| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| organotin acaricide | bentabutine organotin acaricide. In 1974, it was developed and put into production by Shell InternationalChemical Co. Ltd. It mainly plays a role in contact killing, and has strong lethality to juvenile mites and mites, but has little lethality to mite eggs. Harmful mites that are resistant to organophosphorus and organochlorine pesticides do not produce cross-drug resistance to them. It is a temperature-sensitive acaricide. The efficacy increases when the temperature is above 22 ℃, the activity decreases when the temperature is below 22 ℃, and the efficacy is poor when the temperature is below 15 ℃. It is not suitable for use in winter. After application, the pharmacodynamic effect is slow, and the activity begins to increase after 3 days, reaching the peak in 14 days, and the residual effect period is longer, reaching 2~5 months. It is highly toxic to aquatic organisms such as fish, low toxicity to birds and bees, and safer to predators such as mites, carnivorous ladybugs, and lacewings. It can be used for fruit trees, tea trees, flowers and other crops to control citrus red spiders, citrus rust mites, apple spider mites, tea orange gall mites, tea short beard mites, chrysanthemum spider mites, rose spider mites, etc. |
| toxicity | benzobutyltin is a low toxic acaricide. The acute oral LD50 of the original drug to rats is 2631mg/kg, mice 1450mg/kg, dogs> 1500mg/kg; Acute percutaneous LD50 in rabbits> 2000mg/kg, rats> 1000mg/kg; Acute inhalation of LC50 in rats was 1.83mg/L. It has a stimulating effect on the skin, eyes, and respiratory system. Rats were fed at a 2-year dose of 100mg/kg. Animal tests showed no cumulative toxicity and carcinogenic, teratogenic and mutagenic effects. It has high toxicity to fish, low toxicity to birds and low toxicity to bees. Rainbow trout LC50 is 0.27mg/L(48h), quail LD50 is 5065 mg/kg feed, and bee oral LD50 is 100 μg/animal. |
| use | organo-tin acaricide. It has good control effect on plant spider mites, gall mites, and rust mites, and has good activity on juvenile mites and adult mites. It is mainly contact killing, with long residual effect, no systemic effect, and poor effect on eggs. It has no interaction with organophosphorus-resistant mites and is safe for crops and natural enemies. When used at high temperatures, the efficacy is good. It is used to control spider mites in citrus, apple, pear, grape, tea tree, beans, eggplant, melon, tomato and other vegetables, and can also be used to control ornamental plant feeding mites. For example, to prevent and control citrus red spiders, spray 2000~2500 times with 50% wettable powder, and spray 2000 times with rust mites. Tetranychus and rust mites can be treated concurrently when they are complicated. 50% wettable powder for hawthorn and apple spider is sprayed with 1000~1500 times liquid, spider mites of eggplant, beans and other vegetables are sprayed with 1500~2500 times liquid, tea tree mites and orange gall mites are sprayed with 1000~1500 times liquid. bentabutine can effectively and continuously control herbivorous mites, and is suitable for apples, citrus, pears, grapes, hawthorn, tea trees, cotton, vegetables, flowers and other crops. used for citrus, grapes and other fruit trees and ornamental plants, to control a variety of active plant mites. The oral LD50 of rats is 2630mg/kg. It is relatively non-toxic to bees and toxic to fish. |
| Production method | The Grignard reagent prepared by the reaction of 2-chloromethyl-2-phenylpropane and magnesium reacts with tin tetrachloride to generate tris (2-Methyl-2-phenylpropyl) tin chloride, which is then desolated and condensed under the action of NaOH to form phenylbutyltin. First, 1-chloro-2-methyl-2-phenylpropane reacts with magnesium to prepare Grignard reagent, and then reacts with tin tetroxide to generate tris (2-methyl-2-phenylpropyl) tin chloride, and then under the action of sodium hydroxide to produce acaricidal tin. Raw material consumption quota: methallyl chloride 1700kg/t, benzene 1800kg/t, magnesium 300kg/t, tin 300kg/t, tetrahydrofuran 400kg/t, xylene 300kg/t. |
