Chronic aquatic effect assessment for the fungicide azoxystrobin
This study examined ecological effects of a range of chronic exposure concentrations of the fungicide azoxystrobin in freshwater experimental systems (1270 L outdoor microcosms). Intended and environmentally relevant test concentrations of azoxystrobin were 0, 0.33, 1, 3.3, 10, 33 μg ai/L, kept at constant values. Responses of freshwater populations and community parameters were studied. Over ...

The impacts of different temperatures (20°C and 26°C) and soil moisture levels (30%, 50% and 70% of the water holding capacity) were investigated in combination with the insecticide lambda‐cyhalothrin ...
