Division 6.6.1 Metabolism in rotational crops

The objectives of metabolism studies in rotational crops shall be:

1. (a)

   to provide an estimate of the total terminal residues in the relevant portion of crops at harvest of rotational crops following treatment of the preceding crop as proposed;

2. (b)

   to identify the major components of the total terminal residue;

3. (c)

   to indicate the distribution of residues between relevant crop parts;

4. (d)

   to quantify the major components of the residue;

5. (e)

   to indicate additional components to be analysed for in residue quantification studies (field crop rotation studies);

6. (f)

   to decide on restrictions in crop rotation; and

7. (g)

   to decide on the necessity of field residue trials in rotational crops (limited field studies).
