How to deal with pesticides when they expire?

What to do if pesticides expire? **Buy back pesticides. Before I could use it properly, it turned out to be expired.

Does this still work? Expired pesticides can only be thrown away. As we all know, can these expired pesticides just be thrown away?

Naturally not! In addition to being thrown away, there are other solutions to expired pesticides!

First, pesticides are still effective even after they have expired. Most people think that once the pesticide expires, it becomes a waste product, and it has no effect, but they don't know that pesticide is a special commodity, and its shelf life is determined according to the expected control effect of green plant diseases and insect pests at normal doses. Therefore, even if the pesticide has passed the shelf life, only the dosage of the pesticide needs to be appropriately increased, and the effect of the pesticide itself can still be stimulated if the demand is appropriate.

Second, expired pesticides should not be thrown away at will. General pesticides are rich in a large number of toxic substances, which will cause obvious environmental pollution to the natural environment, and if the destruction is unreasonable, it is very easy to bring greater damage to the natural environment. Under normal circumstances, pesticide destruction needs to be solved by professional personnel, and special manpower treatment is required to avoid environmental pollution brought by pesticides to the natural environment as much as possible.

Therefore, the general public is not suitable to throw away expired pesticides when dealing with them, but should use professional treatment methods to deal with them.

Third, pay attention to the method of using pesticides. In the daily use of pesticides, farmers are easy to encounter the expiration of pesticides, which requires farmers to pay attention to the ways and means of using pesticides in the usual use of pesticides. Especially in the emergence of crops, the leaf area index of crops is relatively small, and the dosage should be reduced accordingly, so that the efficacy will not weaken or even become ineffective in the future.

In other growth and development links, you can appropriately improve the spraying of pesticides on green plants, and if the pesticide expires, you can also increase the amount of use with peace of mind, so as to ensure that the expired pesticide can also have a certain efficacy.

When using pesticides in ordinary times, farmers should also pay attention to the fact that the method of uniform spraying should be adopted, so that the liquid medicine is always connected to the pressure scale line of the brake chamber, in this pressure state, the sprayed medicinal materials can cause fine droplets, which can be evenly attached to the front and back sides of the leaves, so as to complete the best pesticide effect. Therefore, whether it is an expired pesticide or a normal pesticide, if you want to achieve the best effect, you must find the appropriate way to use it.

It can be thrown in the trash, or sent to the relevant treatment station, or it can be sprayed directly in the ground, and when disposing of it, you must pay attention to the changes produced by pesticides.

It can be diluted and then sprayed on some weeds, which can also provide some good effect and can also avoid problems.

These pesticides must be handed over to the relevant departments for destruction, which is relatively safe.

The pesticide has expired and cannot be used. Expired pesticides have not been able to kill pests and diseases, and they will have a good effect on crops, so expired pesticides are not recommended.

If the pesticide has expired, then I think the pesticide can not be used, the expired pesticide has no medicinal effect, so there is no need to use the expired pesticide again.

When pesticides are used, they have a certain shelf life, and the efficacy is best within the specified period. After all, the production of pesticides is generally chemical ingredients, microbiotics, etc., which are affected by water, light and humidity, so that the original performance will be reduced, so that there is no medicinal effect at all, and the effect on weeding and insecticide will be weakened. Generally, the retention period is about 2 years, and the longer period is 3 years.

Expired pesticides are recommended not to be used, because this may affect the growth of crops, because expired pesticides may produce some things that are not good for crops.

1. Expired pesticides can also be applied by adjusting the amount of use moderately.

In fact, pesticides are a special product, and their shelf life is based on the estimated control effect of green plant diseases, pests and diseases under all normal use levels. Many expired pesticides only need to be moderately adjusted and applied in a reasonable way, which still has the actual effect of effective insect control and disease prevention.

