Pesticide Insecticide Chlorfenapyr
What is chlorfenapyr?
Insecticide chlorfennitrile is an organic matter, Cas 122453-73-0, white solid, is a new pyrrole compound, acting on the mitochondria of cells in insects, acting through multifunctional oxidases in insects, mainly inhibiting the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). Adenosine triphosphate stores the energy necessary for cells to maintain their vital functions. The drug has gastric poison and contact effect. It has strong permeability on the foliar surface, has a certain systemic effect, and has the characteristics of wide insecticidal spectrum, high prevention effect, long lasting effect and safety. Resistant pests can be controlled.
The insecticide chlorfennitrile belongs to aryl pyrrole compounds, which have gastric toxicity and certain contact effect and systemic activity on pests; It is an insecticide, acaricidal and nematicide agent successfully developed on the basis of dioxapyrromycin isolated from the metabolites of Streptomyces fungi. It has excellent control effect against drill borer, suction mouthparts pests and pest mites, and its effective period is medium, and its insecticidal mechanism is to block the oxidative phosphorylation of mitochondria.
Inpronile Chemical Properties
The insecticide chlorfennitrile is pure white solid. m.p.91~92 °C (100~101 °C), soluble in acetone, ether, dimethyl sulfoxide, tetrahydrofuran, acetonitrile, alcohol and other organic solvents, insoluble in water.
Dosage form 10% suspension, 30% chlorfenapyr
Physical and chemical properties and mechanism of action of chlorfenapyr
Physical and chemical properties: pure product is white or off-white oily powder, melting point: 100~101 °C, its original drug content ≥98%, soluble in acetone, ether, dimethyl sulfoxide, tetrahydrofuran, acetonitrile, alcohol, toluene, xylene and other organic solvents, insoluble in water.
Mechanism of action: Insectetile is an insecticide precursor, which itself has no toxic killing effect on insects. After insects feed or come into contact with chlorfenapyr, it is transformed into specific insecticidal active compounds under the action of multifunctional oxidases, which target mitochondria in insect somatic cells. The cell synthesis stops the vital function due to lack of energy, and the pest activity weakens after spraying, spots appear, color changes, activity stops, coma, paralysis, and eventually leads to death.
The main dosage forms are: suspension agent (70), suspension emulsion (4), microemulsion (7), water dispersible granules (1), water emulsion (2), wettable powder (1). Another component in the compound is: indanoxurand, tick miteurea, avermectin, pyridoxin, methylaminoavermectin benzoate, fenhydrazide, butethylurea, polycidalin, bifenthrin, pyriprofen, imidacloprid, methichydrazide, ivermectin.
Use of chlorfenapyr
1. Insecticide mite nitrile insecticide broad-spectrum, wide range of application can be used in vegetables, fruit trees, field crops to control lepidoptera, homoptera and other types of pests, such as diamondback moth, cabbage green worm, beet night moth, twill night moth, vegetable borer, vegetable aphid, spotted diving fly, thrips and other vegetable pests, especially the adult control effect of lepidoptera pests is very good.
2. Insecticide mite action mode Insecticide mite has gastric poison and contact effect on pests, has strong permeability on the foliage, has a certain systemic effect, and has the characteristics of wide insecticidal spectrum, high prevention effect, long lasting effect and safety. The insecticidal speed is fast, the permeability is strong, and the insecticidal is relatively thorough. (It can kill pests within 1 hour after spraying, and the prevention effect on the day reaches more than 85%)
3. Insecticide chlorfenitrile has high resistance to pest control, especially for pests and mites that are resistant to insecticides such as organophosphorus, carbamate, and methrin, and have a good effect.
Do not use medicine in high temperature time, flowering period, seedling stage, easy to produce drug damage.
Watermelon, zucchini, bitter melon, melon, melon, winter melon, pumpkin, hanging melon, loofah and other melon crops are sensitive to chlorfenapyr, and are prone to drug damage problems after use.
Cruciferous crops (cabbage, radish, rape, kale and other crops) are used before 10 leaves, which are prone to drug damage, do not use.
Use each vegetable up to twice or you may develop resistance.
Note: When the insecticide mite is harmed, it is generally acute (symptoms of drug damage will be shown within 24 hours after spraying).
If there is drug damage, it is necessary to use brassinolide + alginic acid or amino acid foliar fertilizer in time to alleviate it.
