Abstract
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 1 is an alkyl of 8-14 carbon atoms either branched, cyclic or straight chain; and R 2 is alkyl or 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 2 OCH 3 , -CH 2 OCH 2 CH 3 or -CH═CH-CO 2 H.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
73 words
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: ##STR31## wherein R 1 is alkyl of 8-14 carbon atoms which are branched, cyclic, or straight chain and R 2 is alkyl of 1-6 carbon atoms either branched or straight chain, --CH 2 OCH 3 or --CH 2 OCH 2 CH 3 .
Claim 2
Independent Claim
73 words
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: ##STR31## wherein R 1 is alkyl of 8-14 carbon atoms which are branched, cyclic, or straight chain and R 2 is alkyl of 1-6 carbon atoms either branched or straight chain, --CH 2 OCH 3 or --CH 2 OCH 2 CH 3 .
