Camouflage of Seeds, a Control Method of the Bird Mortality in Grain Crops

This chapter discusses the development of a mitigation measure against impacts caused by the ingestion of poisoned seeds by insecticides like carbofuran and carbosulfan in wheat, corn and rice fields. In accordance with Brazilian Federal Decree no 4.074 of January 2002, agrotoxins should be added to seeds mixed with dye to avoid the risk of being ingested by humans. The toxic dye rhodamine B, whose reddish-purple colour has been used for this purpose, it’s apparent and attractive to granivorous wild birds such as Columbidae and Icterinae.
