Description of key information
The effects of the substance on terrestrial organisms were investigated with soil macroorganisms, soil microorganisms, arthropods, terrestrial plants and birds.
The overall long-term NOEC for the soil macroorganisms except arthropods (Eisenia fetida) is <1.15 mg a.s./kg dry weight soil.
The 28-day EC50 and NOEC for terrestrial arthropods (Folsomia candida) exposed to the present test material were 0.76 and 0.32 mg a.s./kg dry weight soil.
The EC50 (14 d), determined in a vegetative vigour and in a seedling emergence studies, conducted with ten differentes species, was 225 g a.s./ha (the highest tested rate) equivalent to 0.3 mg a.s./kg dws.
Furthermore, the substance showed no effect on nitrogen transformation of the soil microflora up to 1 mg a.s./kg dry soil.
Additional information
The chronic toxic effect of the test substance on earthworms, arthropods and plants resulted in a NOEC ranging from 0.3 to 148.5 mg a.s./kg dry weight soil.
Regarding the acute effects, Aphidius rhopalosiphi resulted in the lowest mortality endpoint with a LC50 equivalent to 0.001448 mg a.s./kg dry weight soil.
Furthermore, the substance showed no effect on nitrogen transformation of the soil microflora up to 1 mg a.s./kg dry soil.
Pollinator studies, investigating acute and chronic toxicities on adult and chronic toxicity on larvae, resulted in an overall LD50 value of 3.79 ng a.s./bee, an overall LDD50value of 1.83 ng a.s./bee/day and an overall NOEC of > 40000 ng a.s./kg diet.
The overall NOEC regarding birds dietary toxicity was 500 mg a.s./kg feed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
