噁草酮在棉花和土壤中的残留和降解行为研究
Study on Residue and Degradation of Oxadiazon in Cotton and Soil
摘要
Abstract
To evaluate the use security of oxadiazon on cotton , its degradation dynamics and final resi-dues in cotton leaves , seeds and soil were studied by field experiment and gas chromatography ( GC) in Jinan and Hangzhou .The degradation behaviors of oxadiazon in cotton leaves and soil both conformed to the first -degree degradation dynamics equation .Their degradation half -life periods were 4.6~5.5 days and 54.6~71 .5 days respectively .The final residual mass fraction of oxadiazon in cotton seeds was lower than the limit of detection ( LOD) of 0.01 mg/kg and the maximum residue limit ( MRL) of 0.1 mg/kg.It was suggested to spray oxadiazon 1 time with the dosage of 180 g/hm2 in contton field.关键词
