States, which was published by the International Bureau in English
as WO 95/22902 on Aug. 31, 1995. applications Ser. Nos. 09/457,861,
09/268,686 and 08/855,606 are incorporated by reference herein in
their entireties and relied upon.
[0002] 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.
[0003] The pyrazole derivatives as effective ingredients of the
termite control composition of the present invention are known
compounds described in European patent publication 0295117 as well
as in the international patent publications WO 93/06089 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.
[0004] A first object of the instant invention is to provide
synergistic compositions of 3-cyano-1-(substituted phenyl)-pyrazole
derivatives.
[0005] Another object of the instant invention is to provide
specific compositions which have an improved activity against
pests, especially against insects.
[0006] Another object of the instant invention is to provide
specific compositions which have an improved activity against
termites.
[0007] 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.
[0008] 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.
[0009] It has been found that these goals may be reached by means
of the compositions of the instant invention.
[0010] The compositions of the present invention comprise, as
effective ingredients, a pyrethroid compound and a compound of
formula (I)
1-[4-R.sup.12,6-(R.sup.2).sub.pphenyl]3-cyano-4-[R.sup.4-S(O).sub.n]5-R.su-
p.5pyrazole (I)
[0011] wherein:
[0012] R.sup.1 is halogen, lower haloalkyl, lower haloalkoxy or
SF.sub.5 (lower being an integer from 1 to 4, preferably one),
[0013] R.sup.2 is halogen, the various R.sup.2 being identical or
different,
[0014] R.sup.4 is halogen, lower alkyl or haloalkyl,
[0015] R.sup.5 is halogen, lower alkyl or amino,
[0016] n is 0 or 1 or 2; p is 1 or 2 or 3 or 4, preferably 2.
[0017] Halo before the name of a radical means that this radical
may be substituted by one or more halogen atoms.
[0018] A preferred compound of formula (I) is
5-amino-3-cyano-1-(2,6-dichl-
oro-4-trifluoromethylphenyl)-4-trifluoromethylsulphinylpyrazole
(Compound A).
[0019] The compositions of the invention comprise a synergistic
amount of active ingredients.
[0020] Pyrethroid compounds which can be used in the present
invention include all kinds of pyrethroids, especially pyrethroids
other than cyfluthrin, cypermethrin, deltamethrin, fenpropathrin,
fenvalerate, and permethrin. Advantageously, pyrethroids which can

Test Example 1
[0067] A testing apparatus was used in which two glass cylinders
(each about 5 cm in diameter and about 12 cm in height) are
connected at about 2 cm from the bottom with a glass tube about 1.5
cm in diameter and about 10 cm in length (graduated at 5-mm
intervals for 5 cm at the center). The one glass cylinder was
filled with about 60 g of non-treated soil adjusted to a moisture
content of about 25%, and the other glass cylinder was filled with
about 0.29 g of filter paper (5.5 mm in diameter). The glass tube
was filled, at a thickness of 1 cm, with test soil prepared by
mixing 2.4 g of non-treated sandy soil which had passed through a
20-mesh screen and had been dried at 60.degree. C. until a constant
weight had been achieved, with 0.45 g of the solution of the test
composition of a predetermined concentration, and the mixture was
allowed to stand for 3 weeks in a room without weather resistance
treatment. The glass tube was connected to the glass cylinders.
[0068] In the glass cylinder filled with non-treated soil, 200
workers and 20 soldiers of Coptotermes formosanus Shiraki were
placed, and the testing apparatus was kept at a constant
temperature chamber controlled at a temperature of 28.degree. C.,
and a relative humidity of 70% or higher.
[0069] The bored depth (millimeters=mm), damage by eating, and the
termite control effect were determined 14 days after insects were
put in place, and the effect was evaluated in accordance with the
following criteria:
[0070] Damage by eating:
4 + 10% or less compared with non-treatment ++ 11-50 % or less
compared with non-treatment +++ 51% or more compared with
non-treatment
[0071] Termite Control Effect:
5 A 100% lethal B 80-99% lethal C 50-79% lethal D 49% lethal or
less
