Abstract
|
|
|
Three herbicides including nitrofen, alachlor and butachlor were applied to farm soils of oil-bearing crops rape, soybean and paddy rice and their residual levels in the soil and seeds were determined by ECD-attached gas chromatograph without hydrolysis.
Applied herbicides were decreased abruptly 2 weeks after application and slowly thereafter, reaching below 10% level while the extent of disappearance varied depending on the herbicides, crops and soil conditions. The herbicides were not detected at all in the seeds of Tested crops within the detection limit of the analytical methods employed.
