Abstract
Abstract The invention provides a novel method for controlling various kinds of pests harmful against sanitation and agriculture by applying an organosilicon compound, never used hitherto for such a purpose, to the body of the pest or distributing the organosilicon compound over the site or field infested therewith. The organosilicon compound is a cyclic organopolysiloxane compound represented by the general formula <IMAGE> in which each of the groups R is a hydrogen atom or a monovalent hydrocarbon group independently from the others, at least one of the groups denoted by R in a molecule being a monovalent hydrocarbon group, and n is an integer in the range from 3 to 7.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
97 words
A method for controlling insects which comprises applying an insecticidally effective amount of a cyclic organopolysiloxane compound which is liquid at room temperature having the formula ##STR4## in which R may be the same or different and is a hydrogen atom, or a monovalent hydrocarbon group selected from the group consisting of alkyl, cycloalkyl, alkenyl, aryl, aralkyl and halogen substituted aralkyl, wherein at least one of the groups denoted by R is a monovalent hydrocarbon group, and n is an integer from 3 to 7, directly to the pests or to a site infested with the pests.
Claim 2
Independent Claim
97 words
