Abamectin is a kind of antibiotic insecticide, acaricide and nematicide developed in cooperation with Merck (now Syngenta) of the United States, which was isolated from the soil of the local Streptomyces Avermann by the University of Kitori in Japan in 1979. It can be used to control pests such as mites, lepidoptera, homoptera, coleoptera, root-knot nematodes on most crops, fruit trees, flowers and trees, such as diamondback moth, fruit tree leafminer, beetles, forest pine caterpillars, red spiders, thrips, planthoppers, leaf miner, aphids, etc.
1 Abamectin · Fluazinam
Fluazinam is a new pyrimidine bactericidal and acaricidal agent. It was reported that it has bactericidal effect in 1982. In 1988, it was a compound developed and launched by Syngenta by Ishihara Corporation of Japan. In 1990, Fluazinam, a 50% wettable powder, was first listed in Japan. Its mechanism of action is mitochondrial oxidative phosphorylation coupling agent, which can inhibit the whole process of the development of infected bacteria. It can not only effectively inhibit the release and germination of the pathogen’s zoospores, but also inhibit the growth of the pathogen’s mycelium and the formation of invasive organs. It has strong protection, but no inhibitive and therapeutic properties, but has good persistence and resistance to rain erosion.
The compound formulation of Abamectin and haloperidine is generally used to control plant pest mites, which can not only effectively control phytophagous mites such as spider, but also prevent the occurrence of various diseases.
2 Abamectin · pyridaben
Pyridaben, a thiazidone insecticide and acaricide, was developed by Nissan Chemical Co., Ltd. in 1985. It is active against the eggs, nymphs and adult mites of most harmful mites, such as panonychus mites, gall mites, leaf mites and small claw mites, and also has certain control effects against aphids, yellow striped fleas, leaf hoppers and other pests. Its action mechanism is a non-systematic insecticide and acaricide, that is, it mainly inhibits the synthesis of certain mold in the muscle tissue, nerve tissue and electron transmission system of pests. It has strong contact killing property, but has no internal absorption and fumigation effect.
Avi · pyridaben is mainly used to control harmful mites such as red spider, but because pyridaben has been used on various crops for a long time and many times, its resistance is also large, so this kind of pesticide is recommended to be used to prevent and control harmful mites when they do not occur or in the early stage of occurrence. There are mainly emulsion, microemulsion, wettable powder, water emulsion and suspension agent.
3 Abamectin · Etoxazole
Etimazole is an oxazoline acaricide, a diphenyl oxazoline derivative acaricide discovered and developed by Sumitomo Corporation of Japan in 1994. It can be used for most harmful mites such as Tetranychus urticae, Tetranychus holoclavatus, Tetranychus originalis and Tetranychus cinnabarinus on fruit trees, melons and vegetables, flowers and other crops. Its mechanism of action is chitin inhibitor, that is, inhibiting the embryo formation of mite eggs and the peeling of young mites to adult mites. It has the effects of contact killing and stomach toxicity, and has no internal absorption. It has high activity against mites eggs, young mites and nymphs, and has poor effect on adult mites, but it can inhibit the spawning or hatching of female adult mites, and is resistant to rain erosion.
Avenidazole is suitable for use at the early stage of the outbreak of harmful mites or when it is just discovered.
4 Abamectin · Bifenazat
Bifenazat is a kind of Bifenazat acaricide, which was discovered by the original Uniroy Company (now Koju Company) in 1996, and then developed jointly with Nissan Chemical in Japan. It was listed in 2000 as a hydrazine formate (or diphenylhydrazine) acaricide. This drug is not only more effective than ethyndrite, but also safer for plants. It is used for many kinds of harmful mites such as Tetranychus urticae, Tetranychus flavus, Tetranychus totalis, etc. on fruit trees, vegetables, ornamental plants and melons. It has contact killing effect, no internal absorption, and does not affect the use effect at low temperature. It is effective for all life stages of mites (eggs, nymphs and adult mites) and has egg killing activity and knockdown activity against adult mites. Its mechanism of action is the inhibition of nerve cells, that is, to the central nervous conduction system of mites γ— The unique function of aminobutyric acid (GABA) receptor can inhibit the central nerve conduction system of mites to achieve the effect of killing.
Avil · Bifenazat ester is not only highly effective in killing, but also not easy to produce drug resistance. It can be used on most crops.
6 Abamectin · Hexythiazox
Thiazolidinone is a kind of acaricide produced by Caoda Company of Japan. It is mainly targeted at spider mites, and has low activity against rust mites and gall mites. Its mechanism of action is non-system acaricide, which has the effects of touch killing and stomach toxicity, and has no internal absorption conductivity, but has a good penetration effect on the plant epidermis. It has excellent activity against mites eggs and young mites. Although it has weak toxicity to adult mites, it can inhibit the hatching of female adult mites eggs. Non-thermal acaricide, that is, it does not affect the acaricidal effect at high or low temperature.
Ave · Hexythiazox can be used to control crop spider mites or spider mites in many periods, but its effect on adult mites is not good. It is recommended to control them in the early stage of occurrence, and there is no difference in the effect when the environmental temperature changes greatly.
7 Abamectin · Diafenthiuron
Diafenthiuron is a new thiourea pesticide developed by Ciba-Kaji (now Syngenta) in the 1980s. It is used to control Lepidoptera pests such as diamondback moth, cabbage worm, bean armyworm on various crops and ornamental plants, as well as pteroptera pests such as leafhopper, whitefly and aphid, as well as phytophagous mites such as spider spider (spider mite) and tarsal mite. It has the effects of touch killing, stomach poisoning, fumigation and internal absorption. Diafenthiuron has a slow effect on eggs, larvae, nymphs and adults, but its effect on eggs is not good. Its mechanism of action is that it has biological activity only after it is decomposed into carbodiimide derivatives under sunlight (ultraviolet) or under the action of multifunctional oxidase in the insect body, and carbodiimide can selectively covalently combine the Fo-ATPase and outer membrane pore protein in the inner membrane of mitochondria to inhibit the mitochondrial respiration, hinder the function of nerve cell mitochondria in the insect body, affect its respiration and energy conversion, and make the insect dead.
