Abstract EN
Indoxacarb is a broad-spectrum insecticide and widely used in agriculture.
The dissipations and residues of indoxacarb were researched at three different field sites in Beijing, Hunan, and Zhejiang provinces in China.
Analytical methods for determining the residue of indoxacarb in paddy water, paddy soil, rice straw, rice hull, and brown rice were described.
Indoxacarb residues were extracted from samples, cleaned up by solid phase extraction, and determined by high-performance liquid chromatography coupled with tandem mass spectrometry in the selected ion monitoring mode.
The recoveries in paddy water, paddy soil, rice straw, rice hull, and brown rice matrices at three spiking levels ranged from 79.7% to 98.3%, respectively.
The field and environmental conditions would affect the dissipations and residues of indoxacarb.
The time to dissipate 50% of indoxacarb in paddy water, paddy soil, and rice straw was less than 9 days.
The terminal residues obtained from Beijing at preharvest interval of 14 and 21 days were higher than the maximum limit of European Union.
Therefore, a dosage of 24 g a.
i.
ha−1 at 28 days preharvest interval with 3 spraying times was recommended.
Such accumulation of measured data is necessary to provide guidance for the proper and safe use of this pesticide.
