Abstract
This invention relates to a novel pesticidal, e.g., miticidal and aphicidal, method utilizing an active ingredient which is represented by the following formula: ##STR1## wherein R.sub.1 is alkyl of 8-14 carbon atoms either branched, cyclic or straight chain; and R.sub.2 is alkyl of 1-17 carbon atoms either branched or straight chain, alkenyl of 2-17 carbon atoms, cycloalkyl of 3-6 carbon atoms, alkoxy of 1-4 carbon atoms, --CH.sub.2 OCH.sub.3, --CH.sub.2 OCH.sub.2 CH.sub.3 or --CH.dbd.CH--CO.sub.2 H.
Claims7
A method for protecting plants from mites or aphids comprising applying to the plant locus to be protected a miticidally or aphicidally effective amount of a compound of the formula:
- ##STR29## wherein R.sub.1 is alkyl of 8-14 carbon atoms which are branched, cyclic, or straight chain and
- R.sub.2 is alkyl of 7-17 carbon atoms either branched or straight chain or cycloalkyl of 3-6 carbon atoms.
