Brief analysis A powerful insecticide and acaricide etoxazole
What is etoxazole (153233-91-1)?
The pesticide etoxazole is a new type of special acaricide in the oxazole family. Etoxazole is a chitin synthesis inhibitor, Cas 153233-91-1. Etoxazole kills harmful mites by inhibiting the embryogenesis of mite eggs and the molting process from young mites to adult mites. It has contact and stomach poisoning effects. It has no internal absorption, but has strong penetration ability and is resistant to rainwater erosion. Etoxazole is extremely lethal to mite eggs and young nymphs. It does not kill adult mites, but it can significantly inhibit the hatching rate of eggs laid by female adult mites, and can prevent and control harmful mites that have developed resistance to existing acaricides.
The insecticide etoxazole is a non-systemic acaricide with contact killing and stomach poisoning effects and strong penetrating effect. It is effective in controlling mites such as spider mites and Panonychus mites on citrus, cotton, fruit trees, flowers and other crops.

The miticidal mechanism of etoxazole (153233-91-1)
The insecticide etoxazole is a diphenyloxazoline derivative. Its mode of action mainly inhibits the synthesis of chitin, hinders the embryogenesis of mite eggs and the molting process from young mites to adult mites, so it can effectively prevent and control the entire juvenile stage of mites (eggs, young mites and nymphs). Effective on eggs and young mites, but ineffective on adult mites.
The mechanism of action of etoxazole (153233-91-1)
The insecticide etoxazole is a benzoylphenylurea insect growth regulator, which mainly inhibits the formation of insect cuticles. The mechanism of action of etoxazole is similar to this. Etoxazole achieves the purpose of killing mites by inhibiting the formation of N-acetylglucosamine (chitin precursor) in the mature epidermis of insects. It has the characteristics of high selectivity, high efficiency, low toxicity and long duration. Many acaricides mainly achieve acaricidal purposes by poisoning nerves and inhibiting respiration, such as thiazolones and permethrin. However, etoxazole has a unique mechanism of action and has no cross-resistance with the above-mentioned insecticides.
Characteristics of etoxazole (153233-91-1)
The insecticide etoxazole inhibits the embryogenesis of mite eggs and the molting process from young mites to adult mites. It is effective on eggs and young mites, but is ineffective on adult mites, but it has a good sterile effect on female adult mites.

The difference between etoxazole (153233-91-1) and spirodiclofen
Both etoxazole and spirodiclofen are acaricides with relatively long durations. They are effective against eggs and young nymphal mites, but are ineffective against adult mites. Their duration of effect can reach more than 30 days, but spirodiclofen can be used year-round. In some areas, spider mites are somewhat resistant. Etoxazole is a long-lasting acaricide that has emerged in the past two years. Etoxazole has a stable control effect under low temperature conditions. These two acaricides are compounded with abamectin or auxiliaries. All have a certain synergistic effect, and the effect is better when used in the early stages of mite infestation. Now this year, some cotton farmers use etoxazole or spirodiclofen once in May-June, and the mite infestation is at a low level throughout the year.
Precautions for etoxazole (153233-91-1)
The insecticide etoxazole has a slow miticidal effect and is suitable for spraying in the early stages of mite occurrence, especially during the egg hatching period. When the number of harmful mites is large, it can be mixed with avermectin, pyridazolin and triazoltin that kill adult mites.
Do not mix it with Bordeaux mixture. Orchards that have used etoxazole must wait at least two weeks before using Bordeaux mixture. Once Bordeaux mixture has been used, etoxazole should be avoided. Otherwise, phytotoxicity such as burning leaves and fruits may occur. Some fruit tree varieties have adverse reactions to this agent, so test it first before using it on a large area.
How do pesticide companies lay out etoxazole (153233-91-1)
First, pay attention to the trend of compounding. The currently registered compounding objects of etoxazole are mainly abamectin, pyridaben, bifenazate, spirotetramat, spirodiclofen, triazoltin, etc. Among them, diphenylhydrazine and abamectin have higher market appeal, and they can complement each other's advantages and achieve the effect of 1+1>2. To further expand the etoxazole market, more excellent compounding solutions need to be developed.
Second, use the advantages of etoxazole to kill mites and expand its application to more crops. Etoxazole is a contact-killing and selective acaricide that is non-temperature-sensitive and has a unique structure. It is safe, efficient, and long-lasting. It can effectively prevent and control harmful mites that are resistant to existing acaricides, and has good Excellent resistance to rain erosion. If there is no heavy rain 2 hours after application, no need to re-spray. Currently it is mainly used for citrus, cotton, apple and other crops. Future research and development will also focus on more cash crops.
Third, the technique of using etoxazole needs to be paid attention to. This agent has a slow miticidal effect and is suitable for spraying in the early stages of mite occurrence, especially during the egg hatching period. When the number of harmful mites is large, it can be mixed with avermectin, pyridazolin and triazoltin that kill adult mites. It should be noted that etoxazole cannot be mixed with Bordeaux mixture. Orchards that have used etoxazole must wait at least two weeks before using Bordeaux mixture. Once Bordeaux mixture has been used, avoid using etoxazole again, otherwise phytotoxicity problems such as leaf burning and fruit burning may occur. Therefore, in terms of application promotion, the use of technology should be focused on promoting and publicizing it at the grassroots level.
Fourth, pay attention to using it in conjunction with functional additives. Take the two-spotted spider mite as an example. Its back is curved, has micro-nano structure and roughness, and is highly hydrophobic. General pesticides need to be diluted hundreds to several dry times. The surface tension is high and cannot wet the spider mite body well. surface. In this case, the scientific and rational use of functional additives has become an effective means to increase the efficiency of acaricides.
Fifth, improve the processing level of preparations, such as nanopesticides. Nanopesticide is a pesticide preparation product created by using nanomaterials and preparation technology to efficiently combine the original drug, carrier and adjuvant. This type of product can well solve the problems of traditional pesticides such as environmental pollution, bioaccumulation, and a substantial increase in pest resistance, and will become a powerful tool for farmers in plant protection operations. This technology has good application prospects. If it is applied to etoxazole, it has great potential to be tapped.
Etoxazole (153233-91-1) market analysis
In the acaricide market, etoxazole and its compound products still occupy a dominant position, mainly single doses and compounded with abamectin, bifenazate, spirodiclofen, spirotetramat, etc. The highest proportion of etoxazole is used in combination with bifenexate and abamectin.
Because of its good temperature sensitivity and high miscibility, ethofenazole is a mainstream acaricide besides ethofenazole. However, under the current market conditions, the acaricide market is relatively sluggish, and the dosage and frequency of medication are reduced. Acaricides with relatively low prices and higher cost performance on the market will replace part of the etoxazole market.
In terms of terminal applications, it is recommended to apply pesticides scientifically to reduce the occurrence of drug resistance; develop more combination solutions to extend the use cycle of pesticides; improve drug efficacy and reduce harm to the environment through research and development of plant protection application technology and preparation processing will also be future developments inevitable trend.
