Imidacloprid or acetamiprid, which one kills faster? Which one is more thorough?

Summer is a time of high incidence of various pests and diseases. If farmers fail to kill germs and pests on crops and control pests and diseases in the field, it will easily lead to a large-scale reduction in the production of various crops grown in the field at a later stage.

In the field pest control management, we farmers generally use chemical pesticides / fungicides for control, the market sells a variety of pesticides / fungicides, there are a lot of pesticides / fungicides not only look bad, but also look good, in this regard, the vast majority of farmers often do not know the difference between them, do not know which one to choose.

Take pesticides for example. In fact, the market is common, commonly used, good use of pesticides only a few or a dozen.RAMBO insect killer supplier Although the names of some pesticides look very similar, the killing effect is similar, but they are still very different from each other, such as the strength of the drug, the efficacy of the high and low, the duration of the efficacy of the duration of time, the killing spectrum wide or narrow, the killing effect of the fast and slow, the resistance of the pests, and so on. In addition, even for two similar pesticides, there are also big differences in the main types of pests, applicable temperature conditions, applicable crops, application methods, medication methods and so on.

To summarize the enterprise in a word: the same is the same drug control of the same kind of pests, choose to pass through the different pesticides, control of the same kind of pests, we do not have the same effect; the use of pesticides are not the same, kill the same kind of pests naturally can not be the same effect. Therefore, the control of pests in the field, we can first of all teachers should fully understand the different students as well as the characteristics of the pesticides and differences, otherwise you do not have to complain about the effect of their own medicine to kill insects is not good, because you pesticides simply do not have to choose the right and use the right.

The day before yesterday's article, the small basket of agricultural technology focused on a comprehensive comparison of the four insecticides imidacloprid, thiamethoxam, thiamethoxam, furosemide differences. Today, in the small basket of agricultural technology, we give you a comparison of imidacloprid and acetamiprid two kinds of insecticides, because yesterday a farmer friend raised this question, he wanted to use this insecticide to control pests in the field, but I do not know which one of these two kinds of insecticides to choose.

The common points of imidacloprid and acetamiprid were discussed.

First common point: the characteristics of the drugs are more or less the same.

Both imidacloprid and acetamiprid are common chlorinated alkali insecticides commonly used by farmers in the market, which are fast-acting, high-efficiency, broad-spectrum, medium-toxicity and long-lasting pesticides. Both of them have strong poisoning effects of touch, stomach and different degrees of systemic effects, and kill field pests by disrupting the nervous system and paralyzing the body of the pests before the pests develop resistance to the drugs at an early stage.VITFE insect killer manufacturer They are mainly used to control aphids, whiteflies, thistle and other sucking pests on field crops (note that they can kill almost the same types of pests, but the actual killing effect on different pests is different).

The second common point is that the application techniques are generally the same.

Whether it is imidacloprid or acetamiprid, these two insecticides are mainly used to kill adult pests (can not kill the eggs), the previous use of insecticides is very good, but with the long-term use of these years and blind abuse, the field pests of these two insecticides are becoming more and more resistant to the field efficacy is getting worse and worse.

Therefore, because imidacloprid and acetamiprid are less and less effective when used alone, the agrotechnical small basket suggests that we should not use imidacloprid and acetamiprid alone (when used alone, they can be replaced by insecticides with low resistance, such as thiamethoxam, thiamethoxam and furosemide, etc.) when using them for long periods of time or when pests in the field are resistant to them.Chinese SLEEP COOL Insecticide spray It is better to use it in combination with other drugs, for example, it can be used in combination with pyrethroid drugs such as permethrin or cypermethrin, which can greatly improve and enhance the killing effect, and it can also be used in combination with egg-killing drugs such as Darbutin and louse mite urea, so as to achieve the effect of killing adult pests + killing eggs + prolonging the pest control period.

The difference between imidacloprid and acetamiprid

1. The toxicity of these two drugs is different.

Although imidacloprid and acetamiprid are both relatively low toxicity insecticides, imidacloprid is less toxic than acetamiprid.

Imidacloprid is less toxic while acetamidine is more toxic.

When it comes to safety, imidacloprid is safer than acetamiprid, at least in soil, imidacloprid is better than acetamiprid.

2. Different killing speed

Although both imidacloprid and acetamiprid are quick-acting pesticides, acetamiprid kills insects faster than imidacloprid. This is because in addition to the fact that they both have a killing effect, amidoflumidine has a stronger penetration than imidacloprid.

Imidacloprid kills insects faster, the fastest 1-2 hours after dosing on the crop in the field, we can see an obvious effect of dead insects, but not through the front need to be dosed, the back of the dead insects of the immediate effect.

The killing speed of acetamiprid is faster than imidacloprid, the fastest field crops can see obvious dead insect effect after 15-20 minutes of dosing, which can play a role in the front of the dosing, the back of the dead insect effect is immediately visible.

Therefore, when the field crop short time outbreak of a large number of pests, such as aphids, if you want to faster batch kill pests, then the use of acetamiprid effect is certainly better than imidacloprid.

3, the duration of their efficacy is not the same as the duration of the drug.

Although imidacloprid and acetamiprid are both long-lasting pesticides, imidacloprid has a longer duration than acetamiprid. Under normal circumstances.

Imidacloprid is effective for pest control for about 10 days (e.g. foliar spraying), and the longest duration of efficacy can be managed up to about 25-30 days (e.g. liquid seed dressing or soil data treatment system).

The effective period of acetamiprid is about 5-7 days (e.g. foliar spraying), while the maximum effective period of acetamiprid is about 20 days (e.g. seeding or soil treatment).

