| Chemical Properties | Slightly soluble in water. Soluble in mostorganic solvents. |
| Chemical Properties | Demeton-methyl is a colorless to pale yellow
oily liquid. Unpleasant odor. It is a mixture of Demeton-S
and Demeton-O and may be formulated in a flammable
organic solvent that may alter the physical properties
shown here. |
| Uses | Systemic insecticide. |
| Uses | Demeton Methyl is an organophosphorus pesticides. |
| General Description | Oily colorless to pale yellow liquid with an unpleasant odor. Slightly water soluble. |
| Air & Water Reactions | Slightly water soluble. Hydrolyzed by alkali . |
| Reactivity Profile | Organothiophosphates, such as Demeton methyl powder(content>10%), 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. |
| Hazard | Cholinesterase inhibito. Use may berestricted, absorbed by skin. |
| Fire Hazard | Flash point data for Demeton methyl powder(content>10%) are not available. Demeton methyl powder(content>10%) is probably combustible. |
| Potential Exposure | An organophosphate insecticide.
Those engaged in the manufacture, formulation and appli-
cation of the insecticide and acaricide on agricultural and
horticultural crops. |
| Shipping | UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1;
Labels: 6.1-Poisonous materials, Technical Name Required. |
| Incompatibilities | ncompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or
explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, and epoxides. Strong oxidi-
zers may cause release of toxic phosphorus oxides.
Organophosphates, in the presence of strong reducing
agents such as hydrides, may form highly toxic and
flammable phosphine gas. Keep away from alkaline
materials. |
| Waste Disposal | Alkaline hydrolysis or
incineration
. In accordance with 40CFR165, follow
recommendations for the disposal of pesticides and pesti-
cide containers. Must be disposed properly by following
package label directions or by contacting your local or
federal environmental control agency, or by contacting
your regional EPA office. |
