Earthworms (Eisenia foetida) were exposed to Tricyclozole 75% WP pesticides in an acute earthworm toxicity test as per OECD guideline 207. Four replicates of ten clitellated adult earthworms each were exposed to the concentrations of 31.25, 62.5, 125, 250, 500, and 1000 mg/kg dry soil. The control artificial soil with acetone and quartz sand had four replicates, with ten earthworms in each replicate. Earthworms were assessed for behavioural effects at 0, 7, and 14 days of exposure, mortality
