Abstract
Specific sucrose esters have been found to act as effective, environmentally-safe pesticides against soft-bodied arthropod plant pests. These compounds have acyl substituents having up to 10 carbon atoms and are easily extractable from Nicotiana plants. The compounds are used as a mixture, as extracted from the plants, and are spray-applied as an emulsion in water.
Claims21
A compound having the structure ##STR2## wherein R.sub.1 and R.sub.2 are each independently aliphatic groups which are straight chain or branched alkyl chains having 1 to 10 carbon atoms and R.sub.3 is --OH or --O.sub.2 CCH.sub.3.
