Is an expired pesticide more toxic or not?

Try it if it's poisonous or not, if I'm dead, please call 120 for me, I'm doing experiments for poison or not, remember my name "Idle Panic"!

Most pesticides are chemically synthesized, in fact, they generally do not affect the efficacy of pesticides after a few years without opening.

The toxicity label on all pesticide packaging is primarily for humans. Some pesticides with slightly higher toxicity will reduce the original active ingredient content after expiration, such as avermectin, with the decrease of photolysis content, the toxicity will theoretically decrease. However, some low-toxicity pesticides will become highly toxic after the active ingredient is degraded, such as cyhalothrin, which will contain more toxic fluoride and cyanide after failure.

In addition, the toxicity of pesticides is not only the toxicity of the active ingredients, but also the additives, some of which will become highly toxic substances after decomposition. In general, it is not certain that expired pesticides are more toxic! ‍‍

In fact, the insecticide can still be used after it expires, after all, it is specially prepared for insects, but the effect is weakened, and the effect is not as good as before. When using expired pesticides, it is still necessary to be as careful as before, after all, it is still toxic, and the longer the time, the worse the effect. ‍‍

It's not poisonous, and the medicinal effect for insects is definitely much smaller, but if you take it, I feel like I can still send you to heaven to play, and it will be in your soul.

During the storage period of insecticides, the insecticidal effect is gradually changing, and light, temperature and humidity, air, etc. will have a degrading effect on it, and the insecticidal effect can be guaranteed within the validity period. The expiration date of pesticides is the period for the quality of the commodity, and the effect of using it beyond the expiration date is mainly worse, and the better should not be developed; As for toxicity, as long as the original packaging is intact and the expiration date is not too large, the original toxicity will still not change much. If the original packaging is damaged, especially if there is leakage in the seal, it must be paid attention to; Especially now some pesticides with diesel, ethanol and other additives and fillers, easy to volatilize, a long time, often only the original drug, toxicity enhanced, if not carefully identified, after use is very likely to cause large-scale crop pesticide damage, heavy losses.

Therefore, expired pesticides, regardless of their toxicity, do not need to be the best choice. ‍‍

Expired pesticides can not be said to be more toxic or not poisonous, but to distinguish the inconsiderate dosage form, different additives, fillers, as well as powder, emulsifiable concentrate, colloidal agent, etc., but also involves oxidation, reduction of chemical change process, is to pay attention to the storage of pesticides environmental temperature, humidity and other conditions. In short, expired pesticides should not be used for the sake of safety (user safety, agricultural product consumer safety, crop safety) regardless of whether their virulence is lost or not. ‍‍

My dad didn't fight with anyone else when he was a child, so he went to the supermarket to buy pesticides, and when his mouth dried up, he didn't die and is now 30 years old, and he is still there. Needless to say, I'm afraid my dad will come and beat me, goodbye.

The following is a true story, I died when I was a child, so now I come to your problem with resentment! ‍‍

If it's poisonous or not, let's add it first, I think it's okay to change the label of the date. ‍‍

Expired insecticides can still be used, but the effect is not as good as before, only 50% of the effect, because after a long time, the effect will disappear, after expiration, its drug dissipates, the smell will become lighter, the insecticidal effect is not obvious, if you want to kill insects, it is recommended to buy a new insecticide.

Pesticides are chemical agents used to control pests. Including organic pesticides (organochlorine, organophosphorus, organosulfur preparations and carbamates.

pyrethroids), inorganic insecticides (inorganic arsenic, inorganic fluorine, inorganic sulfur preparations), vegetable insecticides, mineral oils.

Insecticides, microbial insecticides.

The use of pesticides has gone through several stages: the first to be discovered are natural pesticides and inorganic compounds.

But they do a single job.

1. Large dosage and short duration of effect; Organochlorine, organophosphorus and carbamate are organosynthetic insecticides, which are characterized by high or low residue efficiency, and there are many varieties of mammals.

There is a high degree of acute toxicity.

Insecticides are now mainly used to control agricultural pests and urban health pests, and they have a long history of use, large dosages and many varieties. In the twentieth century, with the rapid development of agriculture, pesticides led to a huge increase in agricultural production.

However, when using household insecticides, it should also be noted that insecticidal aerosols contain insecticidal ingredients that are harmful to the human body and have certain toxicity, especially the three-no products produced by some small factories.

Aerosols contain insecticidal ingredients that are harmful to humans far beyond international standards. In addition, some expired products due to too long or chemical reactions.

It produces greater toxicity, and if you are not careful, it is easy to endanger the health of your family.

The insecticide can continue to be used after expiration, it will still have a certain effect, but it is basically fresh in general, and it will produce more harmful impurities, which will have an impact on people and the environment.

After summer arrives, mosquitoes, flies.

