Extended
laboratory tests
Eurofins Agroscience Services conduct extended laboratory studies according to the recent IOBC/WPRS
guidelines with parasitoids (Aphidius rhopalosiphi,
Trichogramma cacoeciae), predatory mites (Typhlodromus pyri,
Phytoseiulus persimilis), aphidophagous predators (Chrysoperla carnea,
Coccinella septempunctata) and
anthocorid bugs (Orius laevigatus).
Standard studies are usually performed in Southern Germany.
Depending on the climatic conditions and the time schedule, as well as
the crop (e.g. citrus) in which the product should be tested, aged
residue studies are located in Spain and can be conducted between March
and November.
Standard studies can be performed throughout the year,
provided that plants can be cultivated indoor (laboratory, greenhouse)
during winter. Aged residue studies can be conducted between May and
October (last applications August/September).
The choice of the plants depends on the crop where the
tested product is used and/or suitability for the test organism. Most
frequently apple (Malus), vine (Vitis vinifera), cereals,
e.g. barley (Hordeum vulgare) and dwarf bean (Phaseolus
vulgaris) are used. Besides, leaves of broad bean (Vicia faba),
maize (Zea mays), sweet pepper (Capsicum annuum), cabbage
(Brassica oleracea), e.g. broccoli, or sugar beet (Beta
vulgaris) can serve as substrate for exposure. |
Standard test
Test organisms are exposed to treated plant material (detached leaves, leaf discs or whole plants) under laboratory conditions. Plants are sprayed in the laboratory, in the field or outdoor near the testing facility using field application equipment. |
