摘要

A variety of macroelement and microelement compounds were tested against the soybean cyst nematode (SCN), Heterodera glicines, in vitro and in vivo on soybean. In vitro, KH_2PO_4 was the best compound to reduce the number of surviving J2 and achieve the lowest value of LC50 (0.01M) and LC90 (0.03M) among the macroelement treatments. Almost all the tested compounds significantly inhibited the hatching of SCN, except for ZnSO_4-7H_2O. Among the microelement treatments, FeCl_3-6H_2O was the best one toinhibit J2 survival with the lowest value of LC50 (0.0004M) and LC90 (0.001M). All the tested compounds significantly inhibited the hatching of SCN and all inhibitions were over 90%. All treatments improved the growth of root and the application of (NH_4)_2HPO_4 gave the best root growth (dry and fresh weighs). In glasshouse, all treatments were significantly effective in reducing the reproduction of SCN. FeC_l3-6H_2O was the best treatment for suppressing cyst production and achieving the highest percentage of nematode inhibition (72.54%).
