ABSTRACT:
There are disclosed novel avermectin reduction products. The compounds are prepared by selective catalytic hydrogenation of avermectin-like compounds or by reaction of selected double bonds with electrophylic reagents. The reduced avermectin compounds have utility as anti-parasitic agents and compositions for that use are also disclosed. The compounds are also highly potent insecticides against agricultural pests. The reduced avermectin compounds have increased stability towards light which prolongs their insecticidal activities when applied to field crops subject to irradiation by sunlight.
