Feasibility to include the pesticide in multiresidue methods

Multiresidue methods are cost effective and are therefore preferable to single residue methods. The majority of the pesticides authorised for use on wheat in more than 9 of 16 northern and central European MS (listed in Table 2 4) can be included in a multiresidue method. The exceptions are e.g. glyphosate and chlormequat.

Both LC and GC compounds are represented in Table 2 4. The sulfonylurea type is generally possible to include in LC methods. However, these types of pesticides can be difficult to detect, because the sulfonylurea compounds are very potent and only spread in very low amounts per hectare, resulting in low residue levels.

The triazole and pyrethroid types are possible to include in GC methods, whereas it varies for the strobilurin type whether GC or LC methods are most applicable.

It is difficult to give general recommendations on which pesticides are of greater or less relevance when analysing feeding stuff, since feed can be composed of a wide range of products and by-products.
