Isotianil (3,4-dichloro-2'-cyano-1,2-thiazole-5-carboxanilide) is a new plant-activating pesticide. Usage of the pesticide was approved for rice fields in 2010 and its production increased 400 times (2 × 10(4) kg) in the next year. In this work, a method for determining isotianil in brown rice and rice field soil was investigated for the first time. Isotianil was extracted by supercritical fluid extraction and measured by gas chromatography/mass spectrometry. Isotianil was successfully analyzed with good recoveries (95.1-99.3%) even from soil samples with strong adsorption of pesticides.
噻酰菌胺（3,4 - 二氯 - 2'- 氰基 - 1,2 - 噻唑 - 5 - 甲酰苯胺）是一种新型植物激活型农药。该农药于2010年被批准用于稻田，次年其产量增长了400倍（2×10⁴千克）。在本研究中，首次对糙米和稻田土壤中噻酰菌胺的测定方法进行了研究。采用超临界流体萃取法提取噻酰菌胺，并用气相色谱/质谱法进行测定。即使是对农药有强烈吸附作用的土壤样品，噻酰菌胺也能成功分析，回收率良好（95.1 - 99.3%）。