2. Pesticides are highly toxic and polluting, and cannot be destroyed at will.

Even if it is a specialized professional and technical personnel, it is necessary to choose unique technical measures to destroy it, and it must ensure that environmental pollution is avoided as much as possible, and the cost of destruction is relatively large. Therefore, it is not advocated to destroy all pesticides that have expired.

3. Recognize the production date and shelf life, and adjust the dosage and shelf life has not yet arrived, and apply the dosage strictly according to the specific guidance; If the shelf life has not been long after the expiration date, the dosage should be appropriately adjusted according to its medicinal strength. Due to the decrease in biological activity of some microbial pesticides after expiration, the drug power becomes weaker; However, the concentration value of some ingredient pesticides increases after expiration, and the toxicity increases. Therefore, in the application of outdated pesticides, the first use must be in accordance with the specific guidance dosage of pesticides, after 3 5 days after application, query its insecticidal results, if the actual effect is not very ideal, can be appropriately increased in most of the original dosage; If the result is still not significant after the second spraying, it is necessary to change the pesticide or replace the application of the pesticide; If the results are remarkable after application, it can be applied continuously.

It is necessary to grasp the dosage according to the development trend of crops, especially in the seedling link, the leaf area index is small, and the amount of pesticides needs to be reduced accordingly, but the spraying of pesticides is still proportioned according to the specific guidance dosage. In other links, the amount of expired pesticides can be appropriately increased.

Pesticides should be sprayed at the average value.

When spraying pesticides, the liquid medicine should be connected to each other from beginning to end on the working pressure scale net of the brake chamber, and under such heavy pressure, the sprayed medicine will cause fine particles, which can evenly adhere to the front and back of the blade. Generally, when spraying, the nozzle is placed under the crop blade, the mouth is facing up, the blade is positive, and the back can be sprayed evenly without changing the printer nozzle position. Generally, it is better to spray once, and it is not suitable to carry out several sprays at the same time, otherwise it is easy to produce fertilizer.

In fact, the expired pesticides are not all "ineffective, mildew" pesticides, but pesticides that are likely to fail to achieve the estimated actual effect according to the original application amount. Many expired pesticides can still be used after moderate dosage adjustment. And, from the perspective of environmental protection, it is obviously more cost-effective to "use" expired pesticides than to destroy them.

1. Handed over to the local environmental protection department for disposal;

Second, the pesticide submitted to the local chemical research institute or quality and technical supervision bureau for inspection, if the active ingredient of the expired pesticide has not changed, the inspection department issued a certificate, can still be sold, but in the sales process must explain to the consumer that it is an expired pesticide but the composition has not changed this situation. Of course, if the test results show that the active ingredient of the expired pesticide has been changed, it can only be sent to the environmental protection department for disposal.

For expired pesticides, the owner of the pesticide can first fill in the application form with the local environmental protection department, indicating the name and quantity of the pesticide, and then authorize the corresponding unit for processing. Personnel from the environmental protection department supervise the disposal on site, including chemical treatment and burning. The owner of the pesticide must pay a prudent pollutant treatment fee to the treatment unit when authorizing the treatment unit.

Scattered expired pesticides can be unified by pesticide manufacturers, and then uniformly treated accordingly. Pesticide dealers and farmers should not dispose of expired pesticides at will, so as not to cause undue environmental pollution. I believe that the deterioration of the rural environment in some areas in recent years has made many people begin to wake up and tease Sun

Destroying the surrounding environment is leaving behind the seeds of harm to others and oneself, and one day it will bear evil consequences that harm the world.

Expired pesticides are often seen by rural farmers. Whether it is planting crops or planting fruit trees, you need to spray pesticides several times a year, and because this side is far away from the pesticide supply and marketing cooperatives, so basically go to get it once a year, every time you will take the pesticides required for each stage of the crops, sometimes you are afraid that the pesticides are not enough, it is inevitable to take more pesticides, and if you can't use them, some will expire in the second year, for these expired pesticides, most of them are thrown away in our rural areas, because they are afraid that the pesticides will not be effective. And generally, a pack of pesticides is only a few dollars, and if you throw it away, you will throw it away, mainly because you are afraid that it will delay the growth of crops, and the gains will outweigh the losses.

