Sunflower Treated with Avipel (Anthraquinone) Bird Repellent
Maturing sunflower (Helianthus annuus L.) is susceptible to damage by birds, especially blackbirds (Agelaius phoeniceus and Quiscalus quiscula). The National Sunflower Association (NSA) identified Blackbird damage as a major issue in the production of sunflower throughout the US. In 2007 bird damage was identified as the number one yield limiting factor in 9% of surveyed fields in North Dakota (Graph 1)
