Dialifor is a crystalline solid. The commercial
product may also be available as a colorless oil.
Nonsystemic insecticide and acaricide to control chewing and sucking insects and
spider mites on a wide variety of fruits and vegetables.
ChEBI: Dialifor is a member of isoindoles.
White crystalline solid, also reported as a colorless oil, colorless. Used as an insecticide and acaricide (kills beetles, ticks, mites, etc.).
Releases nitrogen oxides, sulfur oxides, and phosphorus oxides when heated. Readily hydrolyzed by concentrated alkali. Avoid alkali. [EPA, 1998]. Organophosphates, such as DIALIFOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Highly toxic by all routes of exposure;exhibits acute, delayed, and chronic effect;cholinesterase inhibitor; symptoms of poi-soning are similar to those of parathion,including weakness and twitching of mus-cle, headache, giddiness, dizziness, excessivesalivation, lacrimation, tightness in chest,blurred vision, slurred speech, mental confu-sion, and drowsiness; gastrointestinal effectsinclude nausea, vomiting, stomach cramps,and diarrhea; heavy exposure can lead to dif-ficulty in breathing, convulsions, and coma;median lethal doses reported in the literatureshow inconsistent and varying values.
LD50 oral (rat): 5–53 mg/kg
LD50 oral (mouse): 39–65 mg/kg
LD50 oral (rabbit): 35 mg/kg
LD50 skin (rabbit): 145 mg/kg.
DIALIFOS can cause serious symptoms and in extreme cases death by respiratory arrest.
Releases nitrogen oxides, sulfur oxides, and phosphorus oxides when heated. Readily hydrolyzed by concentrated alkali. Avoid alkali.
Poison by ingestion and
skin contact. An experimental teratogen.
Other experimental reproductive effects.
When heated to decomposition it emits
toxic fumes of SOx, POx, and NOx.
A potential danger to those involved
in the manufacture, formulation and application of this
insecticide.
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin,remove contaminated clothing and wash immediately withsoap and water. Speed in removing material from skin is ofextreme importance. Shampoo hair promptly if contaminated.Seek medical attention immediately. If this chemical hasbeen inhaled, remove from exposure, begin rescue breathing(using universal precautions, including resuscitation mask) ifbreathing has stopped and CPR if heart action has stopped.Transfer promptly to a medical facility. When this chemicalhas been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Effects may be delayed; medicalobservation is recommended.
Chemical/Physical. Though no products were identified, the hydrolysis half-lives at
20°C were 15 days and 14 hours at pH 6.1 and pH 7.4, respectively (Freed et al., 1979,
1979a).
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with dialiforyou should be trained on its proper handling and storage.Store in tightly closed containers in a cool, well-ventilatedarea away from strong bases.
UN2811 Toxic solids, organic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required.
Strong bases. Contact with oxidizers
may cause the release of phosphorous oxides. Contact with
strong reducing agents, such as hydrides, may cause the
formation of flammable and toxic phosphine gas.
Alkaline hydrolysis or
incineration. In accordance with 40CFR165, follow recom-
mendations for the disposal of pesticides and pesticide
containers. Must be disposed properly by following pack-
age label directions or by contacting your local or federal
environmental control agency, or by contacting your
regional EPA office.
