How to identify fake and inferior pesticides? How to distinguish the authenticity of pesticides?

First of all, counterfeit pesticides can be identified by labels. There are many pesticides now, and there will be manufacturers, contacts, storage conditions, production licenses, implementation standards, capacity, precautions and warning labels. If we find that the label is incomplete when buying pesticides, then we should pay attention to it at this time, because according to the "Measures for the Administration of Pesticide Labels and Instructions", it is clearly stipulated that the production of pesticides must contain the above information on the label.

For those that are not, generally speaking, they are not allowed to leave the factory, that is, non-compliant and unqualified products. <>

Check the label of this pesticide for the date of manufacture and expiration date. Generally speaking, there will be a production date when buying pesticides, and there will be a shelf life, if we buy pesticides without this shelf life, and even the shelf life is far from the same condition of pesticides, we should pay attention to this time. After all, the efficacy of pesticides and ingredients are almost the same, but the formula is different, if there is a pesticide its shelf life is one year, but there is one that can be stored for more than 7 years, then it should be noted that the difference is too large and may be a bad pesticide.

When buying pesticides, there is generally a package, and the outer packaging is checked to see if there is a certificate. Just like when we buy a car, there will be a certificate, if we buy pesticides without a certificate, this should be noted, after the product self-inspection will have a certificate. If the pesticide purchased does not have a certificate, it is likely that it does not have a production license, which should be noted.

A look at the color can also be a good way to identify counterfeit and shoddy pesticides. Usually when we buy pesticides, we will more or less observe the color of pesticides, and sometimes there will be an unpleasant smell, but if we buy some pesticides, we find that the color is not right, the smell is abnormal, then we should also pay attention to this time, if there is an obvious difference, then it may be counterfeit and shoddy pesticides.

With the rapid development of science and technology, in fact, our agriculture is developing better and better, and these are also some scientific and technological products used, especially pesticides, which have played a great role in the development of personnel. Some people will have such doubts, that is, how to identify fake and inferior pesticides? On this issue, in my personal opinion, I actually think that it can be recognized by *** or unit identification code, let's learn more about it.

1 *** Identification

I believe that everyone has a certain understanding of pesticides, we all know that if some inferior pesticides are used, this is likely to lead to corresponding problems in agricultural products, and their quality will also be seriously affected, and even reduce production, so it is very necessary to identify inferior pesticides, and our identification methods are also quite a lot, for example, you can identify through ***, each bottle of pesticide packaging actually has a ***, At this time, we only need to scan the *** on it with our mobile phone, and the name of this product can be displayed, and of course, it can also be recognized and increased.

2 Unit Identifiers

Generally, when we go to buy pesticides, if you are good at observing, you will find that the outside of each bottle of pesticides actually has a unit identification code, even if you take the same product, but the unit identification code on it is not the same.

So we in our daily life, we should also pay more attention to this aspect of the problem, for everyone, understand this aspect of the problem is of certain benefit to us, and now for everyone, when we buy pesticides, we must improve our vigilance, but also do not buy those cheap pesticides for the sake of greed, which not only does not work, but will also hurt agricultural products. The above is my summary of some of the relevant understanding of this issue, I hope that I can be of some help to you in your future study and life.

Check whether the outer packaging, inner packaging, label content, production date, batch number, etc. are complete. The shelf life of pesticides is generally 2 years.

You can look at the pesticide certificate, which is a very important standard, to buy through normal channels, don't be greedy.

Observe the outer packaging, check the pesticide registration certificate number, etc. To distinguish the authenticity of pesticides, you can observe from the outer packaging of the drug, if the packaging is damaged, the label is not tightly pasted, and the label content is blurred, then the bottle of pesticide is likely to be fake; There is also a way to judge whether this bottle of agriculture is real by checking the pesticide registration certificate number.

It can be identified by the state of the pesticide, by the taste of the pesticide, by the form of the pesticide, and by the manufacturer of the pesticide.

At this time, it can be judged according to the three certificates outside the pesticide, and it can also be judged according to the composition of the pesticide, and it can also be judged according to the efficacy or taste.

To see the certificate of pesticides, choose a formal way to buy, you can check the packaging of pesticides, you can observe the condition of pesticides, you can smell the smell of pesticides.

First look at the identification of the pesticide, then observe the color and smell, and then judge whether the pesticide is regular through the manufacturer.