Avidin can not only control harmful mites such as spider mites and tarsal mites in crops, but also have good control effect on lepidoptera and homoptera pests, but has poor effect on mites or insect eggs. It can be used in combination with other types of pesticides with strong quick effect or long duration, and can be used in combination with other egg killers, such as tetrapyrazine. It is also sensitive to some vegetables, such as cauliflower and broccoli, and it is not recommended to use it during flowering.
8 Abamectin · Propargite
Propargite is a kind of organic sulfur acaricide, developed by the former Uniroy Company of the United States (now Copua Company of the United States) in 1969. Its mechanism of action is mitochondrial inhibitor, that is, by inhibiting the synthesis of mitochondrial energy (ATP) of mites, thus affecting the normal metabolism and repair of mites and killing mites. It has the effects of gastric toxicity, contact killing and fumigation, has no internal absorption and permeability, and has significant activity at higher temperatures. It has good effects on young mites, nymphs and adult mites, but low activity on mites eggs. ① Increasing the concentration under high temperature will cause recoverable damage to the tender parts of crops. ② It has the characteristics of quick effect, long duration of effect, and low residue (because of its non-permeability, most of the liquid medicine will only remain on the surface of plants). It can be used for the control of most harmful mites such as leaf mites, tea yellow mites, leaf mites, gall mites, etc. on various plants such as melons, cruciferous vegetables, fruit trees, cotton, beans, tea trees and ornamental plants.
Avi – acetyl mites can control many kinds of harmful mites on crops. At a certain temperature, the higher the temperature is, the more significant the control effect is, but the effect on mites eggs is weak, and the excessive dose will produce certain recoverable symptoms on the tender parts of crops.
9 Abamectin · fenpropathrin
Fenpropathrin is a pyrethroid insecticide and acaricide developed by Sumitomo in 1973. It can be used for aphids, cotton bollworm, cabbage worm, diamondback moth, leafminer, tea leafhopper, inchworm, heartworm, flower shell worm, poisonous moth and other pests of Lepidoptera, Homoptera, Hemiptera, Diptera, Coleoptera and other pests on cotton, fruit trees, vegetables and other crops, as well as for preventing red spider and other harmful mites. It has the effects of contact killing, stomach toxicity and repellency, and has no inhaling and fumigating effects. It is active to the eggs, young mites, nymphs, young mites and adult mites of harmful mites. Its action mechanism is nerve poison, that is, it acts on the nervous system of pests, destroys the nerve conduction process of pests, and makes them overexcited, paralyzed and dead. The effect is remarkable at low temperature, but it cannot be used at high temperature, which is easy to cause drug damage.
Avermethrin can be used to control crops with more spider mites or red spiders, but the control effect depends on the situation. Because fenpropathrin is a pyrethroid, it generally has no mutual resistance with other kinds of acaricides, but it can control a variety of harmful mites, and it is easy to produce drug resistance, and it can also control a variety of lepidoptera, stinging mouthpiece and other pests, but the reason for the excessive variety of pyrethroids and the use of many years, The prevention and control effect may not be ideal, so it is recommended to use prevention first. The dosage forms include emulsifiable oil, microemulsion and wettable powder.
10 Abamectin · Profenofos
Profenofos is a thiophosphate organophosphate insecticide and acaricide developed by Ciba-Kaji (now Syngenta) in 1975. It can prevent and control the stinging mouthpiece, chewing mouthpiece or lepidoptera pests and mites on rice, cotton, fruit trees, cruciferous vegetables, ornamental plants, areca, coconut and other plants, such as cotton bollworm, rice leaf roller, diamondback moth, nocturnal moth, aphid, thrips, red spider, rice planthopper, leaf miner and other pests. Its action mechanism is acetylcholinesterase inhibitor, which has contact and stomach toxicity, strong permeability to crops, good quick effect to pests, and egg killing effect to pests and mites. But there is no internal absorption. It can be quickly absorbed by the plant surface, and has certain transfer ability in the plant body. It can be transmitted to the edge of the leaves to kill its pests, and Profenofos has a strong inhibitory effect on the activity of insect acetylcholinesterase, which weakens the drug resistance of pests. Because most of the organic phosphorus has certain activity against harmful mites, the same kind of agents, avirin and Profenofos, can be used to prevent harmful mites.
11 Abamectin · chlorpyrifos
Chlorpyrifos is an organophosphorus pesticide developed and produced by Taoshi Yinong in 1965. It was forbidden to use on melons and vegetables in China on December 31, 2014, and completely banned in some areas (such as Hainan, etc.) from 2020. It has the effects of touch killing, stomach poisoning, and fumigation, but has no inhalability. After use, it will inhibit the activity of acetylcholinesterase in the body of pests, causing them to move out of balance, overexcitation, and spasm to death. It can be used for the control of borers, noctuids and other lepidoptera and coleoptera on rice, corn, soybeans, fruit trees and other crops, as well as underground pests such as stem borers and ground tigers, and various pests such as leafminer.
Abamectin and chlorpyrifos have registered more than 60 kinds in China, and are mainly used to control lepidoptera pests of fruit trees, ground tigers, grubs, root-knot nematodes and other underground pests. Like most organic phosphorus such as Profenofos, they have certain activity against most harmful mites, and can also play a role in preventing harmful mites.
