Degradation of fenpropathrin, phoxim and their mixture by soil microbes

Abstract

Abstract: The degradation rates of fenpropathrin, phoxim and their mixture in un-sterilized soil were much quicker than those in sterilized soil, which indicated that soil microorganisms played a significant role in the degradation process in soil. The half life (T_0.5) in un sterilized soil was 56.2 d for fenpropathrin, 57.8 d for mixed fenpropathrin, 48.2 d for phoxim, and 41.7 d for mixed phoxim. The corresponding half life (T_0.5) in sterilized soil was 135.1 d, 147.3 d, 123.6 d, and 126.2 d, respectively. There were no significant differences for degradation rates between single use and mixed use of fenpropathrin and phoxim.
