Abstract

PURPOSE:An animal parasitic ovicidal agent, consisting essentially of o- dichlorobenzene and quinomethionate and having more powerful parasitic ovicidal effect than the conventional ortho agent. CONSTITUTION:An animal parasitic ovicidal agent consisting essentially of quinomethionate expressed by the formula (chemical name; S,S-6- methylquinoxaline-2,3-diyl.dithiocarbonate) and o-dichlorobenzene. The mixing weight ratio thereof is preferably about 40-90wt% o-dichlorobenzene to about 0.1-15wt% compound expressed by the formula. An emulsion is optimum for the dosage form. Normally, various parasitic eggs, e.g. mawworm, tapeworm, liver fluke, etc., contained in excrements, etc., in a barn can be killed. The agent is more effective than the conventional ortho agent.

In the present invention, the parasitic egg preparation includes, for example, livestock such as horses, cows, pigs, chickens, goats, and sheep, as well as poultry, birds, dogs,
It is a drug that kills eggs of parasites such as roundworms, flukes, stomach worms, lungworms, liver flukes, etc. that parasitize cats and other pets. When these animals are raised, they are often infected with various parasites at each developmental stage, which causes diarrhea, bleeding, anemia, etc., and malnutrition that leads to stunted growth and death. This is a big problem for animal breeding rooms.

As the surfactant, one is selected that has good emulsion stability, does not reduce the parasitic egg effect, and has high adhesiveness. For example, as anionic compounds, carboxylates,
Quaternary ammonium salts, pyrimidiram salts, imidazolium salts, etc. are cationic such as sulfonates, sulfate ester salts, phosphate ester salts, and aminocarboxylic acid salts, imidazolium salts are zwitterionic ones. Examples include lium betaine type and carboxybetaine type. However, using only the above-mentioned ionic surfactant may sometimes lack emulsion stability in water. Specifically, metal ions such as alkali metal ions in animal feces and soil, or mixed organic substances destroy the emulsification and not only do not produce the desired effect, but also cause 0-dichlorobenzene, chinomethionate, etc. Causes local coalescence and concentration in the material to be sprayed. In particular, when the object to be sprayed is animal excrement such as chicken manure, and when this is applied to agricultural crops as fertilizer, there is also concern about secondary chemical damage to the crops. In order to avoid this, such a phenomenon can be prevented by selecting an optimal nonionic surfactant and using it in combination with the above-mentioned ionic surfactant. Examples of nonionic surfactants include polyoxyethylene alkyl ether, polyoxyethylene alkylaryl ether, formalin condensates thereof, ether ester type nonionic surfactants such as polyoxyethylene glycerin fatty acid ester, and polyoxyethylene. Examples include nitrogen-containing nonionic surfactants such as fatty acid ester type nonionic surfactants and polyoxyethylene fatty acid amide.
