Subchronic Toxicity
BETA-CYFLUTHRIN TECHNICAL
In a subchronic dietary study, dogs treated with beta-cyfluthrin, exhibited
vomiting, diarrhea, decreased body weight gain and clinical neurological
symptoms at the highes dose level (360 ppm).
In a subchronic dietary study in rats treated with beta-cyfluthrin, effects included
reduced body weight gains and feed consumption, uncoordinated gait, and skin
injuries of the neck and head from excessive preening due to the local irritant
effect of the test material.
In a 4-week inhalation study in rats exposed to beta-cyfluthrin, effects observed
included ungroomed fur, piloerection, hyper- and hypoactivity, reduced body
weight gains, hematological changes and reduced organ weights (thymus,
spleen).
IMIDACLOPRID TECHNICAL
In a 3-week dermal toxicity study, rabbits treated with imidacloprid showed no