When the young larval stage or the insect population density is low, use 10% suspension, 30 ml or 30% chlorfenonitrile per mu, specialize in 30 ml/mu, when the insect age is high or the insect population density is large, use 40-50 ml per mu, add water spray. Each stubble can be sprayed up to 2 times, with an interval of about 10 days
Tips for using chlorfenapyr
1 Melon crops are prone to drug damage and are not recommended. If you don't know how to distinguish, it is recommended that you grow friends as long as you bring melon vegetables, including zucchini. In addition, the seedling stage of cruciferous vegetables is not recommended to use chlorfenapyr, such as cabbage.
2 chlorfenapyr in the actual use, to remember that the amount is not enough, really not dead insects, and pests to its resistance in recent years is also very high, so everyone at least according to the standards I said above to use, these are the results of practice.
3 Pests are very resistant to chlorfenapyr, how easy is it? According to production practice, the effect will be significantly reduced after using it up to two times, so be sure to rotate or compound other ingredient sprays.
4 Insectitrile only kills adult insects and has no effect of killing eggs, so its effective period is not long, and the second wave of pests will occur in about a week during the high incidence period of pests. Therefore, in actual use, it is recommended to use with pyripropyl ether, lice mite urea to kill eggs.
5 For the use time of chlorfennir this insecticide, it is recommended to use in the high incidence period, can quickly eliminate pests, if prevented, you can choose lower cost methyl salt, in addition, in the high incidence period of the drug must be matched with ovicide, so that the effective period will be longer.
How to use chlorfenapyr
Insectitrile has a certain egg-killing effect, combined with the prediction and forecasting of pests, it is recommended that spray at the peak of the birth and hatching of pests, or the peak of egg hatching, can play a good control effect.
Since chlorfenapyr has good local conductivity in plants, it can penetrate and conduct from one side of the leaf to the other, so the same effect can be obtained on the back of the leaf where the pest feeds.
The efficacy is 90-100% within 1-3 days after the drug, and the efficacy can still be stable at 90% 15 days after the drug, and the recommended mu dosage is 30-40 ml, and the safety interval is 15-20 days.
General antagonistic pests such as diamondback moths, night moths with 30 ml per mu, that is, 1 stick (10 ml) with 1 bucket of water (10-12 kg of water), conventional spray, for the elderly insects should increase the amount.
Features of chlorfenapyr
Wide spectrum of insecticide: Insecticidal nitrile can not only control diamondback moth, vegetable borer, beet moth, spotted loon fly, twill night moth, thrips, vegetable aphid, cabbage green worm and other vegetable pests, but also control two-point leaf mites, grape leafhoppers, apple red spiders and other pest mites.
Good fast-acting: chlorfenapyr has good permeability and systemic conductivity, can kill pests within 1 hour after application, reach the peak of dead insects in 24 hours, and the prevention efficacy of the day reaches more than 95%.
Good mixability: chlorfenapyr can be mixed with methyl salt, avermectin, indanoxurin, lice mite urea, ethyl polyfungicide, methicide and other insecticides, the synergistic effect is obvious, not only expanding the insecticidal spectrum, but also significantly improving the efficacy.
No cross-resistance: chlorfenapyr is a new type of pyrrole insecticide, and the mainstream insecticides on the market have no cross-resistance, in the case of poor control of other agents, chlorfenapyr can be selected for control, the effect is outstanding.
Insectapyr has the dual effect of gastric poison and contact killing of pests, and the permeability on the leaf surface is also relatively strong, and has a certain systemic effect, and also has a wide spectrum of insecticide, high prevention effect, long durability, safety and other characteristics. The insecticidal speed is fast, the permeability is strong, and the insecticidal is relatively thorough. (Pests can be killed within 1 hour after spraying, and the prevention effectiveness of the day reaches more than 85%).
Insectitrile has high efficacy against pests, especially pests and mites that are resistant to insecticides such as organophosphorus, carbamate, and methrin, and the effect is very good.
Features of chlorfennir preparations
First, in addition to the wide spectrum of insecticide, after years of experiments and practical applications in Datian, it has shown that it has excellent control effect on more than 70 kinds of pests in Lepidoptera, Homoptera, Coleoptera and other orders, especially for vegetable resistant pests such as diamondback moth, sugar beet moth, striated night moth, American spotted diving fly, bean borer, thrips, red spider spider and other special effects.
Second, in addition to biomimetic pesticides, low toxicity, fast insecticidal speed, 1 hour of use can kill pests, the same day prevention effect is more than 85%.
Third, the mechanism of action of breaking resistance, eliminating exhaustion, is different from the mechanism of action of other insecticides, there is no cross-resistance, and pests with serious resistance are equally efficient. In particular, it has a good effect on organophosphorus, carbamate, methrin, chitin synthesis inhibitor pests and mites that are resistant to insecticides.
