This method is applicable to:
- water-insoluble chemicals which are being studied as active ingredients;
- organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates;
- organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and
