“…Nonlethal chemical repellents are a socially acceptable approach to managing avian depredation of agricultural crops (Cummings et al, 2002a(Cummings et al, , 2002bLinz et al, 2006;Werner et al, 2011). Previous studies assessing chemical repellents, for ripening field and sweet corn, have shown mixed results in reducing damage by birds (Woronecki et al, 1981).…”

a b s t r a c tWildlife repellents provide a non-lethal alternative for managing agricultural impacts associated with wildlife depredation. To evaluate a potential bird repellent for ripening corn, we conducted a feeding experiment at the United States Department of Agriculture, National Wildlife Research Center with 66 red-winged blackbirds (Agelaius phoeniceus). Using a two-choice experimental design we tested the efficacy of Avipel repellent (a.i. 50% 9,10-anthraquinone) on ripening sweet corn. Red-winged blackbirds consumed an average of 8.6% ± 0.9% of kernels from untreated ears and 5.3% ± 1.1% from ears treated with anthraquinone. The interaction between anthraquinone concentration and corn treatment suggests a positive concentration-response for red-winged blackbirds. Odds ratio analysis suggests red-winged blackbirds were 1.4 times more likely to damage untreated sweet corn compared to treated sweet corn. These results suggest efficacy of anthraquinone-based products as red-wing blackbird repellents for ripening corn. Moreover, exposure to anthraquinone-based repellents may reduce consumption of a food matrix that receives little to no direct anthraquinone exposure. Supplemental research is recommended to evaluate anthraquinone-based repellents under field conditions, including the establishment of a chemical tolerance for food and feed use.Published by Elsevier B.V.

“…Depredating blackbirds (Icterids) can negatively impact growth of newly planted rice in the mid-South of the United States and production of ripening rice and sunflower (Cummings et al 2002;Avery et al 2005;Werner et al 2005Werner et al , 2007Werner et al , 2008a. Cummings et al (2005) estimated that blackbirds caused approximately US$13.4 million of damage to United States rice production in 2001.…”

: Nonlethal alternatives are needed to manage blackbird (Icterids) damage to rice and sunflower production in the United States. We evaluated 4 registered fungicides on rice seeds (i.e., Allegiance® FL, Thiram 42‐S, Trilex®, and Vitavax® 200 preplant seed treatments) and 2 foliar pesticides on sunflower seeds (Cobalt™ insecticide and Flock Buster bird repellent) as candidate blackbird repellents. Red‐winged blackbirds (Agelaius phoeniceus) preferred untreated rice relative to rice treated with Thiram (P < 0.001) and Vitavax (P < 0.001), and untreated sunflower relative to sunflower treated with Cobalt (P < 0.001). Blackbirds preferred untreated sunflower relative to sunflower treated with Flock Buster repellent on day 1 of a 4‐day preference test (P < 0.001). We observed no difference in consumption of treated versus untreated rice during the Allegiance preference test (P = 0.928), and blackbirds preferred rice treated with Trilex relative to untreated rice (P = 0.003). Although repellency was positively related to tested concentrations of Thiram (P = 0.010), Trilex (P = 0.026), and Vitavax (P < 0.001), maximum repellency was < 50% during our concentration‐response tests of these seed treatments. Repellency was also positively related to tested concentrations of Cobalt (P < 0.001), and we observed >80% repellency of sunflower treated with Cobalt at ≥50% of the label rate. We observed no concentration‐response relationship for the Allegiance seed treatment (P = 0.341) and Flock Buster repellent (P = 0.952). We recommend implementation of supplemental field studies to compare laboratory efficacy, repellency, and chemical residues of effective avian repellents throughout periods of needed crop protection.

“…Red‐winged blackbirds have consistently demonstrated repellency to AQ‐treated rice seed. Repellency has been positively associated with AQ concentrations as low as 50 mg AQ kg −1 and up to 20 000 mg AQ kg −1 , regardless of the tested product . A threshold concentration of 4921 mg AQ kg −1 on rough rice was predicted for 80% repellency in red‐winged blackbirds; this concentration also causes conditioned avoidance in investigations of sensory cues .…”

“…Field testing of AQ‐treated rice seed in water‐seeded field tests in Louisiana demonstrated that rice seed treated with 7100–8800 mg AQ kg −1 at planting was effective for blackbird repellency . Anthraquinone‐treated plots had higher plant density than control plots at the conclusion of the study, and bird activity within control plots was twice that observed within treated plots .…”
