'Something isn't right' in Mont. wheat fields

摘要

BIG SANDY, Mont. - Lochiel Edwards walked through ankle-high rows of wheat on his farm here on a late spring morning and spotted signs of a crop under siege: leaves with curling brown edges, and wasplike black flies zipping around his feet. It's a hint of what could confront growers if this part of Montana becomes drier and hotter during peak growing months, as climate scientists predict. "You can see the leaves are starting to roll up," Edwards said, tearing one off for a closer look. "I consider this a real problem. I'm losing yield already."
