A brief analysis of the pesticide insecticide omethate
What is omethate (1113-02-6)?The pesticide omethate is an organic compound with the chemical formula C5H12NO4PS. Cas 1113-02-6 is a systemic organophosphorus insecticide and acaricide. It is mainly used to control pests in cotton, wheat, sorghum and other crops.
The insecticide Omethoate is a colorless and transparent oily liquid. The industrial product is a light yellow oily liquid. It is easy to decompose when exposed to alkali and is relatively stable in neutral and acidic solutions. It is a highly toxic, broad-spectrum organophosphorus insecticide and acaricide. It has fast knockdown effect on pests, strong systemic and contact killing effects and certain gastric poisoning effects. The dosage form is 40% emulsifiable concentrate. Omethoate is highly toxic to humans and animals and is a highly toxic pesticide. Therefore, special attention should be paid when using it. Omethoate is easily hydrolyzed, and the aqueous solution cannot be stored for a long time. The medicinal solution must be prepared as needed, otherwise the efficacy will be reduced. It is prohibited to use omethoate on cabbage.
omethate (1113-02-6) function
The insecticide Omethoate also has a strong systemic insecticidal effect. It can be sucked into the human body by the stems and leaves of the plant, and can be transferred to the parts where the pesticide is not sprayed, poisoning and killing the pests that harm it. Therefore, when using omethoate, the method of spraying the stems can be used. In general, the temperature has little effect on the efficacy of omethoate. Omethoate is a highly toxic pesticide, but it does not easily penetrate into the human body from the skin, and its contact toxicity is not much different from that of dimethoate.
The insecticide Omethoate is based on the principle that dimethoate is oxidized and metabolized in the body to form a compound with greater toxicity and toxicity than dimethoate. The original drug of organophosphorus pesticides synthesized in factories is an orange oily liquid with a strong onion and garlic smell. It is soluble in water, but the stability of the aqueous solution is worse than that of dimethoate, and it is easier to decompose and fail. Omethoate is relatively stable in neutral and acidic solutions, but will quickly decompose under alkaline conditions.
The insecticide Omethoate has a strong contact killing effect on pests and mites, especially some aphids that have become resistant to dimethoate. It is highly toxic and can still maintain strong toxicity during low temperature periods. It is mainly used as a good pesticide to control various aphids, leaf rollers, Spodoptera litura, flower thrips and stink bugs on bananas. The insecticidal effect of omethoate during low temperature period is faster than that of dimethoate. Omethoate also has a strong systemic insecticidal effect. It can be sucked into the plant by the stems and leaves of the plant, and can be transferred to the part where the pesticide solution is not sprayed, poisoning and killing the pests harming it.

Omethoate is a highly toxic pesticide, but it does not easily penetrate into the human body from the skin, and its contact toxicity is not much different from that of dimethoate.
In addition to being a systemic agent, it also has a strong contact killing effect. It has a wide insecticidal spectrum and can be used to control a variety of pests with sucking and chewing mouthparts and spider mites in vegetables, fruit trees, tea, mulberry, cotton, oil crops, and grain crops. Generally, 30 to 40 grams of active ingredients are used per mu. It is more effective against aphids, and only 15 to 20 grams of active ingredients per mu can be used. It has special effects on leafminers on vegetables, beans, etc., with a special effect period of about 10 days. The main dosage form is 40% emulsifiable concentrate, and there are also ultra-low-volume oil formulations and soluble powders. It has low toxicity and is quickly degraded into non-toxic demethylmethoate and dimethoate by glutathione transferase and carboxamidase in cattle, so it can be used to prevent and control parasites inside and outside livestock.
Dimethoate can be rapidly oxidized into omethoate both inside and outside plants and in insects, thereby increasing its toxic effects. The omethoate produced in the factory is called omethoate (40% EC), and its prevention and control targets and application scope are the same as those of dimethoate. However, due to its high toxic effect, it is also more effective when the temperature is lower, and the dosage can be about 1/3 less than dimethoate. Cotton aphids that are resistant to dimethoate can still be effectively controlled with dimethoate, especially in early spring when controlling overwintering cotton aphids on peppers, pomegranates and hibiscus.
omethate (1113-02-6) uses
The insecticide omethate is mainly used to control piercing- and sucking-mouthed pests, and is also effective against chewing-mouthed pests.

Is omethate (1113-02-6) effective in killing spider mites?
The insecticide omethate can kill spider mites, but it is not particularly effective.
Spider mites belong to the family Tetranychidae and are a common plant pest. The leaves of the affected plants show grayish-yellow spots or patches, and the leaves become withered and yellow, or even fall off.
Spider spiders have a strong reproductive capacity. Under high temperature and drought conditions, they reproduce rapidly and cause serious harm. When spider mites are found on plants, they should be sprayed as soon as possible for control. Commonly used agents include dicofol, dicofol emulsifiable concentrate, dicofol wettable powder, and dicofol emulsifiable concentrate, etc., which can achieve ideal control effects. When spraying, move the potted flowers outdoors and prepare the pesticide according to the instructions. Spray the pesticide evenly, paying special attention to the undersides of the leaves as well.
The pesticide omethate is highly toxic to humans and animals and is a highly toxic pesticide. Therefore, special attention should be paid when using it.
