甲基异柳磷等四种农药在土壤薄板上的移动性能

The mobility of four pesticides in soil TLC system

在室内模拟条件下，研究了４种农药在土壤薄板上的移动性能。结果表明，甲基异柳磷与嘧啶氧磷属不易迁移的Ⅱ级农药；克草胺属中等迁移性的Ⅲ级农药；单甲脒属可移动性农药。

Under simulated conditions,the mobilities offour pesticides were studied in soiI TLC system,The resultsshow that methyl-ISP and Pyrimyxthion are immobile and be-long to grade Ⅱ pesticides propachlor is intermediate and be-longs to grade Ⅲ pesticide;and monocarboxoldehyde is mo-bile.