The elements constituting the crime of producing counterfeit and shoddy pesticides are:

1. The subject is a natural person with full capacity for criminal responsibility;

2. Subjectively, it is directly intentional;

3. The object is the state's supervision and management system for the quality of agricultural means of production and agricultural production;

4. Objectively, it is manifested as the production of fake and shoddy pesticides.

[Legal basis].Article 147 of the Criminal Law of the People's Republic of China.

Whoever produces fake pesticides, fake veterinary drugs, or fake chemical fertilizers, or sells pesticides, veterinary drugs, fertilizers, or seeds that he knows to be fake or that has lost their effectiveness, or where producers or sellers pass off substandard pesticides, veterinary drugs, fertilizers, or seeds as qualified pesticides, veterinary drugs, or chemical fertilizers, or seeds, causing relatively large losses to the production of pesticides, veterinary drugs, or fertilizers, shall be sentenced to fixed-term imprisonment of not more than three years or short-term detention, and/or a fine of not less than 50% but not more than two times the amount of the sales; If the production suffers major losses, the sentence shall be fixed-term imprisonment of not less than three years but not more than seven years, and a fine of not less than 50% but not more than two times the sales amount; and where production suffers especially heavy losses, the sentence is to be fixed-term imprisonment of not less than seven years or life imprisonment, and a fine of not less than 50 percent but not more than two times the amount of sales or confiscation of property is to be given.

There are a total of 4 methods, which can be identified by the manufacturer, by the taste of the pesticide, by the ** of the pesticide, and by the color of the pesticide.

At this time, you can judge according to the production batch number outside the pesticide, or according to the shape or quality of the pesticide, or you can judge it by the best way, and you can also judge it according to the ratio of the pesticide.

You can check whether there is a label, check the packaging of pesticides, check the appearance of pesticides, check the composition of ingredients, and check whether there is a certificate.

Identification of pesticides: 1. Dilution method: take 100 grams of emulsion pesticides, put them in a glass bottle and add 300 grams of water.

After shaking vigorously and standing for half an hour, if the concentration of the liquid medicine is uneven, there is emulsifiable concentrate on the top, and there is sediment at the bottom, it means that the medicine has become invalid. The more emulsifiable concentrate, the worse the medicinal properties.

2. Floating method: take 1 gram of wettable powder pesticide and sprinkle it evenly on 200 ml of clear water, if it is moistened and sunk into water within 1 minute, it is an ineffective pesticide, and vice versa is an invalid pesticide.

3. Oscillation method: when the emulsion pesticide is separated from oil and water, it can be shaken with force, shake the bottle, and stand for 1 hour, if the separation layer still appears, it means that the drug has become invalid.

4. Hot dissolution method: put the emulsion pesticide with precipitate into 50 warm water together with the bottle, and after 1 hour, if the precipitate slowly dissolves, it means that the drug has not been invalidated. If the precipitate is difficult to dissolve or does not dissolve, the drug has deteriorated and failed.

5. Suspension method: take 50 grams of wettable powder pesticides, put them in a glass container, add water and stir well, and let stand for 10 minutes.

Pesticide use:

1. Powder. The powder is not easy to dissolve in water, and generally can not be sprayed with water, the low concentration powder is used for powder spraying, and the high concentration powder is used for the preparation of poisonous soil, poisonous bait, seed dressing and soil treatment. The powder is easy to use, high work efficiency, and should be used in the morning and evening when there is no wind or the wind is weak.

2. WP. It has strong hygroscopicity and can be dispersed or suspended in water after adding water. It can be used for spraying, poison bait and soil treatment.

3. Soluble powder (aqueous solvent). It can be sprayed or splashed directly with water.

4. Emulsion (also known as emulsifiable concentrate). The emulsion is an emulsion after adding water, which can be used for spraying, splashing, seed dressing, soaking, poisoning soil, coating stems, etc.

5. Ultra-low volume preparation (oil agent). It is a direct spray agent, and it is a special supporting pesticide for ultra-low volume spray, and water cannot be added when used.

6. Granules and microparticles. It is a pesticide dosage form made of pesticide raw materials and fillers into granules, which is not easy to produce pesticide damage. It is mainly used for heartleaf irrigation, sprinkling, point application, seed dressing, furrow application, etc.

7. Sustained-release agents. When using pesticides, they are released slowly, which can effectively prolong the effective period, so the residual effect period is prolonged, and the pollution and toxicity are reduced, and the usage is generally the same as that of granules.