Therefore, when the main purpose is to control pests in the long term, or when pests in the early stage are not serious, and it is necessary to kill pests effectively and control pests in the long term, then imidacloprid with a longer efficacy period is more effective than acetamiprid with a shorter efficacy period.

4. Their main insecticidal mechanism is different.

Although imidacloprid and acetamiprid both have the killing mechanism of poisoning by touch and stomach, but: Imidacloprid can not only kill the pests with its poisoning mechanism, but also kill the pests with its poisoning mechanism of stomach.

Imidacloprid can not only play the role of poisoning and gastric toxicity of the insecticidal function, it also has a very strong liquid endosuction activity, which kills insects mainly by gastric toxicity and endosuction, poisoning is an auxiliary therapeutic effect.

Acetamiprid can not only play the role of contact and gastric toxicity of insecticides, it also has a very strong liquid permeability, it is mainly through the contact and penetration of insecticides.

Compared with the two, imidacloprid has better absorption and gastrotoxicity, but weaker contact and penetration, so the killing speed will be slower than amidacloprid, but the killing effect will be more thorough than amidacloprid, while amidacloprid has stronger contact and penetration, weaker gastrotoxicity and endosorption, so the killing speed will be faster than imidacloprid, but the killing effect will not be more thorough than imidacloprid.

5, the main use of the two are different

First of all, both imidacloprid and acetamiprid are few liquid spray insecticides. But because imidacloprid has strong endosorption and gastric toxicity, imidacloprid has a strong killing and penetration, it is because of the different killing mechanism of this drug, leading to imidacloprid and amidacloprid the best use of the method there is a big difference.

If one compares the use management methods of imidacloprid and acetamiprid, imidacloprid is used more often than acetamiprid. For the average business:

Imidacloprid can not only be sprayed on the leaf surface, but also washed with water. It can also be used in medicated seed dipping and medicated seed dressing as well as soil spraying for insect control. Especially in seed dressing and soil spraying for the control of underground pests, imidacloprid is definitely superior to acetamiprid, mainly due to the stronger absorption of imidacloprid and the longer duration of the decision.

Since the main advantages of acetamiprid are quick kill, contact kill and strong penetration, the best way to use acetamiprid is to spray it with liquid, but it is not suitable for seed dipping mixing and soil treatment.

Therefore, for imidacloprid and amidacloprid used alone, amidacloprid is the preferred agent for rapid foliar spraying, and amidacloprid is the preferred agent for long-term control of underground pests.

6. The efficacy and temperature of these two drugs are different.

Although imidacloprid and acetamiprid are two different insecticides whose efficacy is affected by temperature, if we compare and analyze the efficacy of imidacloprid and acetamiprid, the efficacy of imidacloprid and acetamiprid is relatively small, and the efficacy of acetamiprid is affected by temperature is relatively larger.

In general, imidacloprid and acetamiprid had better insecticidal effects in the range of 18-30 °C, but there were significant differences in the effects of high and low temperatures on the insecticidal effects.

In comparison, imidacloprid is more effective at lower temperatures, while acetamiprid is more effective at higher temperatures. Generally speaking, when the temperature is lower than 15-18 degrees, the killing effect of acetamiprid will be poorer, and imidacloprid can achieve better killing effect; but when the temperature is higher than 25-28 degrees, the killing effect of imidacloprid will be poorer, and amidacloprid can achieve more ideal killing effect at this time.

Therefore, we are reminded that these two pesticides can be used alternately in different seasons and at different temperatures. In summer, early fall and other high temperature seasons (temperature above 28 degrees Celsius) when using pesticides to control pests, we will use amitraz, which has a better killing effect under high temperature, and in early spring, late fall and other low-temperature seasons (temperature below 18 degrees Celsius) when using pesticides to control pests, we will use the low-temperature killing effect. In other seasons when the temperature is within the range of 18-28 degrees Celsius, imidacloprid or acetamiprid can be used.

7. Their primary types of pest control are different.

Although both imidacloprid and acetamiprid are highly effective pesticides for the control of sucking insects, there is a degree of difference in the specific types of pest problems that can be controlled.

In general, the insecticidal properties of imidacloprid and acetamiprid are similar (e.g. aphids, thistle, lice, cabbage moths, weevils, leafhoppers, stem borers, midges, leafhoppers, etc.), but imidacloprid does not have as wide a range of insecticides as acetamiprid, and acetamiprid kills a greater number of pests than imidacloprid.

In particular, imidacloprid is more effective than acetamiprid in controlling rice fly, while imidacloprid is more effective than imidacloprid in controlling whitefly, wheat aphid and vegetable aphid. In any case, the effectiveness of different drugs may vary greatly in different areas with different resistance. 8.

8. They are different in the types of crops they are used on.

Although both imidacloprid and acetamiprid can be used on crops in most areas, but according to the actual teaching effect of the insecticidal treatment in the field after the patient has used the drug, imidacloprid is more suitable for use on various types of crops:

Imidacloprid is more suitable for the development of various types of economic fruit crops, fruits and vegetables crops, as well as through the field crops (such as wheat, rice, corn, peanuts, potatoes, cotton, medicinal herbs, etc.) can be used, and acetamiprid is more suitable for the study of fruit trees, fruits and vegetables crops, as well as China's tobacco crops to use, but in this analysis of the two overall level of the difference is not too big, we do not need to go in-depth on this point! We don't need to learn to understand this point in depth.

In fact, in the control of aphids, in addition to imidacloprid and acetamiprid, which are two better insecticides, there is a better insecticide for aphid control. The killing speed is fast, direct and intense, but due to the strong penetration of this insecticide, it is easy to cause crop damage, and there is no special introduction in the small basket of agricultural technology. It is recommended not to use this pesticide blindly, and farmers should not use this pesticide in general.
