BTS 27271 - Uses and synthesis methods
broad-spectrum acaricide
Monoformamidine, also known as mite killing amidine, mite lice, monoformamidine hydrochloride, egg mite double net, caterpillar mite clear, mite net, is a kind of organic nitrogen broad-spectrum formamidine Acaricides are homologs of amitraz. Chemical name: N-(2,4-xylene)-N & prime;-methyl formamidine. The products sold on the market are mostly monoformamidine hydrochloride, with a light yellow or brown liquid appearance, a density of 1.090~1.105, a pH value of less than 1, no combustion, and corrosive to metals. Pure product is white needle-like crystal with melting point of 163~165 ℃, soluble in water, acidic aqueous solution, slightly soluble in low molecular weight alcohol, insoluble in organic solvents such as benzene and petroleum ether. Stable to light and heat. It has contact killing and fumigation effects on harmful mites, and is effective on the insect state of each stage of the spider mite family. The efficacy is better at high temperature (above 22 ℃). The effect on overwintering eggs is poor. It mainly inhibits the activity of monoamine oxidase and induces excitation on non-cholinergic synapses of the central nervous system. Mites that are resistant to other acaricides are also effective. Monoformamidine can be mixed with organophosphorus and pyrethroid pesticides, which has a synergistic effect and can expand the insecticidal spectrum. It is mainly used to control plant-eating leaf mites and cotton aphids on various crops such as fruit trees, tea, cotton, vegetables, etc.; it can also be used to control livestock lice and bee mites. Poisoning to humans and animals, poisonous to fish.
Toxicity
The original drug is poisoning, and it is a low-toxic pesticide according to my country's pesticide toxicity classification standard.
safe interval: stop using fruit 20 days before harvest. The original drug oral acute LD50 male rats was 215mg/kg, female was 245mg/kg, male was 265mg/kg, female was 250mg/kg. Percutaneous acute LD50>2g/kg. No teratogenic and mutagenic effects. Accumulated toxicity is very small. It has certain influence on micronucleus of mouse bone marrow cells. It has no irritating effect on rabbit skin and slight irritating effect on rabbit eyes. 25% The oral acute LD50 of monomethidine aqua is 950 mg/kg for male rats and 780 mg/kg for female rats. It has a slight irritation effect on the face and eyes when the temperature is high.
amitraz
amitraz is also called mite, diworm amidine, and fruit mite killing. It is a broad-spectrum formamidine acaricide, which is a moderately toxic acaricide. In 1971, Palmer (B.H.Palmer) and others reported its acaricide activity. In 1973, Boots Co.Ltd. recommended it as an acaricide. Chemical name: 1, 5-bis-(2, 4-dimethylphenyl)-3-methyl -1,3, 5-triazopentadiene -1,4, the original drug is white or yellow needle-like crystal, with the taste of some carbon amine, the density is 0.3, the melting point is 86~87 ℃, the vapor pressure is 506.6 × 10-7Pa at 20 ℃, and it is slightly soluble in water, soluble in various organic solvents such as xylene, acetone and methanol. It is stable to temperature and light under anhydrous conditions. Unstable under acidity. Non-flammable, non-explosive, long-term storage in humid places easy to decompose and deteriorate. It has the effects of contact killing, food rejection and repellent, as well as certain stomach poison, fumigation and internal absorption. It is effective for various insect states of Tetranychidae, but it is less effective for overwintering eggs. It has a variety of toxic mechanisms, mainly inhibiting the activity of monoamine oxidase, and inducing excitatory effects on non-cholinergic synapses in the central nervous system of the mites. Harmful mites that are resistant to other acaricides also have higher activity. The efficacy period can reach 40~50 days. It is mainly used for fruit trees, vegetables, tea, cotton, soybeans, sugar beets and other crops to control various harmful mites. It also has a good control effect on psyllids, and is effective on some lepidopteran pest eggs. It also has a certain treatment effect on scales, aphids, cotton bollworms, red bollworms, etc., and can also prevent cattle, goats and bee mites. Amitraz can be mixed with organophosphorus, pyrethroids, abamectin and other pesticides, which has a synergistic effect and can expand the insecticidal spectrum. The mixed preparation includes 10.8% Avi Shuangjia EC.
