Description

Raticide, preparation method and putting method thereof

Technical Field

The invention belongs to the technical field of biological medicines, and particularly relates to a raticide, and a preparation method and a feeding method thereof.

Background

Mice not only have certain harm to vegetables, fruit trees and crops, but also infect various diseases, and are natural hosts of more than 10 epidemic diseases such as plague, pseudotuberculosis, rabies, encephalitis, brucellosis, leptospirosis, melioidosis and the like, so that the deratization is particularly important.

The prior diphacinone sodium salt deratization rice has the following defects:

1. after the human body is ingested by mistake, the diphacinone is poisoned by sodium salt, the incubation period is 1 to 3 days, but people with poor immunity can get ill after 2 to 3 hours. The symptoms of poisoning are nausea, inappetence, arthralgia and the like, and extensive bleeding occurs in 3 to 7 days, such as epistaxis, gingival bleeding, subcutaneous bleeding and the like.

2. Poisoning can be caused when livestock and poultry eat the feed by mistake, and mild symptoms are as follows: after the reduction of food intake, the patient does not eat at all, has depressed spirit, digs a pit, is prone to lie, bends the back and contracts the abdomen, is not stable to walk, then breathes quickly, pupils are contracted, the patient stands unstably, two forelimbs kneel the ground, hind limbs are straight, diarrhea is caused, excrement is thick soy sauce porridge, some contain bright red blood, purple patches appear on the skin, bright red blood is not cut off from the corners of the mouth and nostrils, and conjunctiva is pale. After the treatment, blood continuously flows outwards from the injection needle hole, and the bleeding cannot be stopped even after the compression for l-2 min. The course of disease is 3-7 days, and the patient is easy to die if not cured in time. Severe disease: the pig farm is characterized in that the pig farm is breathed suddenly at the beginning, the pig farm is unstable in walking, even rushes backwards, turns around, falls down continuously, climbs up continuously and falls down continuously, meanwhile, the breathing becomes difficult, the pig farm is breathed by opening mouth, fresh red blood flows out from corners of mouth and nostrils, so that the ground of the pig farm is blood everywhere and is difficult to solidify, and finally, the pig farm inclines to one side and swings to walk and fall down. Death occurs from hours to tens of hours.

3. When the soil conditioner is thrown outdoors, the soil conditioner can not achieve rapid natural degradation, and diphacinone sodium salt can remain in soil along with the time when the soil conditioner is thrown on soil to bring inevitable pollution to the environment.

4. The killing effect of the mice is long, the mice have a 3-day incubation period after taking the medicine, and die in 4-6 days; the whole range of mice can be killed to achieve the ideal effect after about one month.

Comparative example 1

Compared with example 4, the comparative example lacks the corresponding microwave treatment step, and the rest steps are the same, so that the corresponding raticide is prepared.

Typical engineering case

The following engineering cases are based on the following criteria for judging the use effect: before use, the feces of the mouse, the footprint of the mouse, the mouse path of the mouse and the commodities bitten by the mouse can be seen obviously, and the smell of the mouse is seen. The above conditions all disappeared after use.

The following engineering cases are selected from a small supermarket in Guangzhou city, wherein the supermarket mainly has the operation range: daily use miscellaneous goods, miscellaneous cereals, and snack products.

The major operating ranges of a medium-sized supermarket in Guangzhou city are as follows: daily sundries, snack products, coarse cereals, vegetables, fruits and fresh meat.

Selecting the reasons of the supermarket: compared with mice in the field and in restaurants, the mice in the supermarket have more varieties and large density, the food in the supermarket has more varieties and large selection space, the selection of the food is more critical, and the mouse killing difficulty is higher in comparison with other places.

The rat poison used in the following engineering examples 1 was prepared as in example 4.

Engineering case 1

Density survey before deratization of a certain small supermarket in Guangzhou city: 87 pieces of full supermarket footmark powder are distributed from 7 months and 7 days in 2020 to 17 months in 2020, and the rooms 3 of the warehouse and the place of business are checked. The density of indoor mice is 18.0%, the positive rate of indoor mice is 29.0%, and the area of the Jiaxing supermarket is 100 square;

putting a small supermarket in Guangzhou city: constructing in 18 days 7 and 7 months in 2020, throwing the top of a ceiling at a distance of 30m at a throwing point with the throwing amount of each point being 200g, throwing the ceiling on a place with mice and mouse traces by taking a key point on the ground, and throwing 300g of the ceiling at each point to totally 20 throwing points;

the mouse killing check of a certain small supermarket in Guangzhou city: in 7 days 8 months in 2020, 20 feeding points are checked in a supermarket, the food stealing rate is 97%, the palatability is very good, and the density of the mouse is measured to be 0.0% by adopting footprint powder and the indoor mouse footprint is measured to be 0.0%. The deratization effect of 99 percent is achieved.

Engineering case 2

Density survey before deratization of a certain medium-sized supermarket in Guangzhou city: the total area of the warehouse and the operation place is 400 flat meters by using 317 pieces of the foot print powder in the supermarket from 7 month to 20 days in 2020 to 23 months in 2020, the density of the indoor mice is 21.0 percent, and the positive rate of the indoor mice is 32 percent.

Putting a certain medium-sized supermarket in Guangzhou city: the top of the ceiling is thrown by distance in 24 days 7 and 7 in 2020, 40m is a throwing point, and the throwing amount of each point is 300 g. The ground is mainly put in the place where the mouse is absent and has mouse traces, and 250g of the ground is put in each point. A total of 40 delivery points;

after rat killing, a certain medium-sized supermarket in Guangzhou city is checked: 8-13 days in 2020, 40 feeding points are checked in a supermarket, the food stealing rate is 96%, the palatability is very good, and the density of the mice is 0.0% and the indoor mouse track is 0.0% by adopting footprint powder, so that the mouse killing effect of 99% is achieved.

Contrast engineering

Subject: a certain supermarket in Guangzhou city, which has the main operation range: daily miscellaneous goods, coarse cereals, snack products, vegetables, meat, seafood; the rodenticide prepared in comparative example 1 was used.

Density survey before rat eradication in the supermarket: 500 pieces of foot print powder are distributed in a full supermarket from 10 days in 5 months in 2020 to 20 days in 5 months in 2020, 5 rooms of a warehouse and a place of business are checked, the density of indoor rats is 16.7%, the positive rate of indoor rats is 28.0%, and the area of a century Hualian supermarket is 1000 square;

the supermarket is put in: 21 days of construction in 5 months in 2020, the top of the ceiling is thrown at a distance of 10m, the throwing amount of each point is 400g, the ground is thrown at a place where mice are absent and have mouse traces, 400g is thrown at each point, and 60 throwing points are counted.

The supermarket is checked after deratization: after 21 days 6 months in 2020, 60 feeding points are checked in a supermarket, the food stealing rate is 7%, the palatability is poor, the density of the rats is 16% by adopting footprint powder, the indoor rat concentration is 28.0%, and the ideal rat killing effect is not achieved.

The analysis reason is as follows: vitamin D3 was not treated with microwave, so vitamin D3 stayed on the surface of the rice husk, while mice only eaten the rice grains inside the rice, and mice did not actually eat vitamin D3, so the effect of killing mice could not be achieved.

Finally, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
