Clifford v. Crop Production Services, Inc., 627 F.3d 268 (7th Cir. 2010)

(plaintiff, a farmer, sued for negligence concerning glyphosate damage to corn crop; trial court's grant of summary judgment to defendant affirmed; plaintiff's expert witness testimony did not support a finding that the source of the glyphosate was the defendant's custom herbicide blend, or that had the defendant exercised reasonable care, the blend wouldn't have contained glyphosate; res ipsa loquitor inapplicable; glyphosate contamination not a serious enough problem that if it was present it necessarily implied negligence).
