A modified method for determination of dithiocarbamate residue recoveries from grain was studied collaboratively. In this method dilute acid with stannous chloride is added to the crop, which is then heated to boiling for the dithiocarbamate decomposition step. A mixture of NaOH solution and benzene is used to trap hydrogen sulfide and other volatile interferences. Collaborative results were low and erratic, with large coefficients of variation. The results of the Associate Referee, on the other hand, were better. Further study on this method is recommended.
