TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Lannate SP
Lannate SP is not a skin irritant or a skin sensitizer, but is a
slight eye irritant in animals.
Effects of a single eye exposure included mortality, pupillary
constriction of the treated eye, tremors, convulsions, salivation,
lethargy, rales, and fasiculations. These clinical signs were
present only on the day of treatment.

Methomyl
Inhalation 4 hour LC50: 0.258 mg/L in rats
Skin absorption LD50: > 2,000 mg/kg in rabbits
Oral LD50: 34 mg/kg in male rats
Oral LD50: 30 mg/kg in female rats
Methomyl is not a skin irritant or a skin sensitizer, but is a
mild eye irritant in animals.
Effects of a single inhalation exposure to Methomyl include weight
loss, diarrhea, lethargy, as well as temporary decreased plasma
cholinesterase activity, abnormal gait, hyperactivity and tremors.
Corneal opacity was noted in one rat exposed to near-lethal
concentrations.
Effects of a single dermal exposure to Methomyl include rapid
respiration, miosis and nervous system effects such as tremors.
Repeated exposure produced labored breathing, and nervous system
effects such as miosis and depression.
A single ingestion exposure to Methomyl produced nervous system
effects as described for inhalation and skin exposures. Repeated
oral exposure produced signs of nervous system effects similar to
acute studies. Feeding studies in rats and mice produced only
mild effects having no clear toxicological significance.
Long-term feeding studies via the diet produced lowered red blood
counts and hematocrit, indications of nervous system effects, and
histopathological changes in kidneys, spleen, liver and bone
marrow.
In a 91-day oral neurotoxicity study in rats, most of the effects
observed appeared to be acute in nature. There were no
morphological changes in the nervous system.
Ocular exposure with Methomyl caused pupillary constriction,
incoordination, tremors, convulsions, profuse salivation,
lethargy, rales, and/or fasciculations were also observed in
rabbits approximately 1 and 20 minutes after treatment with 10 mg
of methomyl. Pupillary constriction was still evident after 1
hour. These clinical signs are typical of anticholinesterase
activity. These effects were not present the day after treatment.
Tests in animals demonstrate no carcinogenic, developmental, or
reproductive toxicity.
Methomyl does not produce genetic damage in animals or in
bacterial and mammalian cell cultures.
