Algae: ErC50 for Scenedesmus subspicatus >10 mg/l. Bees: Toxic to honeybees. Worms: LC50 for Eisenia foetida >1000 mg/kg dry soil. ENVIRONMENTAL FATE Animals: Cyfluthrin was largely and very quickly eliminated; 98% of the administered amount was eliminated after 48 h via the urine and the faeces. Plants: Since cyfluthrin is not systemic, it penetrates only slightly into the plant tissues and is hardly translocated into other parts of the plant. The concentration is very low and can be neglected. Soil/Environment: Degradation in different soils is rapid. The leaching behaviour can be classified as immobile. The metabolites of cyfluthrin are subject to further microbial degradation to the point of mineralisation to CO2.
