Pesticide Residue of Two New Pesticide Agents in Cabbage

20% miman and 5% ruijingte suspension agents were sprayed in cabbage field to investigate the pesticide residue in cabbage plant. The results show that the tested pesticide agents are of lower residue and long effective period, which can replace some pesticide agents with high poison and residue. The residue extracted by methyl alcohol and acetonitrile can be determined by gas chromatograph and liquid chromatograph.
