Safety Evaluation of Brofluthrinate to Environmental Organisms

The toxicit ies of brofluth rinate to 7 species of environmental organisms and their safety evaluation were studied, acco rding to“Experimental Guideline fo r Environmental Safety Evaluat ion of Chem ical Pest i-cides”1 . The results show ed that the toxicity of brofluth rinate to birds, bees and earthworms is low , to fish is medium , and to Daphnia, alga, silkworms is high. The actual harm to the aquatic organisms is very low when used in the fields, because of the little do sage and quick degradation. But the pollut ion to the nearby mulberry must be strictly prevented so as not to influence the growth of silkworms.
