effect on germination rate. DMSO has no effect on the growth rate of corn when sprayed on at
rates up to 30 gallon/acre. When diluted with a large amount of water, release of DMSO,
directly or indirectly, to the environment is not expected to have significant effect.
Dilute and flush to an approved wastewater treatment system. Bacterial decomposition of
dimethyl sulfoxide during wastewater treatment can result in the release of dimethyl sulfide (a
volatile substance with a strong disagreeable odor). Waste DMSO can also be incinerated in an
approved furnace where permitted. Consult federal, state or local authorities for proper
disposal procedures.
Should be transported/delivered using a registered waste carrier for recycling or waste disposal
in accordance with local regulations.
