A field experiment Was conducted to reveal the dissipation rate and residue analysis of difenoconazole by gas chromatography in cucumbers and soil.Difenoconazole degraded more rapidly in cucumbers than in soil.The half-lives in cucumbers was 6.46～7.21d,and in the soil was 8.77～9.84d.When the cucumbers were treated by 10% difenoconazole,WG at recommended dose（125.0g a.i./hm2） three times,on day 7 after the last application the final residue of difenoconazole in the cucumbers and soil was lower than the maximum residue limit（MRL,0.1mg/kg） f...
