Abstract
There are disclosed novel formulations of avermectin compounds and a substrate which demonstrate markedly enhanced insecticidal activity over that which would be observed with other formulations. Avermectin natural product compounds and certain semisynthetic derivatives thereof are compounds known to be highly effective broad-spectrum antiparasitic and pesticidal agents. However, when such compounds are formulated into the instant composition, the activity observed is increased to at least 10-times that which would be expected. The instant substrate is preferably a highly dispersed, amorphous form of hydrophyllic silicon dioxide.
