KR810000014B1 - Process for preparing rodenticide - Google Patents

Abstract

Rodenticide having longer storage stability was prepd. Thus, warfarin or zinc phosphide granules were coated with paraffin wax in the ratio of 1: 0.1-5. Coated warfarin or zinc phosphide was then mixed with diets and recoated with paraffin wax at the ratio of 1: 0.2-2. Coagulation procedure was followed afterwards.

Description

Method of preparing the insecticide

The present invention relates to a salsaicide, which is an improvement of the composition method of the salsaicide of Patent No. 4,167. There are many ways to rescue rats, but until now, no method has been invented that can be as effective as using a pesticide. There are dozens of species being developed as salsaje, but none of them is close to perfection. Therefore, it is an urgent task to develop a killing agent with a high selection type and a good feeding rate of rats at this stage. As the fertility of rats increases exponentially, effective rescue is not possible with temporary or occasional dosing. Therefore, effective killing of rats can only be achieved by continuously administering a killing agent into the rat's passage and habitat. However, even if you do not eat the flesh, even if the rats do not avoid the killing or feeding the lethal dose can not be expected.

Rat food is omnivorous, but it tends to rot away from food that is spoiled or moldy, so it is of utmost importance that the drug is not altered. Zinc phosphate or anti-blood coagulant Walparin kills rats with only 2.5% -0.005% of its main ingredient, so most of the killing agents are formulated by mixing them with ingredients such as grains and palatable foods that rats eat well. Under one condition, after 2-3 days, deterioration or mold will occur, and the feeding rate of the insecticide will be lowered and it will not be effective.

In particular, most of the rats (mice) that predominantly in Korea inhabit the rat's den or the sewer of the land, so in order to rescue them, it is most effective to do so in the wet sewer or the ground. The situation is not getting the effect.

In particular, the composition method of the salsaicide developed by the applicant's prior patent No. 4,167 is coated by mixing the zinc phosphate particles with paraffin wax 1: 0.1-5, thereby delaying the degradation of the drug in the stomach of the rat. The purpose is to increase the feeding amount of the drug until it appears, and even when mixing with the subsidiary materials, the main ingredient is coated, so it is focused on suppressing the decomposition of the main ingredient, but it is not possible to prevent the decay and the deterioration of the subsidiary material. The weak point was that it could not be stored for a long time.

In order to correct such defects, the present invention is to prepare a finished product by mixing a salicide, a zinc zinc phosphate or a walfarin, etc. with a subsidiary ingredient in a constant ratio, and then mixed with a paraffin wax, which is a moisture resistant substance, in a ratio of 1: 0.2-2. After coating, make various shapes to be suitable for the place of administration and do so in the sewer and rat oyster, so the freshness of the acaricide can be improved for a long time. In particular, in order to administer to the sewer where the rats inhabit a lot, it is necessary to solidify the insecticide and to hang it in the space, so the above method can achieve the desired purpose.

To date, zinc phosphate is commercially available only in intermediate products, so the general consumer who has no knowledge selects the appropriate food and directly administers the mixed preparation, and the effectiveness of salsa decreases due to the inaccuracy of the main ingredient content, the selection of subsidiary materials, and the wrong mixing ratio. However, by selecting the various subsidiary materials according to the present invention, it is possible to manufacture the finished product with the correct prescription and preparation method to supply to the consumer while improving the salsa effect.

Paraffin wax used in the present invention may be used in addition to paraffin wax or vinyl resins and acrylic resins, but these materials have a tendency to avoid rats, so the feeding rate is greatly reduced, and thus the drug cannot be harvested.

Hereinafter, the present invention will be described with reference to Examples, but the present invention is not intended to be limited to the Examples, and the present invention can be modified within the scope of the claims.

Example 1

50 g of zinc phosphide was added to a solution in which 5 g of ethylene cerulose was dissolved in 100 ml of alcohol, sprayed evenly while heating, and coated zinc phosphate was cooled while cooling. Here again, 5 g of paraffin wax was added to the dissolved solution, stirred, cooled and coagulated to obtain fully coated zinc phosphide.

Example 2

The wrapper and other components were mixed to contain 1% of the coated zinc phosphide particles, paraffin wax was added thereto at a ratio of 1: 0.2, stirred, and 3 g of tablets were prepared. The tablets were again immersed in a paraffin wax solution. Coagulation yields a fully coated zinc phosphate tablet.

Example 3

It contains 0.025% of the powder of walfarin. After mixing various grains and additives, the mixture and the paraffin wax solution are mixed and stirred in a ratio of 1: 0.3 in a container of a constant size and shape. Get a flesh
