摘　　要：室内药效试验表明 :麦根宁 号、敌力脱对小麦根腐病菌的生长均有良好的抑制作用。麦根宁 号稀释30 0倍时 ,平均抑菌圈直径最大 ;敌力脱稀释 80 0倍时 ,平均抑菌圈直径最大。同时 ,麦根宁 号、敌力脱 ,麦根宁 号 ,粉锈宁对小麦全蚀病菌生长也有明显的抑制作用。粉锈宁 ,麦根宁 、 号在稀释 10 0 0 0倍时 ,抑菌率均达10 0 %;敌力脱在稀释 15 0 0 0倍时 ,平均抑菌率仍达 89.7%。A laboratory test showed that Maigenning (MGN) and Dilituo (DLT) greatly inhibited the pathoegn growth of wheat common rot (Bipol aris Sorokiniana).The average diameter of the inhibition circle reached the maximum with 300 times diluted MGN and 800 times diluted DLT.Meanwhile MGNⅠ?Ⅱ,DLT and Fenxiuning were also effective on wheat take-all pathogens.With 10,100 times dilutions of FXN,MGNI andⅡ,inhibitation rate on pathogen were up to 100%,and with 15,000 times dilution of DLT it was up to 89.7%.
