What is the difference between acute and chronic rodenticides?

According to the speed of action of rodenticide after entering the rat body, it is divided into two categories: acute rodenticide and chronic rodenticide. Acute rodenticide rodents can be lethal if they eat enough lethal bait at one time. The advantages of this type of medicine are that they act quickly and consume less food, but they are unsafe for humans and animals and are easy to cause secondary poisoning.

Chronic rodenticides, also known as slow-acting rodenticides and safety rodenticides, can be divided into the first generation of anticoagulant rodenticides, such as anti-rat sodium salt, raticide, rodenticide, etc. Another type of chronic rodenticide, called the second generation of anticoagulant rodenticide, this kind of rat poison has bromadiolone, Dalong, killing it and so on. Practice has proved that chronic anticoagulant rodenticides are relatively safe for humans and animals, and the degree of secondary poisoning caused by cats, dogs and other natural enemies is also relatively light, and it is suitable for popularization and application in rural areas.

1.Rodenticide: also known as rickle, the preparation has a rodenticide water agent, and the warning color is green.

The preparation method of poison bait is (soaking method): press 1:10:

The ratio of 190 (medicine: water: bait) is diluted with warm water first, poured into the weighed bait, stirred while adding the liquid medicine, and simmered for about 16 hours after adding the liquid medicine, stirring every few hours until the bait is evenly absorbed.

Finally, it is dried to prepare a rodenticidal bait containing active ingredients for later use. If the bait is grain, the amount of water should be increased so that the grain can absorb the liquid medicine dry, and the absorption is even.

2.Rat Killing: Also known as Rat Sniper. The drug has a slow rodenticidal effect, and dead rats are generally found on the 3rd day after administration, and the peak of death occurs on the 5th-7th day. Rat kills are mainly used to kill domestic rats.

3.Sodium salt of enemy rats: It has a strong stomach toxicity effect on rodents, good palatability, slow rodenticial effect, no severe indications in poisoned individuals, and it is not easy to introduce the vigilance of other individuals of the same kind, so that the vast majority of individuals can eat enough to kill the dose.

4.Bromadiolone: At present, the most commonly used is bromadiolone water agent, and the warning color is red.

The preparation method of poison bait is: press 1:9:

90 (medicine: water: bait) ratio, pour the medicine into the water first, stir evenly, and then slowly pour the medicine into the bait, stirring while pouring, the bait will completely absorb the potion and prepare it into a poisonous bait containing active ingredients.

Pile up the prepared poison bait for about 5 hours and dry it for later use. The poison bait is pale red in appearance.

5.Dalong: also known as bromorein and bromoraton, it should be placed in a poison bait station when used in rural areas.

Poison bait suitable for processing into or. When preparing poison bait, you can press 1:6 or 1:

10-fold dilution to water. After dilution, mix with the peeled grains, stir well, and dry before use. Press 1:

49 times on the water to kill the warehouse rats.

6.Kill it: also known as fluorramine. To control house mice, about 50 grams of poisonous bait or wax blocks per room, 4-5 grams of pests per point to prevent and control farmland pests, and 1000-1500 grams of poisonous bait or wax blocks per hectare.

Highly toxic acute rat poison has been expressly prohibited by the state from prohibiting the production, sale and use of sodium fluoroacetate, fluoroacetamide, rat poison (also known as rat life, 424), glycofluoride, rat poison silicon and arsenite acid (arsenic, white arsenic), Anto, rodent exterminator, rodent exterminator, red sea scallion, Shidinian (strychnine, carvacine) and other rodenticides. The common characteristics of this type of rodenticide are: high toxicity, strong virulence, rapid action (minutes to hours) after entering the human and animal bodies, severe poisoning symptoms, and animals are screaming; People present with epigastric discomfort, hallucinations, trance, confusion, dizziness, headache, nausea, vomiting, convulsions, and convulsions.

Mice poisoned by fluoride such as fluoroacetamide will cause poisoning and death after being swallowed by other carnivores such as cats, weasels, dogs, snakes, and birds of prey because most of the poisons are not decomposed by the stool, that is, secondary poisoning.

Will you die if you eat rodenticide.

Highly toxic acute rat poison has been expressly prohibited by the state to prohibit, sell and use sodium fluoroacetate, fluoroacetamide, rat poison (also known as rat life, 424), glycofluorine, rat poison silicon and arsenite acid (arsenic, white arsenic), Anto, rodent exterminator, rodent exterminator, red scarton, Shinian (strychnine, carcasse) and other rodenticides. The common characteristics of this type of rodenticide are: high toxicity, strong virulence, rapid action (minutes to hours) after entering the human and animal bodies, severe poisoning symptoms, and animals are screaming; The person presents with epigastric discomfort, hallucinations, trance, confusion, dizziness, headache, nausea, vomiting, convulsions, and convulsions.

Rats poisoned by fluoride such as fluoroacetamide will be poisoned to death by cats, weasels, dogs, snakes, birds of prey and other carnivores after being swallowed by other carnivores, that is, secondary poisoning.

A: The mechanism of poisoning of various rodenticides is not the same. Anticoagulant rodenticide is to inhibit prothrombin in mice, so that the blood loses its coagulation effect, causing microvascular hemorrhage and death. Organophosphate rodenticides mainly inhibit choline-ester tremor.

The effect belongs to neurotoxicity.

Dose. Chemical sterilization agent for rats is the use of rats to eat sterilization agents to cause lifelong sterility, reduce the population of pests, and reduce the harm of rodents.

<> rodenticides refer to a class of pesticides used to control rodent pests. According to the mode of action and the purpose of use, rodenticides can be divided into chemical agents, fumigants, rodent repellents, sterile agents and synergists that can improve the rodenticide effect of other agents. According to the speed of rodenticide, it can be divided into two categories: acute and chronic.

Acute rodenticides are characterized by a fast rate of action, which can be fatal after eating pests, but they are highly toxic and unsafe for humans and animals, and are prone to secondary poisoning. For example, zinc phosphide, Anto, fluoroacetyl repowonamide and so on are acute rodenticides. Chronic rodenticides are characterized by slow excretion of pesticides in rats, rodents eat several times in a row, and the pesticides accumulate to a certain dose before they can cause rat poisoning and death, which is relatively safe for humans and animals.

For example, warfarin, dichloride, ratdex, bromirene, etc. are slow-leaking rodenticides.

Rodenticides refer to a class of pesticides for the prevention and control of rodents, including direct poisoning through gastric poisoning and fumigation as nuclei or indirect control through chemical sterilization and avoidance.
