Abstract

The field trials were conducted in main agro-climatic zones of Ukrainefrom 1997 to 2015 years. The wheat and barley were treated two weeks prior harvest according values of pre-harvest interval (GAP). The real quantity of glyphosate residues in wheat and barley were assessed. Residues of glyphosate in treated crops were examined by high-performance liquid chromatography (HPLC). Pesticide residues dynamics were shown to follow first order decay from which half-lives of glyphosate wheat and barley grain were derived. In all experiments, at recommended PHI, mean residues were below established and approved in Ukraine glyphosate maximum residue level. The possible daily intake of glyphosate taking into account our results was estimated. The results presented in this work and the low toxicity of glyphosate for environment proved that glyphosate will not pose any residual toxicity problem after 14 days of application and wheat and barley grain could be used safely for human consumption.
