In 1984 4-aminopyridine baits, stabilized with hydrochloric acid, were appraised in ripening cornfields being attacked by blackbirds on the Sand Lake National Wildlife Refuge., South Dakota. In 1982, i t had been discovered that 4-aminopyridine, the active agent in commercial Avitrol® baits for crop protection rapidly vaporized at summer storage and field baiting temperatures. In July, baiting lanes were created in 12 cornfields by destroying every 55th row. In August after a 3-day pretreatment period, fields were baited with Avitrol® FC Corn Chops-99 for a 2-week period when corn was most vulnerable to damage. Bait was applied from baiting lanes at the rate of 1 Ib/acre of field with an electric seeder mounted on an all-terrain cycle. Reb...
