83-79-4 - Nature

• Colorless crystal, melting point 1 63 ℃, 1 81 ℃ (double crystal), vapor pressure <1mPa( 20 ℃).  From the molecular structure, there are different optical isomers, natural products are levorotatory, optical rotation (benzene)- 255. , It will be racemized in case of alkali.  Easy oxidation, in light, air, water, alkaline conditions will accelerate the oxidation, and lose insecticidal activity, dry conditions more stable.  Difficult to dissolve in water (10 mg/L,1 00 ℃), also difficult to dissolve in ether, alcohol, petroleum ether and carbon tetrachloride, soluble in acetone, carbon disulfide, ethyl acetate and chloroform• dosage form single dose 2.5%, 7.5% rotenone cream, 3.  5%, 4% hypertonic rotenone EC;  18%, 21% sinomenine · fish Endo EC, 1.  3%, 2.5%, 7.5% Cyanogen · fish Vine EC, 25% amine · fish Vine EC, 25% enemy · fish Vine EC, 1.  8% avix, 5% pyrethrins, etc.

83-79-4 - Preparation Method

in the root of 15 genera of legume, the most important species are the genus of the genus of the genus of the genus of the genus of the genus and the genus of the genus of the genus of the genus, the main species are the Derris (fur) china, Derris chinensis, Peru spindle nut Bean (Lonch-ocarpus utilis) and Brazil spindle nut Bean (Loncho-carpus urucu). Can be directly processed into powder, can also be processed into powder extract, water, emulsifiable concentrate use. 

83-79-4 - Use

Rotenone is a selective plant-derived insecticide/acaricide that inhibits glutamate dehydrogenase in nerve and muscle tissue, acting as a contact and gastric poison. The insecticidal spectrum is wide, and it is effective for many kinds of pests, such as Lepidoptera, Hemiptera, Coleoptera, Diptera, Hymenoptera, ptera, tick and mite. In the light of rotenone easily oxidized to hydrorotenone and lost insecticidal activity. Mainly used for vegetables, fruit trees, tea trees, flowers and other crops to control a variety of aphids, mites, shrimp, melon flies, blue Spodoptera exigua, Spodoptera litura, thrips, yellow stripe jumping nail, yellow gourd, twenty-eight star, tea worms, tea geometrid, can also be used to control health pests, such as mosquitoes, flies, fleas, lice and so on.

83-79-4 - Safety

• The acute oral LD50 of rats is 132-1500mg/kg, the acute oral LD50 of mice is 350mg/kg, and the acute percutaneous LD50 of rabbits is 940mg/kg. Rotenone is moderately toxic to humans and animals, highly toxic to aquatic organisms such as fish and silkworm, and low toxic to bees.