Fourth, the effective period is particularly long, which can be controlled for 15-20 days in the control of resistant pests, and the residual effective period of red spider control is as long as 35 days, which can completely relieve the labor of vegetable farmers "three days and one medicine".
Fifth, the scope of application is wide, can be used for vegetables, fruit trees, ornamental plants, etc., can be widely used to control cotton, vegetables, citrus, grapes and soybeans and other crops pests and mites, the efficacy is 4-16 times higher than the conventional agents such as methocarb and acetylmethamidophos. It can also be used to control termites.
Sixth, strong permeability, foliar spray, effective ingredients can penetrate to the back of the leaf, insecticidal more thorough.
Seventh, environmentally friendly products, except for naturally screened pyrrole substances, are very safe for humans and livestock. Especially suitable for export products, high quality products.
Eighth, after nearly two years of demonstration and promotion, major cities across the country have selected bromide as the preferred pesticide for pollution-free vegetables.
Ninth, although the investment in one drug is high, due to the wide spectrum of insecticide, thorough control and long control time, the cumulative cost per mu is still more cost-effective than using other pesticides.
Use of chlorfenapyr
The insecticide chlorfennitrile is a new structure of pyrrole insecticide and acaricide. Excellent protection against borer, stinging and chewing pests and mites. More effective than cypermethrin and cyhalothrin, its dicoid-killing activity is stronger than dicofol and tricyclic tin.
The insecticide chlorfennitrile has broad-spectrum insecticides and acaricides; It has both gastric poison and contact effect; No cross-resistance to other insecticides; Moderate residual activity on crops; Selective systemic activity in nutrient solution absorbed through the root system; Moderate oral toxicity to mammals and low percutaneous toxicity; Low effective application (100 g active ingredient/hm2). Its remarkable insecticidal and acaricidal activity and unique chemical structure have been widely valued and concerned.
Mixing of chlorfenapyr
1 chlorfenonitrile + methyl salt compound
After the combination of chlorfennir and methyl salt, the insecticidal broad-spectrum can control thrips, tsubaki, jumping beetle, red spider, heartworm, corn borer, cabbage and other pests on vegetables, fields, fruit trees and other crops.
Moreover, after the mixture of chlorfenapyr and methyl salt, the effective period of the agent is also long, which can effectively reduce the number of times the agent is used, thereby reducing the cost of medicine for farmers.
The best time to use medicine is in the 1-3 instar of the pest, when the pest damage in the field is about 3%, and the temperature is controlled at about 20-30 degrees, when the drug effect is the best.
02 Chlorfenonitrile + indenoxuran mixed
After mixing chlorfenapyr and indanoxid, it can not only quickly kill pests (pests will stop eating immediately after contact with the agent and die within 3-4 days), but also have a longer duration of the effect and are relatively safe for crops.
After the mixture of chlorfenapyr and indanoxida, it can be used to control lepidopteran pests, such as cotton bollworm, cabbage worm of cruciferous crops, beet moth, diamondback moth, etc., especially the effect of anti-noctuin moth is remarkable.
However, when these two agents are mixed, the effect on the egg is not good. If you want to kill eggs and adults, you can use them with lice mite ureas, so that you can achieve the purpose of killing eggs and insects.
The best period of drug use is in the middle and late stages of crop growth, when the pest age is large or the pest is mixed with 2nd, 3rd and 4th generations, the drug effect is better.
03 chlorfenonitrile + avermectin complex
Abamectin and chlorfennitrile have obvious synergies after mixing, and have good control effects on highly resistant thrips, green worms, beet moths, leek maggots, leaf curly borers, drill borers (dimorphic borer, trichemical borer), and striated noctuis moth.
The best period of use is in the middle and late stages of crop growth, and the effect is better when the daytime temperature is low. (At temperatures below 22 degrees, avermectin has higher insecticidal activity).
04 Chlorfenapyr + other insecticides are mixed
Chlorfenapyr can also be mixed with thiamethoxam, bifenthrin, chlorhydrazide, etc., to control thrips, diamondback moth and other pests.
Comparison with other drugs: chlorfenonitrile is mainly used to control lepidopteran pests, but in addition to chlorfenapyr, tick mite urea and indancarb also have good control effects against lepidopteran pests.
Comparison of the advantages and disadvantages of chlorfenapyr, indanoxuran and lice mite urea
Insecticide chlorfenapyrr: is a new pyrrole compound. It acts on the mitochondria of cells in the insect body and acts through the multifunctional oxidase enzyme in the insect, mainly inhibiting the conversion of the enzyme.