control object
citrus red spider, citrus rust tick, four-spotted yellow spider, apple red spider, cotton red spider, eggplant and beans on the red spider, tea orange gall mite, arrow light scale, red wax scale and blowing scale 1~2 years old nymphs, aphids and wood lice, etc. It is safer for ladybugs, lacewings, parasitic wasps and bees. It can also be used to control ticks, scabies and bee mites in vitro.
how to use
(1) citrus red spider. When the temperature before and after flowering is above 20 ℃ or in autumn and there are 3~5 mites per leaf, spray with 1000~2000 times of 25% monoformamidine aqua, the control effect is better, and the effective period is about 20 days.
(2) Citrus rust ticks. From June to September, when there are 2~3 mites in each field of vision or individual damaged fruits appear in the fruit orchard, spray 1500~2500 times of 25% monoformamidine aqua has a good control effect, and the effective period can reach about 3 weeks.
(3) Four-spotted yellow spider. When the temperature is above 20 ℃ and there are 2~4 mites per leaf, spray with 25% monoformamidine aqua 1000 times liquid, which has a good control effect. The duration is about 14 days.
(4) apple red spider. When the temperature above 20 ℃ before and after apple flowering reaches the control index, spray with 1000~1500 times of 25% monoformamidine aqua has a good effect on mites and eggs. And can also treat aphids.
(5) control of hawthorn spider mites and apple claw mites. After apple flowers fall, when the density of spider mites is not large, spray the crown evenly with 1000 times of 25% monomethamidine aqua, and the effective control period is about 30 days. If the mite mouth density is large in summer, the use concentration needs to be increased to 500 times the liquid effect is good.
(6) cotton red spider. In the egg hatching, if the mites are in full bloom with 25% monoformamidine aqua 1000~1500 times liquid spray, the control effect is better.
(7) control cotton aphid and cotton spider mites. For the control of cotton aphids, use 25% monoformamidine aqua 800~1500 times liquid; for the control of aphids and cotton spider mites, use 500~1000 times liquid.
(8) mealybug, red wax mealybug and blown mealybug. When 1~2 instar nymphs are in full bloom, the control effect can reach about 90% by spraying 500~1500 times of 25% monoformamidine aqua. (9) Prevention and control of tea orange gall mites. Spray with 1500 times of 25% monoformamidine aqua.
precautions
(1) Toxic to humans and animals, avoid eating by mistake. Attention should be paid to protection when spraying. If the skin touches the liquid medicine, it is easy to cause itching and erythema. In the high temperature season in summer, protection should be strengthened. Wash hands and face with soap and water after application.
(2) it should be stored in a cool, dry and ventilated place, and should not be mixed with food.
(3) The application effect is poor below 20°C. Sometimes when the temperature is high, the medicine has a stimulating effect on the face and eyes, and should be avoided under high temperature and strong light.
(4) poisonous to fish, do not let chemicals pollute rivers and ponds, etc.
(5) The agent has strong permeability and rains 2 hours after spraying, which does not affect the efficacy. The control effect is closely related to the temperature, and the control effect is good when the temperature is above 20 ℃. Monoformamidine agents mixed with organophosphorus and pyrethroid pesticides have a synergistic effect and can expand the insecticidal spectrum. But it cannot be mixed with alkaline pesticides, otherwise it will reduce the efficacy. When dispensing, hard alkaline well water should not be used, otherwise the efficacy will decrease.
(6) if you swallow this product, you should immediately reach your hand into your throat to induce vomiting and send it to the hospital for treatment. the poisoned person is recommended to be treated according to amidine compound poisoning. Safety should be stopped 20 days before harvesting.
Preparation method
In the xylene solution of 2, 4-diphenylamine and N-methylformamide, drip phosphorus oxychloride under stirring, after dropping, raise the temperature to 70 ℃, continue to stir and react for 3 hours, and obtain monoformamidine after cooling, washing with water, neutralization, etc. 25% aqua is monoformamidine hydrochloride.
