Poisonous materials, Technical Name Required. | | Incompatibilities | May form explosive mixture with air.
Strong oxidizers, strong bases, soluble mercury, other
pesticides, and water. | | Waste Disposal | The thiono-and thiolo-isomers of
this mixture are 50% hydrolyzed in 75 minutes and 0.85 min-
ute, respectively @ 20℃
and pH 13. At pH 9 and 70 ℃
, the
half-life of Demeton is 1.25 hour, but an pH 1-5 it is over
11 hours. Sand and rushed limestone may be added together
with a flammable solvent; the resultant mixture may be burned
in a furnace with afterburner and alkaline scrubber
.In
accordance with 40CFR165, follow recommendations for the
disposal of pesticides and pesticide containers. Must be dis-
posed properly by following package label directions or by