Insecticide indanazuranda: is a highly effective umdiazine insecticide. It incapacitates nerve cells by blocking sodium channels within insect nerve cells. This causes pests to become dysfunctional, unable to eat, paralyzed and eventually die.
Insecticide chlorhydrazide: is a new non-steroidal insect growth regulator, is the latest research and development of insect hormone insecticide. It has an agonistic effect on the pest ecdyhormone receptor, can accelerate the abnormal molting of pests, and inhibit feeding, resulting in pest physiological disorders, starvation and death.
Insecticide Lice Mite Urea: The latest generation of alternative urea insecticides. It is a benzoylurea insecticide that kills pests by acting on insect larvae and stopping the peeling process.
Insecticide methylaminoavermectin benzoate (methyl salt): often referred to as "methyl salt" in the industry, is a new type of highly effective semi-synthetic antibiotic insecticide synthesized from the fermented product avermectin B1.
One. Comparison of insecticidal methods
Inchlornir: has gastric poison and contact effect, strong permeability on the leaf surface of plants, has a certain systemic effect, and does not kill eggs.
Indanoxida: has gastric poison and contact effect, no systemic effect, no egg killing.
Fenazide: no osmotic effect and phloem systemic activity, mainly through gastric toxicity, but also has a certain degree of contact and strong eggicidal activity.
Lice mite urea: with gastric poison and contact effect, no systemic system, strong egg killing.
Methyl salt: mainly gastric poison, combined with contact effect, its insecticidal mechanism is to hinder the motor nerve of pests.
All five are mainly gastric poison and contact killing, and the addition of penetrant/expander (pesticide auxiliary) will greatly improve the killing effect.
Two. Insecticidal spectrum comparison
Insectitrile: has excellent control effect on drill borer, stinging and chewing pests and mites, especially against diamondback moth, beet moth, striated night moth, leaf curling borer, American spotted loon fly, pod borer, thrips, red spider spider and other effects;
Indanecarb: mainly used to control Lepidoptera pests such as beet moth, diamondback moth, cabbage moth, twill moth, cotton bollworm, tobacco green worm, leaf curly moth and so on.
Chlorfenazide: It is mainly unique to all lepidopteran pests, and has special effects on resistant pests such as bollworm, cabbage worm, diamondback moth, beet moth, etc.
Lice mite urea: mainly used to control leaf curly borer, diamondback moth, cabbage green worm, beet moth, striated night moth and white whitefly, thrips, rusty tick and other pests, especially in the control of rice longitudinal leaf borer.
Methyl salt: highly active against the larvae of lepidopteran insects and many other pests and mites, both gastric toxicity and contact effect. It has good control effect on lepidopteran armyworm, potato tuber moth, beet moth, apple stupid moth, peach small heartworm, rice dichemical borer, three chemical borer, cabbage green worm, European corn borer, melon leaf curl borer, melon silk borer, melon wild borer, and tobacco green worm. It is especially effective against Lepidoptera and Diptera.
Insecticidal broad spectrum: methyl salt> chlorfenitrile> lice mite urea> indenadecarba≥ carboxylahydrazide
Third, the speed of dead insects is compared
Chlorfenapyr: 1 hour after the application of pest activity weakens, spots appear, color changes, activity stops, coma, paralysis, eventually leads to death, 24 hours to reach the peak of dead insects.
Indanoxida: Insects stop feeding within 0-4 hours, are paralyzed, and the coordination ability of insects will decrease (which can cause larvae to fall from crops), and generally die within 1-3 days after the drug.
Chlorhydrazide: After the pest feeds, it can interfere with and destroy the original hormone balance in the insect's body, and lead to food refusal, generally 5 hours after feeding, the pest stops harming, 1-2 days of peeling reaction, 2-3 days lead to incomplete peeling, refusal to eat, whole body dehydration, and finally death, about 3 days to reach the peak of dead insects.
Lice mite urea: After the pest comes into contact with the agent and eats the leaf with the agent, the mouth is anesthetized within 2 hours, and the feeding is stopped, thereby stopping the damage to the crop, and the peak of dead insects is reached in 3-5 days.
Methyl salt: The pest is irreversibly paralyzed, stops eating, and dies after 2-4 days, and the rate of insecticide is slow.
Insecticidal rate: chlorfenapyr> indenidoxcarb> chlorfenhydrazide> lice mite urea > methyl salt
Four. Comparison of validity periods
Insectitrile: does not kill eggs, only has outstanding control effect on elderly insects, and the insect control time is about 7-10 days.
Indanoxida: does not kill eggs, kills lepidopteran pests of all sizes, and the control effect is about 12-15 days.
