Abstract
Substituted benzodioxoles of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are hydrogen or alkyl of 1 to 6 carbon atoms or together with the linking carbon atom form a cycloalkane or cycloalkene ring of 5 to 7 carbon atoms; R.sup.3 is hydrogen, alkyl of 1 to 4 carbon atoms or acyl; R.sup.4 is alkyl of up to 4 carbon atoms, alkenyl of up to 4 carbon atoms or alkynyl of up to 4 carbon atoms; and R.sup.5, r.sup.6 and R.sup.7 are hydrogen, halogen or alkyl of 1 to 4 carbon atoms Are valuable pesticides, particularly insecticides.
Claims33
A pesticidal composition for combating insects and acarids comprising a pesticidal amount of a compound of the formula ##STR4## wherein R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen and alkyl of 1 to 6 carbon atoms and a group where R.sup.1 and R.sup.2 together with the linking carbon atom form a cycloaliphatic ring selected from the group consisting of cycloalkane and cycloalkene rings of 5 to 7 carbon atoms;
- R.sup.3 is selected from the group consisting of hydrogen, alkyl of 1 to 4 carbon atoms and lower alkanoyl;
- R.sup.4 is selected from the group consisting of alkyl of 1 to 4 carbon atoms, alkenyl of up to 4 carbon atoms and alkynyl of up to 4 carbon atoms;
- and
- one of R.sup.5, R.sup.6 and R.sup.7 are selected from the group consisting of hydrogen, halogen and alkyl of 1 to 4 carbon atoms, and wherein the remaining members of R.sup.5, R.sup.6 and R.sup.7 each represent hydrogen in combination with at least one material selected from the group consisting of carriers, wetting agents, and mixtures thereof.
A method of combating insect and acarid pests which comprises applying to a locus a pest-combating amount of a compound of the formula ##STR6## wherein R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen and alkyl of 1 to 6 carbon atoms and a group where R.sup.1 and R.sup.2 together with the linking carbon atom form a cycloaliphatic ring selected from the group consisting of cycloalkane and cycloalkene rings of 5 to 7 carbon atoms;
- R.sup.3 is selected from the group consisting of hydrogen, alkyl of 1 to 4 carbon atoms and lower alkanoyl;
- R.sup.4 is selected from the group consisting of alkyl of 1 to 4 carbon atoms, alkenyl of up to 4 carbon atoms and alkynyl of up to 4 carbon atoms;
- and
- one of R.sup.5, R.sup.6 and R.sup.7 are selected from the group consisting of hydrogen, halogen and alkyl of 1 to 4 carbon atoms, and wherein the remaining members of R.sup.5, R.sup.6 and R.sup.7 each represent hydrogen.