In fact, after the pesticide expires, it does not mean that the pesticide can not be invalidated, but the efficacy of the pesticide label has decreased, so after the pesticide expires, as long as the dose is increased, it can also achieve the effect of pesticide control, but this dose does not mean that we can add it casually, once added too much will cause pesticide damage to cause crops to dry up or even die, so before using expired pesticides, you need to go to the local pesticide station in advance to re-inquire about the amount of pesticides, so as to avoid crop damage. Some pesticides will be less effective, and some pesticides will be open for too long, the ingredients in it will change, and it will be toxic.

Expired qualified pesticides are not equivalent to counterfeit and shoddy pesticides. Expired pesticides still have different effects depending on how long they have been expired. For example, it is not the same for someone to buy a box of qualified eight-treasure porridge with a shelf life of 24 months than to buy a box of counterfeit and shoddy eight-treasure porridge.

Fake and shoddy eight-treasure porridge cannot be drunk on the first day of delivery. And the eight-treasure porridge with a shelf life of 24 months is within the shelf life at the last second of the 24th month, and it is safe. So after the expiration date, one second, one minute, one day, can you drink it?

Does the expiration date matter a second, a minute, and a day? Of course, I'm not encouraging you to drink eight-treasure porridge outside of its expiration date. I want to use this example to illustrate that there is a different grace period after the expiration date, that is, the longer the expiration date, the longer the grace period, the shorter the expiration date, the shorter the grace period.

The shelf life of pesticides is generally two or three years, the expiration time of the pesticide still has a certain efficacy, can be used, can be achieved by increasing the concentration ratio to achieve the purpose of treating diseases and insects, this method of absorbing and decomposing the effect of treating diseases and insects is much better than littering and deep burial, littering affects the health of humans and animals, and deep burial affects groundwater resources.

Because expired pesticides can pollute the environment if they are littered, they should be managed in a unified manner and try not to let them pollute the environment.

At this time, it must be disposed of in a timely manner, and cannot be discarded at will, at this time, it can be directly handed to the retailer, or directly handed over to the industrial and commercial bureau, and then collectively destroyed.

It is best to dig a pit for expired pesticides, bury the pesticide in it and destroy it, and can no longer use such a treatment method, which is the safest, and will not harm others, nor will it let some other animals eat and endanger animal life.

Expired pesticides should not be dumped in the field, not to be poured into ponds, streams, rivers or wells, nor can they be used after increasing the concentration at will, and should be buried deep to avoid polluting the environment. In addition, the remaining liquid medicine and the wastewater used for washing the sprayer should be properly disposed of, and should not be dumped at will, and attention should be paid to the protection of the environment.

Administrative penalties confiscated with counterfeit pesticides shall be dealt with in accordance with the relevant provisions of the Administrative Punishment Law. According to the provisions of the "Administrative Punishment Law" on the confiscation of illegal property, except for items that shall be destroyed in accordance with law, illegal property confiscated in accordance with law must be publicly auctioned or disposed of in accordance with relevant state regulations.

Article 74 of the Administrative Punishment Law of the People's Republic of China: Except for items that shall be sold for destruction in accordance with law, illegal property confiscated in accordance with law must be publicly auctioned or disposed of in accordance with relevant state provisions. All fines, confiscated illegal gains, or money from the auction of confiscated illegal property must be turned over to the state treasury, and no administrative organ or individual may withhold, privately divide, or covertly divide privately in any form. Fines, confiscated unlawful gains, or funds from the auction of confiscated illegal property must not be directly or indirectly linked to the evaluation or evaluation of the administrative organ that made the administrative punishment decision and its staff.

Except for those that shall be returned or restituted in accordance with law, the financial departments shall not in any form return fines, confiscated illegal gains, or confiscated funds from the auction of illegal property to the administrative organ that made the administrative punishment decision.
