Abstract
A field experiment was conducted at the Shenyang experimental station of ecology, Northeast China, to
determine the response of soil nematode communities to agrochemical applications. Four treatments
were compared including the control (CK, no agrochemicals applied), herbicide acetochlor (A),
nematicide carbofuran (F) and the combination of acetochlor and carbofuran (AF). The obtained results
indicated that the agrochemical applications could influence the soil nematode communities. In the
treatments with acetochlor and/or carbonfuran, the abundances of total nematodes and plant-parasitic
nematodes were reduced, and those of bacterivores decreased obviously at the 8th week. Forty-two
nematode genera were identified, and Acrobeloides, Pratylenchus and Helicotylenchus were dominant
and demonstrated different susceptibilities to agrochemical treatments. No significant sampling date
and treatment effects were observed in the values of enrichment index (EI) and channel index (CI).
However, the basal index (BI) and structural index (SI) were more suitable for indicating the soil
conditions with different agrochemicals in this study, and higher BI and lower SI could indicate poor
ecosystem health.
