摘要

Alachlor (CAS No. 15972-60-8) was developed by Monsanto Company (USA) and introduced in 19t)7 for pre-emergence or pre-plant control of broad spectrum of grass, sedge and broad-leaf weeds in corn, soybeans, dry beans, cotton, grain sorghum, sunflowers, peanuts and other crops. Ramesh et al. (2002) investigated the dissipation of alachlor in soil and plant in field condition (cotton cropping system), and in soil, water and fish in simulated model ecosystem. At harvest, cotton lint and seed samples were found to contain alachlor well below the detectable level. However, trace amounts of residues were found in cotton oil. The green leafy vegetable samples did not show any toxic symptoms of alachlor residues. The objectives of this research are the concise enumeration of the gas-liquid chromatographic (GC-ECD) separation methods used for the determination of residual fate, dissipation pattern and degradation behaviour of alachlor in maize crop and in its soil substrates.
