An effective, environmentally, friendly insecticide and method of
application are described herein. The conventional insecticide d-limonene
is combined with diacetone alcohol to enhance its lethal properties. An
emulsion concentrate is first prepared using d-limonene, diacetone
alcohol, polyglycol ether and methyl soyate. This concentrated emulsion
mixture can then be stored for use as needed. When needed this
concentrated emulsion is mixed at a ratio of 10 parts by weight emulsion
and 90 parts by weight of water to form an effective mixture for spraying
in a modified manual garden sprayer having two spray wands.
