ABSTRACT:

The present invention relates to long-acting compositions against wood-destroying insects, to their preparation and to their use.
It is known that the duration of action of crop protection agents can be extended by binding active compounds chemically to hydroxyl-group-containing wood derivatives such as sawdust, bark or lignin. However, to prepare the appropriate wood derivative/active compound complexes, complicated chemical reactions were required (Tappi/August 1971, Vol. 54, No. 8 p. 1293-1294; FR-P 1 544 406).
It is furthermore known that the action of insecticides can be extended by applying them to the soil shortly after a fertilization with organic fertilizers such as manure, compost, etc. (Archives of Environmental Contamination and Toxicology (1996) Vol. 31, No.1 p. 98-106).
Furthermore, it is known that UV-sensitive crop protection agents can be protected against UV-induced degradation by addition of lignin (WO 97/15 187).
Furthermore, it is known that polyoxyalkylene derivatives can be added as stabilizers to certain active compounds from the group of the nicotinoyl insecticides (EP-B 431 361).
Also known are baits against soil-dwelling insects, such as termites, which contain culture medium for fungi in addition to active compounds from the group of the nicotinoyl insecticides (ZA-P 94-7242).
For protecting wood-containing materials against destruction by insects, a long-term activity of the active compounds, in particular in the soil, is critical. Frequently, the duration of action of the insecticides employed is, owing to their degradation by soil-dwelling microorganisms, too short for protecting buildings.
The present invention relates to:
1. Compositions against wood-destroying insects, characterized in that they contain
a) insecticidally active compounds,
b) organic natural compounds or organic synthetic compounds or mixtures thereof as carrier material,
c) optionally microbicidally active compounds,
d) optionally attractants or development-inhibitory compounds for insects,
e) and optionally formulation auxiliaries.
2. Method for delaying the microbial degradation of active compounds against wood-destroying insects in soil, characterized in that the active compounds are mixed with natural organic compounds or synthetic organic compounds, optionally with microbicidally active compounds, optionally with attractants or development-inhibitory compounds for insects and optionally formulation auxiliaries.
3. Compositions according to 1, characterized in that the insecticidally active compounds used are one or more active compounds from the group of the agonists or antagonists of the nicotinic acetylcholine receptors of insects.
4. Compositions according to 1, characterized in that the insecticidally active compound used is imidacloprid.
5. Compositions according to 1, characterized in that they are used in the soil for protecting buildings.
6. Compositions according to 1, characterized in that they are employed in the soil for protecting materials and buildings against termites.
7. Compositions according to 1, characterized in that they are packaged in water-soluble polymer films, paper films or paper tubes and employed in packaged form.
8. Compositions according to 7, characterized in that after packaging they are in the form of tubes, sausages, bags, pillows, mats, blocks, ropes or cylinders.
9. Compositions according to 1, characterized in that the carrier material has a particle size of up to 0.2 mm, that the compositions are suspended in water prior to use and applied to the soil or buildings as a suspension, or mixed with foaming agents and applied to the soil or buildings as a foam.
10. Compositions according to 1, characterized in that the carrier material has a particle size of 0.2 mm to 10 mm and is scattered onto the soil or incorporated into the soil.
The compositions according to the invention contain one or more agrochemical insecticidally active compounds.
The insecticides include agonists or antagonists of the nicotinic acetylcholine receptors of insects, phosphorus-containing compounds such as phosphoric or phosphonic esters, natural and synthetic pyrethroids, carbamates, amidines, juvenile hormones and juvenile hormone-like substances.
Agonists or antanogists of the nicotinic acetylcholine receptors of insects are known, for example, from European Patent Nos. 580 553, 464 830, 428 941, 425 978, 386 565, 383 091, 375 907, 364 844, 315 826, 259 738, 254 859, 235 725, 212 600, 192 060, 163 855, 154 178, 136 636, 303 570, 302 833, 306 696, 189 972, 30 455 000, 135 956, 471 372, 302 389; German Patent Nos. 3 639 877, 3 712 307; Japanese Patent Nos. 03 220 176, 02 207 083, 63 307 857, 63 287 764, 03 246 283, 04 9371, 03 279 359, 03 255 072; U.S. Pat.
