public hearing on Tuesday. Jackson said “aerial herbicides in the Maine woods benefits the bottom line of large landowners at the expense and well-being of the people living and working in the region.” Jackson’s proposal focuses in part on glyphosate, a widely-used herbicide that is available commercially under the trade name Roundup.
