Chapter three is the degradation of Abamectin in soils. The results show:(1) The decomposition of Abamectin is fastest in Aquic Cambosols while slowest in Udic Cambosols in five kinds of different soils.(2) Organic matter content in soil is the most important factor which influences the degradation half-life of Abamectin in soil, and their relative coefficient arrives at 0.9323, but pH value, total nitrogen, CEC and field maximum moisture capacity correlate little.(3) Soil organic matter, soil temperature and pesticide concentration can obviously affect Abamectin degradation in soil, in addition, the degradation half-life of Abamectin in sterilized soil is far more than that in non-sterilized soil, which maybe contributes to microorganism in soil. Chapter four is the microbial degradation of Abamectin.
