DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/FR96/00132, filed Jan. 26, 1996.
The present invention relates to novel agrochemical combinations, for the protection of plants, comprising at least one effective quantity of an insecticide A from the class of the chloronicotinyls, such as imidacloprid, acetamiprid or nitenpyram, and at least one effective quantity of an insecticide B other than an organophosphorus, pyrethroid or carbamate insecticide, and to a method for treating plants using these combinations.
In the context of the present invention, the term plant refers to an entire plant, a part of the plant or the propagation material of the plant, especially the seed.
More advantageously, the subject of the invention is an agrochemical combination for the protection of plants against insects or arthropods, characterized in that an effective quantity of an insecticide comprising an insecticide A from the class of the chloronicotinyls, such as imidacloprid, acetamiprid or nitenpyram, and an insecticide B with a pyrazole, pyrrole or phenylimidazole group, is used.
Insecticides B with a pyrazole, pyrrole or phenylimidazole group include those described in the applications for European Patents EP 0295117, EP 0460940 or EP 0484165, respectively. Preferably, the insecticide chosen in the present invention is from the class of insecticides with a pyrazole group. Advantageously, the compound chosen is that whose common name is fipronil, of chemical formula (.+-.)-5-amino-1-(2,6-dichloro-.alpha.,.alpha.,.alpha.-trifluoro-p-tolyl)- 4-trifluoromethylsulphinylpyrazole-3-carbonitrile, the compound 5-amino-1-(2,6-dichloro-.alpha.,.alpha.,.alpha.-trifluoro-p-tolyl)-4-ethyl sulphinylpyrazole-3-carbonitrile or the compound 5-methylamino-1-(2,6-dichloro-.alpha.,.alpha.,.alpha.-trifluoro-p-tolyl)-4 -ethylsulphinylpyrazole-3-carbonitrile. Apart from its disclosure in the application EP 0295117, the properties of the compound fipronil have been published in the report of the 1992 Brighton Crop Protection Conference (Pests and Diseases, pages 29-34).
Imidacloprid is the common name for 1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-2-ylideneamine, the insecticidal properties of which have been described, in particular in the "Pests and diseases" reports of the 1990 Brighton Crop Protection Conference, p. 21.
Acetamiprid is the common name for (E)-N.sup.1 -((6-chloro-3-pyridyl)methyl)-N.sup.2 -cyano-N.sup.1 -methyl-acetamidine. This product is listed in the Pesticide Manual (tenth edition) under its code number NI-25. It was first disclosed in the international application PCT/JP90/01282 published under the number WO 91/04965. Since then, other properties of this compound have been described in the international application PCT/EP93/01286 published under the number WO 93/24004.
Nitenpyram is the common name for (E)-N-((6-chloro-3-pyridyl)methyl)-N-ethyl-N'-methyl-2-nitrovinylidenediam ine. This product is listed in the Pesticide Manual (tenth edition), edited by Clive TOMLIN and published by the British Crop Protection Council, 1994.
Preferably, the combinations according to the invention can be used for the protection of seeds or in treating the soil.
A further subject of the invention is compositions comprising an abovementioned combination according to the invention.
The invention additionally comprises a method for the anti-insect or anti-arthropod treatment of plants, characterized in that a combination of the two active ingredients is applied. It is also possible to apply a composition containing the two active ingredients or, either simultaneously or in succession so as to have the combined effect, two compositions each containing one of the two active ingredients.
A further subject of the invention is a method of treating seeds, characterized in that the said seed is chosen from the group consisting of cereals (e.g. wheat, barley, rye), maize, sorghum, sunflower, cotton, rice, peas, colza, potato and market-garden crops.
The application rates of the combinations of compounds according to the invention can vary within wide limits,
