Evaluation of methyl anthranilate and activated charcoal as snow goose grazing deterrents

Bccausc greater snow geese (Chen caerulescens) damage grain crops and turf grass throughout the eastern United States, repellents are being sought. In the present experiment, 12 0.4-ha study plots were treated with methyl anthranilate (Rejex-It AC-36@, 3.4 kg a.i.), an aqueous slurry of activated charcoal (Anjan-activaid @, 3.4 kg a.i.), or left unsprayed, as a control. Both methyl anthranilate and activated charcoal significantly reduced feces within plots for 16 days post-treatment compared to unsprayed plots. Methyl anthranilate and activated charcoal appear to be promising candidate repellents to deter grazing by snow geese.
