A field supervised experiment was conducted to reveal dynamics of cypermethrin in soil and litchi fruit,respectively.The residues of cypermethrin in soil and litchi were determined by gas chromatography.The results of two years' study showed that cypermethrin residues in both soil and litchi fruit disappeared rapidly under field conditions.Its half-lives in soil and litchi were from 8.6 to 9.6 days and from 10.4 to 16.4days,respectively.The final residues of the cypermethrin in soil and litchi at 7th or 10th day after last application ranged from 0.003 to 0.06 mg·kg-1 and 0.0044 to 0.0165 mg·kg-1(litchi pulp) which were less than 0.5 mg·kg-1.
