Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a molded article for controlling and controlling pests, which comprises fenobcarb or an active compound, or fenobcarb and pyriproxyfen, and uses thereof.

[0002]

BACKGROUND OF THE INVENTION Insecticidally active compounds such as organic phosphorus compounds such as dichlorvos, diazinon and tetrachlorovinphos, carbamate compounds such as propoxer and carbaryl, and pyrethroid compounds such as permethrin and cyfluthrin. , Kneaded in resin, etc., or impregnated / applied to a porous body, etc. to form a collar, medal, etc.
Methods used for control are known. However, when a pyrethroid compound is used as the active ingredient compound,
Although safety is relatively high, it is difficult to obtain sufficient performance in terms of drug activity (Sanitary Animal Vol. 45, No.
2, P121-128, 1994), when an organophosphorus compound is used as an active ingredient compound, it exerts an adverse effect such as reduced physical strength and weakness on an animal, particularly a cat, wearing a molded article such as a collar, although the efficacy is excellent. Is recognized, which is not preferable for safety.
Carbamate compounds such as propoxer and carbaryl are
It is characterized by relatively high efficacy and safety, but many of them are solid at the actual use temperature (about 20 to 35 ° C) and migrate to the surface of the molded product during storage, forming a powder. Due to bloom (or bleed),
And a problem in appearance.

[0003]

Under such circumstances, the present inventors have made intensive studies on a molded article for extermination and control in which an active compound excellent in efficacy and safety can be more efficiently utilized. As a result of the continuation, the molded product using fenobcarb (o- (sec-butyl) phenyl N-methylcarbamate) as the active compound is liquid even when the fenobcarb is transferred to the surface of the molded product, and the active compound is effectively used. The present invention was found to be extremely effective and safe, and the present invention was achieved. In addition, in the present invention, in addition to fenobcarb as an active compound, the juvenile hormone-like compound pyriproxyfen (4-phenoxyphenyl 2- (2-pyridyloxy) propyl ether) having a hatching inhibitory effect is used in combination with the active compound, so that the efficacy is improved. Further long-term sustainability is possible, and the marketability is dramatically improved. That is, the present invention provides fenobcarb as an active compound,
Alternatively, the present invention relates to a molded article for controlling and controlling pests, which comprises fenobcarb and pyriproxyfen, and uses thereof.

The amount of the active compound contained in the molded article may vary depending on the type of the resin used, the use of the molded article, etc., but the amount of fenobcarb per 100 parts by weight of the resin is 0.01 to 20.
0 parts by weight, more preferably 0.1 to 100 parts by weight, still more preferably 1 to 50 parts by weight. Pyriproxyfen is used in an amount of 0.01 to 50 parts by weight, more preferably 0.1 to 30 parts by weight, and still more preferably 0.1 to 10 parts by weight, per 100 parts by weight of the resin.
Parts by weight. When fenobcarb and pyriproxyfen are used in combination, or when another active ingredient compound is further used, the total amount of the active ingredient compound is 0.01 to 200 parts by weight, more preferably 0.1 to 200 parts by weight, per 100 parts by weight of the resin. It is desirable to adjust the amount to be 100 parts by weight, more preferably 1 to 50 parts by weight.

Various plasticizers and softeners can be added to the molded article of the present invention in order to improve its performance.
The plasticizer and the softener to be used are appropriately selected depending on the type of the resin to be used and the compatibility with the resin. Examples of the plasticizer include phthalic acid esters such as dioctyl phthalate, diisodecyl phthalate, and diisoundecyl phthalate. , Trioctyl trimellitate, trimellitic acid esters such as tri-2-ethylhexyl trimellitate, tridecyl trimellitate, aliphatic 2 such as dioctyl adipate, diisononyl adipate, diisodecyl adipate, dioctyl azelate, dioctyl sebacate, etc.

For example, phenol-based, phosphorus-based antioxidants, ultraviolet absorbers, light stabilizers, Antioxidants, epoxy compounds such as bisphenol A diglycidyl ether and the like can be mentioned. Further, fenobcarb, which is an active compound, is unstable in the presence of a metal or under a high pH value, that is, under so-called alkalinity. Therefore, it is preferable to select a stabilizer so that the active compound is stable. The molded article of the present invention is usually a resin,
It can be produced in the same manner as in the case of molding rubber. For example, a resin and an active compound, and other compounding agents are usually mixed and dispersed at 20 to 140 ° C. in advance to prepare a uniform composition, or by adding an active compound to a plasticized resin and mixing. A composition is prepared, and the composition is subjected to extrusion molding, injection molding, blow molding, vacuum molding, air pressure molding, casting molding, press molding, calender molding, roll molding, etc. at an appropriate temperature usually in the range of 70 to 300 ° C. And is obtained by molding by a generally known processing method. Alternatively, it can also be produced by preparing a porous base material such as polyurethane in advance and then impregnating or applying an active ingredient compound or other compound.

The molded article for controlling and controlling pests of the present invention can be used in various shapes and various applications. For example,
