  <dc:description>&lt;p&gt;&lt;span&gt;A high‐performance liquid chromatography (HPLC) procedure that is rapid, specific, and sensitive (limit of detection &amp;lt;0.005 mg/liter) was developed for monitoring application and degradation rates of rotenone. For analysis, a water sample is buffered to pH 5 and injected through a Sep Pak(R) C&lt;/span&gt;&lt;sub&gt;18&lt;/sub&gt;&lt;span&gt;&amp;nbsp;disposable cartridge. The cartridge adsorbs and retains the rotenone which then can be eluted quantitatively from the cartridge with a small volume of methanol. This step effectively concentrates the sample and provides sample cleanup. The methanol extract is analyzed directly by HPLC on an MCH 10 reverse‐phase column; methanol: Water (75:25, volume : Volume) is the mobile phase and flow rate is 1.5 ml/minute. The rotenone is detected by ultraviolet spectrophotometry at a wavelength of 295 nm.&lt;/span&gt;&lt;/p&gt;</dc:description>
