Soil macro-organism Studies

i2LResearch offers a full range of soil macro-organism studies: Earthworm laboratory acute toxicity (OECD 207) and reproduction (OECD 222) tests with Eisenia fetida, reproduction testing with Collembola (OECD 232) and Hypoaspis mites (OECD 226).

Full scale field testing

In addition to full scale field testing with earthworms, Collembola and mites, i2LResearch also offers a range of full fauna field studies with non-target arthropods (NTAs) in a variety of agricultural crops, following ISO 11268-3 and ISO 23611-2.

  • Acute contact and oral laboratory testing (OECD 213/214 and EPA OCSPP 850.3020)
  • Bee larval toxicity (OECD 237)
  • Chronic oral and accumulative toxicity (EFSA 3295)
  • Semi-field bee testing (EPPO PP/170(4) and OCSPP 850.3040

Non Target Plant testing (NTPs)

We offer non target plant testing on seedling emergence (OECD 208) and vegetative vigour (OECD 227).
