Potential Exposure
Pyridaben is a pyridazinone insecti-
cide/acaricide/miticide used to control mites, whiteflies,
leafhoppers and psyllids on fruit trees, vegetables, orna-
mentals and other field crops. It is also used to control
pests in apple, grapes, pear, pistachio, stone fruits, and the
tree nuts group .
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. Give artificial respiration if
victim is not breathing. Do not use mouth-to-mouth
method if victim ingested or inhaled the substance; give
artificial respiration with the aid of a pocket mask
equipped with a one-way valve or other proper respiratory
medical device. Administer oxygen if breathing is diffi-
cult. Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin
or eyes with running water for at least 20 minutes. For
minor skin contact, avoid spreading material on unaffected
skin. Keep victim warm and quiet. Effects of exposure
(inhalation, ingestion or skin contact) to substance may be
delayed. Ensure that medical personnel are aware of the
material(s) involved and take precautions to protect
themselves.

oxoacids, epoxides.
Description
Pyridaben is an insecticide and acaricide. It has a low aqueous solubility, relatively volatile and, based on its chemical properties, is not expected to leach to groundwater. It tends not to persist in soils or water systems. It is moderately toxic to mammals and not expected to bioaccumulate. It is highly toxic to most aquatic organisms and honeybees but less so to earthworms and birds.
Chemical Properties
Beige Solid
Chemical Properties
White to tan crystalline solid or powder.
Faint vanilla odor. Commercial product is available as an
emulsifiable concentrate or wettable powder.
Waste Disposal
It is the responsibility
of chemical waste generators to determine the toxicity and
physical properties and of a discarded chemical and to
properly identify its classification and certification as a haz-
ardous waste and to determine the disposal method. United
States Environmental Protection Agency guidelines for the
classification determination are listed in 40 CFR Parts
261.3. Additionally, waste generators must consult and
follow all regional, national, state and local hazardous
waste laws to ensure complete and accurate classification
and disposal methods. Follow recommendations for the
disposal of pesticides and pesticide containers. Containers must be disposed of properly by following package
label directions or by contacting your local or federal
environmental control agency, or by contacting your
regional EPA office.
Definition
ChEBI: Pyridaben is a pyridazinone, an organochlorine insecticide and an organochlorine acaricide. It has a role as a mitochondrial NADH:ubiquinone reductase inhibitor.
Agricultural Uses
Insecticide, Acaricide: Used to control mites, whiteflies, leafhoppers and psyllids on fruit trees, vegetables, ornamentals and other field crops. Pyramite is a selective contact miticide/insecticide that controls pests in apple, grapes, pear, pistachio, stone fruits, and the tree nuts group[83].
