Application Strategy for an Anthraquinone-Based Repellent and the Protection of Soybeans from Canada Goose Depredation
Agricultural crops can sustain extensive damage caused by Canada geese ( Branta canadensis ) when these crops are planted near wetlands or brood-rearing sites. From 2000 to 2015, South Dakota Game, Fish and Parks spent >$5.6 million to manage damages caused by Canada geese to agricultural crops (...

Soybean yield was greater in subplots 73 m from the water’s edge than that in the 36-m subplots ( P < 0.02). Among subplots first sprayed at 50% seedling emergence, soybean yield was greater at 73 m and 82 m than that at 36 m ( P < 0.005).
