Acute rodenticides, also known as acute single-dose rodenticides, rodents once eat enough lethal amount of poisonous bait can be fatal. The advantage of this type of drug is the role of fast, less food consumption, but they are not safe for humans and animals, easy to cause secondary poisoning, at the same time in the process of extermination of rats before the death of the rat reflect more intense easy to cause other rats alert, so the extermination effect is not as good as chronic rodenticides. Fluoroacetic acid amine and poisonous rats, glycofluoride due to the toxicity of strong, no special antidote, it is easy to cause human and animal poisoning, the country has been expressly prohibited.
Chronic rodenticides, also known as slow-acting rodenticides, can be divided into the first generation, the second generation of anticoagulant rodenticides. The first generation of anticoagulant rodenticides, such as sodium salt, rodenticides, rodenticides, rodenticides, rodenticides, rodenticides, chloro-dichloro-rat, etc., such as to achieve the desired effect of rodenticides should be several days in a row to throw the drug. The second generation of anticoagulant rodenticides acute toxicity is relatively strong, rats eat the second, three times can be fatal, and the first generation of rodenticides resistant rats can also be killed. These drugs are bromadiolone, dalong, kill it war, sulfur enemy dragon.
2, why is chronic rodenticide better than acute rodenticide?
The advantages of chronic rodenticides are: the dosage is small, the rat does not refuse to eat, until the death of the party, so the effect of rodenticides is good, the chance of livestock poisoning is small, the poison can also be used in the special antidote (Vitamin K1) to rescue. Chronic rodenticides are in line with the habits of rats to eat, rats eat is intermittent, eat and stop eating. And chronic rodenticides most kinds of rats eat once, the toxicity is not too strong, eat no uncomfortable feeling, it can be eaten continuously for a few days, the toxicity of the accumulation of strong, the rat will die. Chronic rodenticides work slower, eat drugs for more than three days most of the rat deaths, there are no dramatic symptoms before death, so the death is still taking the poisoned bait. Therefore, when a large number of rats die, almost all the rats have eaten enough of the lethal dose of rodenticide, even if some rats no longer eat or move, but also inevitably die. There is no problem of large numbers of dead rats scaring the survivors away. Chronic rodenticides have a killing effect on many kinds of rodents, and are safer for use on a large area, with good rodenticidal effect and a large number of dead rats, which is the main weapon for rodenticides at present. Chronic rodenticides mainly refer to anticoagulant rodenticides, such as bromadiolone, dalone and so on.
3, the purchase, put rodenticides Note
(1) to have the qualification of the operation of rodenticides to buy rodenticides.
(2) To understand the composition of the rodenticides used, safe detoxification methods.
(3) Keep rodenticides out of the reach of children.
(4) In case of accidental ingestion, send it to the hospital immediately.
4, the safe use of rodenticides
Data shows that the types of poisons that lead to poisoning of the Chinese people, pesticides and rodenticides are listed as the first two, pesticides accounted for 29.22%, rodenticides accounted for 28.62%. Every year, China's pesticide use is much more than rat poison use, so proportionally, acute highly toxic rat poison is the primary factor in the poisoning death of the Chinese people.
Before 1950, acute rat poison was the main means of eliminating rats, and poisonous rat poison and other drugs were commonly used; these drugs are highly toxic, have no antidote, and have long been banned. Now usually use to anticoagulant-based chronic rodenticide, rats take the drug, the symptoms are mild, not easy to cause the same kind of alarm, and low concentration, safer for humans and animals, antidote is commonly used in clinical practice, easy to be rescued after poisoning.
So it's best not to use rat poison
