or the corresponding unsaturated compound thereof having the formula:
<Chemistry id="chema02" num="0002"><Image id="ia02" he="37" wi="49" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>
wherein R, R', R" and R''' each are lower alkyl or hydrogen; wherein y is an integer from 1-3, and x and z each are 0 or 1, with the proviso that y is 1 or 2 when x is 1; and a carrier. A method of using such a repellent composition to repel an insect from a situs comprises applying to such situs an effective amount of the composition, with or without the carrier, and thereby repelling the insect from the situs.</p> |
