- A01N 25/34: Shaped forms, e.g. sheets, not provided for in any other sub-group of this main group
- A01N 25/24: containing ingredients to enhance the sticking of the active ingredients
- A01N: PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF (preservation of food or foodstuff A23); BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES (preparations for medical, dental or toiletry purposes which kill or prevent the growth or proliferation of unwanted organisms A61K); PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS

## Abstract

New pesticidal compositions which dry and harden after application, said compositions consisting of at least one pesticidally active compound, at least one signal substance, at least one liquid UV absorber which is only sparingly miscible with water, at least one curable polymer which, after drying of the formulation, has a sponge-like structure or forms a porous film at least one surfactant and, if appropriate, additives. The new compositions are very suitable for combating insects and undesirable representatives of the order Acarina.

## Claims

### Claim 1

An insecticidal attract -and-kill formulation comprising
0.1 to 10% by weight of an insecticidally active compound selected from cyfluthrin, .beta.-cyfluthrin and transfluthrin,
0.01 to 1% by weight of a signal substance selected from E,E-8,10-dodecanedienol and Z-11-tetradecenyl acetate, 10 to 90% by weight of a polyvinyl acetate,
10 to 80% by weight of a UV absorber selected from a benzotriazole of the formula ##STR18## in which R.sup.3 represents methyl or C.sub.2 -C.sub.12 -alkyl,
a 2-hydroxy-4-methoxy-benzophenone of the formula ##STR19## and 2-(2-ethyl-hexyl)-2-cyano 3,3-diphenyl-2-propenoate of the formula ##STR20##
0. 1 to 4% by weight of a surfactant, and water
which, after drying the aqueous emulsion formed above, forms a sponge-like mass or a porus film.

### Claim 2 (depends on 1)

A method for combating harmful insects and undesirable representatives of the order Acarina in agriculture, forestry and in horticulture, which method comprises applying to the plants to be protected or to their habitat an effective amount of a composition according to claim 1.
