Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pest control material, and more particularly to a pest control material capable of controlling pests without spraying an insecticide.

[0002]

2. Description of the Related Art A pest control material is known in Japanese Patent Laid-Open No. 5-236856, in which an insect growth control agent is carried on a substrate having a color that attracts pests. ing. However, since this pest control material may not always exhibit sufficient efficacy, development of a better pest control material is desired.

[0003]

Means for Solving the Problems As a result of studies to solve the above problems, the present inventors have found that a surface of a base material having a color that attracts pests has the formula (A).

[Chemical 2] 5-chloro-6- (1-fluoroethyl)-
N- [2- [4- (trifluoromethoxy) phenyl]
The inventors have found that the pest control material carrying ethyl] pyrimidin-4-ylamine has sufficient efficacy against a wide range of pest species with a small amount of active ingredient, and completed the present invention.

That is, according to the present invention, a substrate whose surface has a color that attracts pests is represented by the formula (A): 5-chloro-6-
There is provided a pest control material comprising (1-fluoroethyl) -N- [2- [4- (trifluoromethoxy) phenyl] ethyl] pyrimidin-4-ylamine.

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, 5-chloro-6- (1-fluoroethyl) -N- represented by formula (A)
[2- [4- (Trifluoromethoxy) phenyl] ethyl] pyrimidin-4-ylamine (hereinafter referred to as the present compound) is a compound described in JP-A-7-258223, and is according to the description in the publication. Can be manufactured.

In the pest control material of the present invention, the pests to be controlled are mainly pests that harm crops, and specific examples thereof include whiteflies [Onales whitefly (Trialeurod).
es vaporariorum), Tobacco whitefly (Bemisia taba)
ci), Silver Leaf Whitefly (Bemisia argentifol)
ii)], Leafhopper leafhopper (Arboridia apicali
s), aphids [Aphis gossypi
i), green peach aphid (Myzus persicae), radish aphid (Bervicoryne brassicae), black radish aphid (Lipaphis erysimi), wheat aphid (Rhopalosiphumpadi), rice aphid (Tox).
optera aurantii), pea aphid (Acr)
ythosiphon pisum) and other hemiptera pests, Thrips palmi, Thrips palmi, Thrips thrips (Scirtothrips dorsalis), Thrips thrips (Frankliniella intonsa), etc.,
Diamondback moth (Plutella xylostella), Lepidopteran pests such as Parnara guttata, Dascucurbitae, and mushroom flies (Mycetophilida)
e), dipteran pests such as bean leafhopper (Liriomyza trifolii) and onion fly (Delia antiqua).

These pest-damaging pests are usually attracted to yellow to blue. Here, yellow to blue means colors such as yellow, yellow-green, green, turquoise, and blue whose main wavelengths of reflected light rays correspond to about 650 to 420 nm. In particular, whitefly, whitefly, tobacco whitefly, silver leaf whitefly, leafhopper leafhopper, aphids, teapot thrips, thrips thrips, thrips thrips, velvetleaf yellowtail, and fruit fly and yellow leaf fly are very effective at attracting yellow to green.
In addition, Thrips palmi can attract blue or white, and onion fly can attract blue or yellow.

The pest control material of the present invention may be any one as long as the surface exhibits a color that attracts pests. For example, the substrate itself exhibits a color that attracts pests and the surface of the substrate is colored with a color that attracts pests. The ones that have been done are listed. Further, the pest control material of the present invention is not only one in which the entire surface exhibits a color that attracts pests, but within the range where the object of the present invention is achieved, part of the surface of the base material attracts pests. It may have a color.

Examples of the substrate used in the pest control material of the present invention include cloth, papers (filter paper, Kent paper, etc.), rubber, glass, plates, polymer films (polyethylene film, polypropylene film, polyethylene terephthalate film, etc.). Can be mentioned.

The pest control material of the present invention can be obtained, for example, by coating the substrate having a color whose surface attracts pests with the compound dissolved in a solvent by a method such as coating, impregnation, absorption, kneading, or the like. The compound and a coloring material having a color that attracts pests are dissolved in a solvent, and this is applied to a base material, impregnated, absorbed,
It can be manufactured by a method of supporting by a method such as kneading. Examples of the solvent used in this case include alkylbenzenes such as toluene, xylene and ethylbenzene, ketones such as acetone and methylisobutylketone, vegetable oils such as cottonseed oil, soybean oil and rapeseed oil, and mixtures thereof.

In the production of the pest control material of the present invention, additives such as a surfactant, the present compound and a stabilizer for the substrate are added to improve adhesion to the substrate and permeability. It can also promote penetration and distribution to insects.

In the pest control material of the present invention, the amount of the present compound supported on the substrate varies depending on the type of the substrate,
Generally, it is 0.0001 to 10 mg / cm ² .

The pest control material of the present invention obtained as described above can be used by installing it in a habitat of pests. When the pest control material of the present invention is used for controlling pests that damage agricultural crops such as sugar beet, cotton, flower, tea, fruit tree and mushroom, it can be used, for example, by the following method. 1) A method of covering or surrounding a part or the whole of the agricultural product with a sheet-shaped or net-shaped pest control material of the present invention. 2) A method of installing one or a plurality of flat pests or tape-shaped pest control material of the present invention according to the height of the agricultural product concerned at appropriate intervals. 3) A method of installing the pest control material of the present invention in the form of a warp, a well-drenched, or a blind in the furrows of the crop. 4) A method of installing the insect-controlling material of the present invention in the shape of a warm or a blind in the opening of a greenhouse where the agricultural product grows. 5) A method of installing one or more sheets of the pest control material of the present invention in the form of a sheet on the soil surface.

At this time, the pest control material of the present invention is usually 0.0005 to 5000 g in terms of the amount of this compound per hectare, although it varies depending on the time of application, place of application, method of application, type of pest, and degree of damage. Degree, preferably 0.0
It is used in an amount of about 05 to 500 g.
