Nitrogen-Affected Florasulam and Pinoxaden Metabolism in Winter Wheat

Abstract

Aim. To create environmentally friendly technologies for agrochemicals’ integrated application, pinoxaden and fl orasulam metabolism at the nitrogen action were tested in wheat plants. Methods. High performance liquid chromatography (HPLC) of pinoxaden, fl orasulam and their metabolites in wheat plants. Results. The application of the Derby herbicide combined with Axial graminicide and nitrogen does not lead to an increase in residual amounts of fl orasulam and DE 570 BIH metabolite, while the application of Axial in mixtures with Derby herbicide and nitrogen does not cause an increase in residual amounts of major pinoxaden M04, M06 and M10 metabolites in winter wheat grain. Conclusions. The herbicidal composition of Derby, Axial and carbamide was establi shed to be safe for use in crop production. It also effi ciently controls main types of deleterious weeds in winter wheat fi elds.