Chlorhydrazide: It has good egg-killing ability, and pests will form chemical sterilization after feeding, so the effective period is long, generally about 15-30 days.
Lice mite urea: has a strong egg-killing effect, and the insect control time is relatively long, up to 25 days.
Methyl salt: long shelf life, 10-15 days for pests and 15-25 days for pest mites.
Effective period: Methyl salt> lice mite urea≥ chlorhydrazide> indenidox > chlorfena
5. Comparison of leaf preservation rate
The ultimate purpose of pesticide is not to let pests harm crops, as for the speed or slowness of pest death or more or less, it is only a matter of people's perception, and the level of leaf preservation is the final indicator to measure the value of the product.
According to the comparison of the control effect of rice leaf borer, the leaf preservation rate of lice mite urea can reach more than 90%, the methyl salt reaches 80.7%, the indanoxil reaches 80%, the fenazide reaches about 65%, and the chlorfenazide reaches about 65%.
Leaf preservation rate: lice miteurea> methyl salt> indenidoxcarb> chlorhydrazide ≥ chlorfenamine
6. Security comparison
Lice mite urea: so far there is no drug damage, and the agent will not cause stinging pests to run rampant again, and has a mild effect on adult beneficial insects and feeding spiders.
Chlorfenitrile: sensitive to cruciferous vegetables and melon crops, easy to produce drug damage when used at high temperatures or high doses;
Indanoxurandol: Highly safe, no drug reaction, vegetables or fruits can be picked and eaten the next day of application.
Pyrhydrazide: It is also highly safe, no drug reaction, and can cause chemical sterilization of some lepidopteran pests after use, and there will be a second dead insect stage after 10 days, and there are no toxic side effects on bees, predatory mites, etc., so it is highly safe.
Methyl salt: Highly safe for all crops in protected areas or 10 times the recommended dosage, an environmentally friendly, low-toxicity pesticide.
Safety: Methyl salt≥ chlorhydrazide≥ indenofuran> lice mite, urea, > chlorfenitrile
Seven. Cost comparison of medications
Calculated according to the quotation of each manufacturer and the dosage used in recent years.
The comparison of drug costs is: indenoxcarb> chlorfenapyr> chlorhydrazide> lice mite urea > methovitan salt
The general feeling of the five agents in practical use:
The effect of lice mite urea felt very average when used for the first time, and the effect felt very unusual when used twice in a row.
Inpronil, on the contrary, feels very good when used for the first time, and feels very ordinary after two consecutive uses.
The effects of methyl salt, indanoxuran and fenachydrazide are roughly somewhere in between.
For the current situation of pest resistance, it is recommended to adopt the method of "prevention first, comprehensive prevention and control", and take measures (physical, chemical, biological and other measures) to effectively control and control at the early stage of occurrence, so as to reduce the frequency and amount of medication used in the later stage and delay drug resistance.
When taking pharmaceutical control agents, it is recommended to combine with plant-derived or bio-derived insecticides such as pyrethroids, matrin, matrine, etc., and mix and rotate them with chemical agents to achieve the purpose of alleviating drug resistance; When chemical agents are used, it is recommended to use compound preparations and use them alternately to achieve good prevention and control effects.
Precautions for chlorfenapyr
Insecticide chlorfenitrile is sensitive to crops such as watermelon, zucchini, bitter melon, melon, melon, winter melon, pumpkin, hanging melon, loofah and so on.
Avoid using the drug at high temperature time, flowering stage, and seedling stage.
Insecticide chlorfennitrile is prone to drug damage, so on the one hand, sufficient field tests must be done before product promotion, experimental data must be accumulated, and the content and dilution factor that are relatively safe for crops must be screened. On the other hand, the original drug supplier tries not to change easily, and the supply of co-solvent should also be relatively stable.
The pesticide chlorfenitrile is mainly caused by: the impurities in the original drug of chlorfennitrile are more sensitive to some crops, and if the original drug content is low or the content of the preparation is high, it is easy to produce drug harm, so the original drug with high original drug content is selected as much as possible in the selection, so as to try to avoid its high impurity content and cause drug harm. It is understood that some foreign companies have requirements for their impurity content when purchasing original drugs, of course, this will also increase the cost of original drug procurement.
Cruciferous crops (cabbage, radish, rape and other crops) are used before 10 leaves, which are prone to drug damage, do not use.
Only 2 times are allowed to be used per vegetable to avoid drug resistance; The safe interval on cruciferous vegetables is tentatively set at 14 days, and caution should be used on cucumbers, lettuce, tobacco, melon vegetables.
Insecticide chlorfenapyr is toxic to fish and cannot be spread directly to water and water sources.
