ENVIRONMENTAL FATE
The low vapor pressure of 1.0×10-7 mmHg indicates that this insecticide is nonvolatile. In addition, the low Henry's law constant of 6.5×10-11 atm m3/mole, indicates that it has low volatility from water. Therefore, it is unlikely to be dispersed in air over a large area from volatilization. There is a possibility for drift when imidacloprid-treated plant materials are dispersed by planting equipment.The hydrolysis half-life of imidacloprid can range from 33–44 days at pH 7 and 25ºC. The aqueous photolysis half-life is less than 3 hours. Imidacloprid has a photolysis half-life of 39 days at the soil surface, with a range of 26.5-229 days when incorporated into the soil. Persistence in soil allows for continual availability for uptake by plant roots. The combination of low Koc between 132-310 and high water solubility of 514 ppm suggests a potential to leach to ground water.
Usage: Etofenprox is a pyrethroid derivative which is used as an insecticide. Mitsui Chemicals Agro Inc. is the main manufacturer of the Chemical. It is also used as an ingredient in flea medication for cats.
Application: Control of rice water weevils, skippers, leaf beetles, leafhoppers, planthoppers, and bugs on paddy rice; and aphids, moths, butterflies, whitefly, leaf miners, leaf rollers, leafhoppers, thrips, borers, etc. on pome fruit, stone fruit, citrus fruit, tea, soya beans, sugar beet, brassicas, cucumbers, aubergines, and other crops. Also used to control public health pests, and on livestock. Etofenprox 10% SC 120-150 g/ha can be used to control rice hopper in rice, 45-60g/ha can be used to control cabbageworm in cabbage, 33-50 mg/kg can be used to control pine caterpillar in forest.
