Spinetoram (11.2%) . The active ingredient in Cheristin is spinetoram, registered in 2007 for use on a variety
of fruits and tree nuts. The introduction of spinetoram for use in agriculture resulted in
the receipt of a Presidential Green Chemistry Award3
in 2008. The award was presented
to Dow AgroSciences LLC. In the context of agricultural use, spinetoram has a lower
environmental impact than do many current insecticides because both its use rate and
toxicity to non-target species is low.