Cockroaches and other pests will also become very active, and insecticides are needed to remove them. And some people will say, I didn't run out of pesticides left over from last year, can I continue to use them this year after they expire?

Generally speaking, expired insecticides will still have a certain effect, but its effect is not as good as before, basically only about half, and it continues to be used after expiration, and its insecticidal effect is not very obvious, so it is recommended to buy a new insecticide.

And if the insecticide expires, there are more harmful impurities in it, which will cause harm to people or pets, and even affect the environment.

Pesticides are still toxic after expiration, and whether they are more toxic or not toxic depends on the ingredients.

Drugs, pesticides, etc., also have a shelf life, which means that it can achieve the specified amount of the specified effect within the shelf life, they are all chemicals, when the oak is stored, even if it is sealed, it will inevitably come into contact with the outside world, and volatilization, chemical reactions, etc., resulting in the weakening of the effectiveness of the drug, and the latter increasing. Even if it is a common medicine, it may be hazardous waste when it expires.

Pesticides

Take pesticides as an example, many pesticides are not friendly to the human body, the reason why they should be used is for crops, the shelf life of pesticides is to limit the effectiveness of their dosage, pesticides have various types, urea, potassium sulfate and other pesticides will not be invalid as long as they are stored properly, and some pesticides if they expire or deteriorate, it is possible to produce toxins that harm crops and human health, such pesticides can no longer be used for fertilization.

It's not poisonous. The main reason why pesticides can kill pests is that they contain a lot of chemicals and toxic ingredients. If the insecticide continues to be used after it expires, it will not only greatly reduce the effect of killing pests, but also easily bring great threats to health if the expired insecticide has deteriorated or other chemical reactions.

During the storage period of insecticides, the insecticidal effect is gradually changing, and light, temperature and humidity scale, air, etc. will have a degrading effect on it, and the insecticidal effect can be guaranteed within the validity period. The expiration date of pesticides is the period during which the quality of the product is guaranteed, and the effect of using pesticides beyond the expiration date is mainly deterioration. Expired pesticides are still toxic, and the longer they are used, the worse the efficacy.

Changes in the toxicity of insecticides: 1. Different insecticides will have different fillers and additives, which involve the chemical reaction process of oxidation and reduction of reagents.

2. In the process of storing insecticides, the chemical reactions are changing, and the efficacy of insecticides is also changing, and light, humidity and temperature also have a degrading effect on insecticides.

3. The expiration date of pesticides is the period of product quality assurance, and the use effect will deteriorate.

4. The original packaging of the insecticide is damaged, especially if there is leakage, it needs to be paid attention to, because some insecticides now use ethanol as an additive and filler, which is easy to volatilize, and after a long time, it can cause qualitative changes, and the use of high posture may lead to crop damage.

5. If the original packaging is not damaged, the original toxicity will not change much when the shelf life is not much.

In short, as a chemical reagent, the longer the insecticide is placed, the chemical change is carried out, some of the toxicity changes will not be too large, and some will change sharply, regardless of the toxicity after expiration, it is recommended not to use it again, in order to ensure the safety of crops, the safety of consumers, and the economic safety of farmers.

Insecticides can continue to be used after they expire, and insecticides still have insecticidal effects after they expire, but the effect is relatively weak. However, the effect of insecticide is better if it has not expired, so everyone buys insecticide or use it in time and do not wait until it expires.

If you use pesticides normally, it is nothing and will not affect your health, but if you use them incorrectly, they may affect your health. If people accidentally inhale insecticides, it will affect their bodies, so it is recommended to go out after spraying insecticides indoors to avoid being affected by insecticides. Living in an insecticide environment for a long time may affect the nerves and may cause damage to the nervous system.

Although pesticides have slight toxins, they are still relatively small, and if you inhale them less, the insecticides will not affect your health. How long can you get in after spraying insecticide, about half an hour, pay attention to ventilation after spraying insecticide, and people should not stay in the room. Small children are more vulnerable, so it's best not to expose them to pesticides.

If you feel unwell after spraying insecticides, it is better to go to the hospital for a check-up**.

Insecticides can affect your health, so it's best not to use pesticides too often, whether it's the amount or the number of times you control it. If you feel dizzy and nauseous after using insecticide, it is best not to spray insecticide.

In addition, when spraying insecticides, it is best to seal the food and drink well to avoid the insecticides from contaminating the food, which will affect your health. There are also different grades of pesticides, so don't choose the ones that are too toxic, and the low-toxicity insecticides are better and less harmful. When using insecticides, they should be placed in a cool place, preferably alone, not with other things, and do not collide and squeeze casually, affecting the use of insecticides.

The insecticide can only go in after half an hour of spraying, because the insecticide can stay in the air for a while, and it is better to go in for half an hour for health reasons.
