A simple, fast and precise High Performance Liquid Chromatographic method with diode array detector was developed and single laboratory validated for the determination of mepiquat chloride in soluble concentrate pesticide formulations. From the results obtained, the repeatability of the method expressed as relative standard deviation (%RSD) was found to be 0.3%, and the limit of detection was 0.02 microg/mL. The accuracy of the whole procedure estimated by the comparison of the results obtained with the reference values, and was found to be acceptable as t(cal) < t(crit). The precision of the method also considered acceptable as the experimental repeatability relative standard deviation (RSD(r)) was lower than the interlaboratory relative standard deviation (RSD(R)), calculated by the Horwitz equation.
