DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/EP95/00601, filed Feb. 20, 1995.
The present invention relates to a termite control composition for soil treatment containing a 3-cyano-1-(substituted phenyl)-pyrazole derivative and a pyrethroid compound as effective ingredients.
The pyrazoles derivatives as effective ingredients of the termite control composition of the present invention are known compounds described in European patent application 295117 as well as in international patent applications WO 93/6089 and 94/21606, which disclose that the compounds have a pesticidal effect on arthropods, vegetable nematodes, protozoan pests, and other pests. Many other pesticidal compounds can be used in combination with N-phenyl pyrazole derivatives. Pyrethroid compounds such as cyfluthrin, cypermethrin, deltamethrin, fenpropathrin, fenvalerate, and permethrin are recited among many possibilities without any reference to any specific effect in any conditions.
A first object of the instant invention is to provide synergistic compositions of 3-cyano-1-(substituted phenyl)-pyrazole derivative.
Another object of the instant invention is to provide specific compositions which have an improved activity against pests, especially against insects.
Another object of the instant invention is to provide specific compositions which have an improved activity against termites.
There are mainly two types of termite control methods: namely, wood application by applying a control agent to wood, and soil treatment by spraying a control agent on the soil and/or under the floor. For existing houses, since the application of the agent to wood is rather difficult, soil treatment is generally used. In many cases, however, termites pass through the treated layer and eat the wood, and, therefore, it is desired to develop a termite control agent which has both the termite control effect and the ability to prevent termites from passing through the pesticidally treated layer.
A further object of the instant invention is to provide a novel termite control composition (preferably for soil treatment) which has a strong termite control effect as well as the ability to prevent termites from passing through the pesticidally treated layer.
It has been found that these goals may be reached by mean of the compositions of the instant invention.
The compositions of the present invention comprise, as effective ingredients, a pyrethroid compound and a compound of formula (I) !5-R.sup.5 pyrazole (I) being an integer from 1 to 4, preferably one),
Halo before the name of a radical means that this radical may be substituted by one or more halogen atoms.
A preferred compound of formula (I) is 5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethyl sulphinyl pyrazole.
The compositions of the invention comprise a synergistically amount of active ingredients.
Pyrethroid compounds which can be used in the present invention include all kind of pyrethroids, especially pyrethroids other than cyfluthrin, cypermethrin, deltamethrin, fenpropathrin, fenvalerate, and permethrin. Advantageously, pyrethroids which can be used in the invention are compounds selected from a group consisting of the following pyrethroid compounds, even tough not limited to these pyrethroid compounds: transchrysanthemate! (RS)-2,2-dichloro-1-(4-ethoxyphenyl)-cyclopropane carboxylate! 3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl-cyclopropane carboxylate! 3RS)-3-(2,2-dichlorovinyl)-2,2-dimethyl cyclopropane carboxylate! RS,3SR)-3-(2,2-dichlorovinyl)-2,2-dimethyl cyclopropane carboxylate! 3S)-2,2-dimethyl-3-(1,2,2,2-tetrabromoethyl)-cyclopropane carboxylate! (RS)-2-(4-chlorophenyl)-3-methylbutanoate! cyclopropane carboxylate! butylate! 3RS)-(2,2-dichlorovinyl)-2,2-dimethyl cyclopropane carboxylate! 3RS)-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethyl cyclopropane carboxylate! propyl!(dimethyl)silane! oprop-1-enyl)-2,2-dimethyl cyclopropane carboxylate! ethoxycarbonyl)vinyl!cyclopropane carboxylate! (1RS)-cis, trans-2,2-dimethyl-3-(2-methyl prop-1-enyl) cyclopropane carboxylate! p
