Inclusion of the fungicide chlozolinate in a multiresidue method

A multiresidue GC method for the monitoring of electron-capturing compounds has been validated for the fungicide chlozolinate in the four crops with uses to be supported during re-evaluation procedures within the European Union. The method was also tested for a further eight crops. Matrix-matching of standards was found to be desirable to avoid the random occurrence of artificially high recoveries. The high accuracy and precision of the method, with a mean recovery of 94% and an RSD of +/-5%, shows it to be suitable for routine residue control in a wide range of crops.
