采用田间试验方法，研究了戊菌隆农药在棉花和土壤中的残留规律。结果表明，每100kg棉种用戊菌隆75—112．5g（有效成分）拌种，防治棉花苗期病害，戊菌隆在土壤中的残留降解较慢，半衰期7.8—10.1d，施药后35d，降解达90％。收获期土壤、棉叶、棉籽中均未检出戊菌隆

A field test was done to reveal the dynamics of pencycuronresidue in cotton and soil, respectively. 100 kg cottonseeds were mixed with 75—112.5 g (a.i) pencycuron to prevent and cure cotton－seedling diseases. It was discovered that Pencycuron in soil was decomposed slowly with its half－lives were 7.8—10.1 days, while 90％ of pencycuron was not decomposed after 35 days of treatment. The residue of pencycuron in cottonleaf、 cottonseed and soil samples were not detected at harvest period
