"There are talented people in the jiangshan generation, each leading the way for hundreds of years" The pesticide market also conforms to this law. This nonchlorochlorinated benzamide has attracted global attention since its listing in 2008, and because of its outstanding characteristics, low dosage, high insecticidal activity and high effectiveness, it has become a new favorite in the insecticidal market in many countries. The listing of chlorantranolamide has marginalized many components of insecticides, such as methylphenidate, insect mite nitrile, indate, carnitylhydrazide, lice mite urea and so on.
Since the listing of chlorhexenamide, the insecticidal market in China has been favored by many manufacturers and farmers. Because of its outstanding prevention and control effect, many farmers have used it many times for a long time. Coupled with some small domestic manufacturers, many small bottles of drugs with good effect have been produced, but they are often irregular. The vials are filled with chlorhexabenzamide and other ingredients. Although the pesticide market has been regulated since 2018, vial drugs have gradually withdrawn from the historical stage. However, the resistance caused by its indiscriminate addition of chlorhexate benzamide has been irretrievable, resulting in the current effect of a single use being much less effective than before.
Since the resistance of chlorantranose benzamide, many old ingredient insecticides that have been dormant for more than ten years have gradually entered people's perspective and have been favored by many manufacturers and farmers. It is mainly insect mite nitrile, indica, methyl vitamin salt, carbohydrazide, lice mite urea. And in recent years, more and more registered manufacturers, a large number of influx into the market, single preparations and their compounds have become the mainstream of pesticides.
The efficacy of these five pesticides is superior or inferior, and it is not possible to generalize. Today's article will tell you about the difference between these 5 mainstream pesticides? Let everyone be able to refer to it in their future choices.
<h1>Introduction to the mechanism and characteristics of 5 mainstream insecticides</h1>
Ceratonin was developed by BASF and listed on the market in 1996. It is a new type of pyrrole insecticide that mainly inhibits the synthesis of ATP energy from pests. After poisoning the pest, it eventually dies due to the inability of the body to function properly.
Indate was developed by DuPont and went public in 1998. It is a carbamate insecticide that mainly inhibits the nerve conduction of pests. After the poisoning of the pest, the nerve conduction is irreversibly damaged, and eventually the movement is out of balance, unable to eat, paralyzed and dead.
Green worm poisoning died
A vitamin salt was developed by Merck and marketed in 1984. China's earliest listing was in 2000, developed by Jingbo Agrochemical. It is an antibiotic insecticide produced by the fermentation of "avermectin B1", which mainly destroys the structure of nerve cells and inhibits neural activity. After the pest is poisoned, the feeding is stopped immediately, and the action is paralyzed and eventually dies.
Carnohydrazide was developed by Dow Yinong and marketed in 1999. It is a growth regulator of hydrazide insects. It mainly interferes with the normal growth and development of pests, inhibits pest molting and feeding, and eventually dies.
Pedicules was developed by Syngenta and listed in 1993. It is a substitute for urea insecticides that inhibit the normal molting of pests and death.
Green insect harm
<h1>Comprehensive characterization analysis of 5 mainstream insecticides</h1>
The comprehensive characteristics of insect mite nitrile: insect mite nitrile touch killing and gastric toxicity are prominent, the internal suction effect is not strong, and it does not have egg killing activity. The rapid action is outstanding, and dead insects can be found 1 hour after taking the drug. However, the duration of effectiveness is relatively short, about 5-7 days. The insecticidal effect on older insects is greater than that of young insects. The control spectrum is wide, and the control effect on chewing pests is outstanding, such as beet nocturnal moth, twill moth, small cabbage moth, etc., and also has an effect on thrips. However, resistance is susceptible to monolithic use, and it is recommended to use it twice a season. And it is easy to cause medicinal harm in melons and cruciferous families, so use with caution.
Comprehensive characteristics of indigovirus: indicositivine has a touch killing and gastric toxicity, and does not have an assorption effect and egg killing activity. The quick-acting effect is slower than that of insect mite nitrile, which takes about 4 hours and begins to die in 1-2 days. The duration of effectiveness is relatively long, up to about 10 days. The control spectrum is wide, and it has a good control effect on lepidopteran insects. It is safer and is recommended to use 2-3 times per season.
Comprehensive characteristics of methyl salt: the gastric toxicity of methyl salt is outstanding, and it has both touch killing effect and does not have egg killing activity. The quick-acting is slower, and the insects are dead in 2-4 days. The duration of effectiveness is long, up to about 15 days. The control spectrum is wide, it is efficient against Lepidoptera and Homoptera pests, and has a certain anti-effect on red spiders. Highest level of security. However, at present, the drug resistance is serious, and it is mostly used for prevention and compounding of insecticides of other ingredients.
Comprehensive characteristics of carnitosylhydrazide: carnitylhydrazide has a strong gastric toxic effect, both touch killing effect, with egg killing activity. Slow activism, about 3 days of dead insects. The long duration of the effect will lead to the sterilization of pests, which can last up to about 15 days. Control targets are selective and are effective mainly against Lepidoptera larvae. High safety, it is recommended to use 2-3 times per season.
The comprehensive characteristics of lice mite urea: it has touch killing and gastric toxicity, has egg killing activity, and does not have systemic activity. Slow activism, about 3 days of dead insects. The duration of the effect is long, up to about 20 days. It is very effective against sucking pests and lepidoptera pests. Safe to use, often used as an oviculide.

<h1>Analysis of pesticide compound agents commonly used in the market</h1>
The above five insecticides are effective when they are first listed, but they cannot avoid the occurrence of drug resistance. In order to highlight the good prevention and control effect and win the favor of sales channels and farmers, many manufacturers register to put into production compounds, on the one hand, to increase the prevention and control effect, on the other hand, to delay drug resistance. Below I analyze the compounding machine dosage forms commonly used in the above five ingredients.
At present, there are the following kinds of popular insecticide compounds on the market, which are A-vitamin. Insect mite nitrile, acetaminum. Indigodendium, Insect mite nitrile. Indigovirus, Avi. Urea, Arvedicus. Carbohydrazide, insect mites. Carnithoylhydrazide, Avi. Insect mite nitrile, Avi. Indigo wei and so on. The market retail price is 5-10 yuan / sprayer water.
It can be seen from the above-mentioned hot-selling compound agents that although the resistance of a single preparation of methyl vitamin salt is serious, due to its outstanding characteristics and safety, the insecticide with faster compound speed can greatly reduce the rate of resistance generation and play a 1+1>2 control effect.
At present, the mainstream of the market is mainly the compound of the above 5 kinds of insecticides, and the compound dosage form mainly has the characteristics of quick-acting agent + active agent. This is the most powerful way to dominate the pesticide market. In addition to the above agents, when controlling resistant pests, it may take three to four ingredients to play a good role, it is recommended to formulate insect mite nitrile + indigodendine + methyl vitamin salt + egg killing preparation, the specific dosage is subject to the resistance level of local green insects.

Here to remind everyone, the prevention and control of green insects is mainly prevention, supplemented by treatment. Before the occurrence of insect pests, combined with the occurrence of insect pests, egg killing preparations are used for prevention in advance, reducing the base of insect sources and enhancing the control effect. And during the high incidence of pests every year, three or four agents are used alternately, which is the best way to delay drug resistance. It is not possible to use a medicine well and not to change the use of medicine, it is easy to produce resistance, and once the resistance is generated, it can be inherited, which will only increase the difficulty of prevention and control and the cost of prevention and treatment in the future.
