Abstract
To evaluate the security of fluthiacet - methyl to ecological environment, its residue and digestion in com and soil were studied by field trial. After extracted with acetonitrile and cleaned up by GPC, it was determined by GC - ECD. The results showed that good linear appeared in the range of 0.031 - 8 jig/ml of fluthiacet - methyl with the correlation coefficient as 0.9997. The fortified recovery ranged from 89.63% to 106.66% with the relative standard deviation of 2. 04% ~ 7. 98%. The half life of fluthiacet - methyl was 3.2 -3.5 days in corn and 2.1 ~3. 1 days in soil respectively, and it could be digested more than 90% on the 5th day for corn and the 7th day for soil after application. When sprayed one time with 7.5 g a. I. /hm2 and 11.25 g a. I./hm2 of 5% fluthiacet - methyl EC respectively, the final residue in com was below 0. 001mg/kg on the 70th and 91st day after application. All the results indicated that the gas chromatography method was accurate and reliable for detection of fluthiacet - methyl. The detected residue of fluthiacet - methyl in corn and soil was less than the maximum residue level (0.01 nig/kg) of USA and Japan, so it could not pollute com and soil.关键词
