Sequential testing programmes with non-target arthropods are designed to demonstrate the inherent toxicity (or lack of it) of plant protection products and biocides to key indicator species.
Testing normally commences with laboratory (Tier I) studies using the mandatory species (for Europe) of Aphidius rhopalosiphi and Typhlodromus pyri. Extended-laboratory (Tier II) and aged residue studies may then follow, if triggered by toxicity demonstrated in the previous tier of testing. Field testing is the highest tier.
Mambo-Tox can also work with other non-target species, mostly to provide data for IPM purposes.
Laboratory studies using an inert test substrate (glass). These are typically of a rate-response design, to determine the median lethal rate (LR50) for a test item, for inclusion in Hazard Quotient calculations.
TIER II (EXT-LAB) AND AGED RESIDUE
Tier II (Ext Lab) - Extended laboratory studies using a natural test substrate (plant leaves or standard natural soils).
Aged Residue - Aged-residue studies, the aim of which is to determine the decline in activity of harmful treatments applied to plants or soil, which are aged outdoors under rain-protection, permeable to UV-light.
Listed below are some of the most widely used tests provided by the laboratory. In addition to these Mambo-Tox has an extensive portfolio of other tests and, where appropriate, can develop specific tests and analytical suites for your business.
