Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides an insecticide characterized by mixing a specific pyridazinone derivative with an active ingredient compound of a known insecticide and/or acaricide. - It relates to acaricide compositions.

[Prior art and problems] Today, the development of insecticides and acaricides for the purpose of controlling various pests such as agricultural and horticultural pests, forest pests, and sanitary pests has been widely advanced, and a wide variety of pesticides have been put into practical use. ing. However, there is a demand for a drug that satisfies all of the following, including toxicity to humans, livestock, and fish, insecticidal and acaricidal spectrum, insecticidal and acaricidal effects, and residual efficacy, but it is difficult to satisfy all of these requirements.

[Means for solving problems]

The present inventors, while proceeding with studies to develop insecticides and acaricides with superior insecticidal and acaricidal properties compared to these existing drugs, discovered that pyridazinone, a new active insecticide and acaricide, It has been discovered that the insecticidal/acaricidal composition of the present invention, which is a combination of a chemical compound and an active ingredient compound of an existing insecticide and/or acaricide, has an excellent synergistic insecticidal effect. The present invention is based on the general formula [I]: [However, in the above formula, R represents a linear or branched alkyl group having 2 to 6 carbon atoms, A represents a halogen atom, and X

CI! .

Macrolide antibiotics such as CIl tomilbemycin D (-ship name) DPX-3792: The pyridazinone derivative, which is one of the active ingredients of the insecticidal/acaricide composition of the present invention, has an activity comparable to that of conventional organochlorine insecticides. It is completely different from chemicals such as organic phosphorus insecticides, carbamate insecticides, and pyrethroid insecticides, and it kills certain insect pests at extremely low doses and has no residual effect. As a result, it exhibits a remarkable pest control effect.

However, these pyridazinone derivatives have a narrow insecticidal spectrum and do not satisfy all insecticidal properties.

On the other hand, another active ingredient compound of the insecticide/acaricide composition of the present invention is known as an active ingredient compound of insecticides and/or acaricides. However, due to the emergence of resistant insect pests and the lack of insecticidal/acaricidal spectrum and residual efficacy, the amount and frequency of spraying of these chemicals has increased, resulting in not only the control effect but also safety concerns such as toxicity to humans, livestock, and fish. There are also many problems from this point of view.

The feature of the insecticidal/acaricidal composition of the present invention is, firstly, that the insecticidal/acaricidal efficacy is clearly enhanced and the insecticidal/acaricidal composition is fast-acting compared to the case of applying each agent alone. Second, it has a broad insecticidal and acaricidal spectrum not found in existing insecticides and/or acaricides, and has a long residual effect. Thirdly, the dosage can be clearly reduced compared to when each single agent is applied.

That is, the insecticidal/acaricidal composition of the present invention has a synergistic insecticidal/acaricidal action. This synergistic insecticide
The acaricidal action is based on a synergistic effect that cannot be predicted from the insecticidal and acaricidal properties of each single agent, and the usefulness of the composition of the present invention is due to its reliable control effect against various pests, that is, its fast-acting properties. It can be said that it has a high residual effect, which means that it can exert its insecticidal and acaricidal efficacy over a long period of time.

The insecticidal/acaricidal composition of the present invention has excellent insecticidal power against Hemiptera pests such as leafhopper, Lepidoptera pests such as diamondback moth, Coleoptera pests, and sanitary pests such as Culex mosquito, and also parasitizes fruit trees and canola. It is also effective in controlling various mites such as the two-spotted spider mite, Kanzawa spider mite, false red spider mite, citrus spider mite, apple spider mite, etc., as well as mites that parasitic on animals, such as the bollworm tick, Boophilus annullitus, Amplionma maculatum, Lipicephalus avendiculatus, and the two-legged spider mite. It is.

When applying the insecticidal/acaricidal composition of the present invention, -C
It can be applied by mixing with a suitable carrier, and if necessary, emulsifiers, dispersants, suspending agents, penetrants, stabilizers, etc. can be added to form emulsions, wettable powders, flowables, powders, and granules. It can be put to practical use in any form such as a liquid, oil, or aerosol. Furthermore, other types of insecticides, various fungicides, herbicides, plant growth regulators, synergists, repellents, fragrances, etc. may be added and used as necessary.

The mixing ratio of the above-mentioned pyridazinone compound and the other active ingredient compound of the insecticide and/or acaricide is 1 part by weight of the former, and 0.001 to 100 parts by weight of the latter for boat fishing. , preferably 0.01 to 20 parts by weight.

Next, specific examples of the insecticide/acaricide composition of the present invention will be shown, but of course the invention is not limited to these.