8. Tobacco agent. Smoke agent is a fine powder or ingot made of pesticides, fuels, oxidants, accelerants, etc. This dosage form pesticide is vaporized by heat, and then condensed into solid particles in the air to form smoke, which is mainly used to control pests and diseases in forests, facility agriculture and warehouse pests.

Pesticides are an indispensable tool for farmers, and the use of pesticides is inseparable from the use of pests or weeding in crops every year, but there are also some bad businesses that will make fake pesticides, so how to distinguish between real and fake pesticides has become a big problem, let's take a look at it.

1.Look at the active ingredients of pesticides where there is a Chinese generic name of pesticides must use the Chinese generic name to register, only some imported pesticides do not have a suitable Chinese name, with English generic name, the active ingredient of the pesticide can be found in the pesticide registration announcement of the drug testing institute.

2.Look at the manufacturer and contact address, the general regular pesticide manufacturer will be marked on the product with a very detailed manufacturer address, contact ** and other information, if the purchased pesticide does not have these detailed information, then the pesticide product is an irregular product. Moreover, the product packaging of regular manufacturers is also relatively rigorous, and the packaging of fake and shoddy products is not agreed, and the sealing is not strict.

3.There are some physical methods to identify pesticides for powders.

If it is a regular product, the powder is fine and smooth, smelly, can be easily sprayed, and if it is a wettable powder, it can be evenly suspended in water. However, the fake pesticide particles are not smooth, the odor is small or no, and the inferior wettable powder is difficult to dissolve or precipitate after adding water.

For emulsifiable pesticides.

Dilution method. After the regular pesticide is diluted with water, there is no oil slick on the surface of the qualified pesticide and no precipitation under the bottom of the water, otherwise it is an inferior pesticide.

Oscillation method. **After observing whether there is delamination in the bottle, if it has been stratified, and then continue to shake vigorously and evenly, if it is still stratified after 1 hour of station, it means that it is a fake and shoddy pesticide.

Granular pesticides.

Generally, the qualified products have uniform particles, have a great smell, and are not easy to change color when placed in water.

Aqueous pesticides. Observe the inside of the product, generally the qualified product does not precipitate, and it will be a uniform liquid after dilution, but there is precipitation inside the fake and shoddy product, and it will be stratified after dilution.

First of all, it can be judged according to the name of the pesticide, the standard certificate number or the registration certificate number of the pesticide, and then it can also be judged according to the active ingredients of the pesticide and the instructions and precautions for the use of the pesticide.

Fake pesticides can be identified by using the method of water agent, and generally speaking, pouring fake pesticides into clean water will make the water turbid.

You can check the composition of pesticides, you can check the marking tape of pesticides, you can check the certificate of conformity of pesticides, you can check the label of pesticides, and you can check the form of pesticides.

1. Pesticide name: The product name on the label must indicate the generic name of the pesticide, including the Chinese generic name and the English generic name, as well as the percentage content and dosage form, and the imported pesticide must have a trade name. 2. Check the "three certificates":

"Three certificates" is the product standard certificate number, production license approval certificate number and pesticide registration certificate number of the product, no three certificates or three certificates are incomplete is unqualified pesticides. 3. Pesticide active ingredients, content and weight: pesticide ingredients, content and weight that do not match the label can be identified as fake and shoddy pesticides.

Socio-economic development is getting faster and faster, farmers' economic income is getting higher and higher, many people choose the use of pesticides in order to increase yield, in fact, this is understandable, because we all know that pesticides can help us better solve some problems, but we need to pay attention to the fact that for some fake and shoddy pesticides, we must learn to distinguish.

When purchasing pesticides, we must shop around, go to the clinic with a professional qualification certificate to buy, so that we can protect everyone's legitimate rights and interests faster, and everyone is expected to know this.

We all know that the types of pesticides are very many, the relevant ingredients and their ingredients are also very different, in order to avoid the purchase of substandard pesticides, we must go to the professional pesticide store to buy, so that we can protect our legitimate rights and interests faster, at the same time, for some popular trade names or marked with classic words, we must carefully identify it, because many illegal businessmen are all using this kind of way to make a profit.

Generally speaking, there is no need to buy pesticides without labels and incomplete labels, because we all know that the sales specifications of pesticides are very strict.

We all know that pesticides and other products have a commonality, that is, they have a very strict manufacturing date and expiration date, we must carefully check before buying pesticides, the expiration date, in case of the purchase of pesticides with potential quality and safety hazards, everyone is expected to know this, at the same time, the use of pesticides must also be strictly according to the instructions for use before the first quarrel.
