ENVIRONMENTAL FATE:
Animals Quickly and efficiently eliminated (mainly via excreta) and extensively metabolised in all species tested (rats, farm animals), without accumulation in most major animal food products. The metabolic pathways are similar for all species. Pymetrozine is the relevant residue for assessing the consumer exposure to treated animal food products. Plants The basic degradation steps are similar in all investigated crops; pymetrozine is the only relevant compound for residue definition. Soil/Environment In soils, very rapidly and strongly adsorbed, with low mobility and low leaching potential. Soil DT50 2-69 d, DT90 55-288 d. Rapidly degraded in slightly acidic or sunlight-exposed surface water; DT50 in surface water (typical value) 7 d. Slightly volatile. Efficiently removed by direct photolysis and photochemically induced oxidation.
