Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insecticide composition characterized in that it is a mixture of a specific benzoyl urea compound and active ingredient compounds of other known insecticides and acaricides.

BACKGROUND OF THE INVENTION Today, the development of insecticides for the purpose of controlling various pests such as Nk horticultural pests, forest pests, and sanitary pests is being widely advanced, and a wide variety of pesticides are in practical use.

However, it is toxic to humans, livestock, and fish.

There is a demand for a drug that satisfies all of the following: insecticidal spectrum, insecticidal effect, and residual efficacy, but it is difficult to satisfy all of these requirements.

While proceeding with the study to develop an insecticide with superior insecticidal properties compared to these existing agents, the present inventors developed a benzoyl urea compound, which is a new acting pre-meal insecticide, and an existing insecticide. It has been discovered that the insecticidal composition of the present invention in combination with the active ingredient compound of a contact in-type insecticide/acaricide has an excellent synergistic insecticidal effect.

The present invention is based on the general formula (1): (wherein A represents O11 or Fi nitrogen atom, T31d represents oxygen atom or sulfur atom, and X and X are.

independently of each other, hydrogen atoms, halogen atoms.

It represents a trifluoromethyl group or a nitrogen atom, Y and 2 each independently represent a hydrogen atom or a... No alkyl group attached.

), organophosphorus-based, 1□-bat/-to-based, amidine-based, pyrethroid-based, -organochlorine-based or organotin-based insecticides and/or acaricides; The present invention relates to an insecticide composition containing as an active ingredient at least one of the following active ingredient compounds.

The benzoyl urea compound represented by the general formula (1), which is one of the active ingredients of the insecticidal composition of the present invention, is specifically listed below, but is not necessarily limited to these. .

These compounds are compounds having known insecticidal activity as described in 2% Publication No. 72969/1983.

These compounds are obtained by condensation of the corresponding benzoyl isocyanates and aniline derivatives, preferably in the presence of an inert solvent to the reactants. As this solvent, for example, benzene, toluene, acetonitrile, pyridine, etc. can be used.

The reaction groove Jff and reaction time can be varied over a wide range depending on the starting material, but generally the reaction time is 0.5 to 24 hours at 0°C to 100°C, depending on the reaction temperature. is preferred.

Another active ingredient compound of the insecticide composition of the present invention is an active ingredient compound of an insecticide and/or acaricide and 1-
It is well known.

Specifically, its general name and structural formula are as follows, but it is not necessarily limited to C).

General name; Structural formula 0000,H.

Organophosphorus compounds such as There are carbamate compounds such as (＾). Or amidine compounds such as V. Or (pyrethroid compounds such as 7N. Or 0 (C). (DH machine tin-based compound.

The characteristics of the insecticide composition of the present invention are, firstly, that its insecticidal efficacy is clearly enhanced and a fast-acting insecticidal effect is imparted, compared to when each agent is applied alone; Second, it has a broad insecticidal spectrum not found in existing insecticides and/or acaricides, and has a long residual effect.

That is, the insecticide composition of the present invention has a synergistic insecticidal action.

This synergistic insecticidal action is based on a synergistic effect that cannot be predicted from the insecticidal properties of each single agent.

It can be said that the usefulness of the composition of the present invention lies in its reliable control effect against various pests, that is, its excellent insecticidal effect can be exerted over a long period of time, with not only immediate effect but also high residual effect.

Next, examples of insect pests to which one of the compounds of the present invention can be applied are illustrated, but of course the pests are not limited to these.

Green peach aphid [Fruit trees] Hama = t' bugs, Kinmon spp. If necessary, it can also be applied as an emulsifier, a dispersant, or a suspending agent.

By adding a penetrating agent, a stabilizer, etc., it can be put to practical use in any desired dosage form such as an emulsion, a wettable powder, a single powder, an oil solution, or an aerosol. Furthermore, other types of insecticides, various fungicides, herbicides, plant growth regulators, synergist 2 repellents, fragrances, etc. can also be used in addition, if necessary.

Next, the fact that the insecticide composition of the present invention exhibits excellent insecticidal action will be specifically explained using test examples.

On a test bench Insecticidal effect test on Spodoptera larvae The insecticidal composition of the present invention and a single control agent were dispersed in water, adjusted to a predetermined concentration, and used as a test chemical solution.

After soaking a cabbage leaf piece in this chemical solution for about 10 seconds, it was taken out and air-dried. After releasing.

It was covered and stored in a constant temperature room with lighting at 25°C.

After the larvae were released, the mortality of the larvae was determined at the third and sixth whites, and the mortality rate was calculated from the following formula iii.

The synergistic effect was determined using the formula of [Con, Ent.], Vol. 53, p. 887 (1960)].

The LC value of the control single agent is shown in Table 1, and the T, O values and synergy index of the insecticide composition of the present invention are shown in Table 2.

Note that the synergy index is expressed by the following formula.

(Based on the Sun and Ding QhIM10n method) The larger this value is than 100, the stronger the synergistic effect; when it is equal to 100, there is an additive effect, and when it is smaller than 100, there is an antagonistic effect.

Compound A in the following test examples is N-(2,6-difluorobenzoyl+-N'-(,5-(6-trifluoromethyl-2-quinoxalyloxy)phenyl)urea.
