应用根结线虫病区采集的土壤样本中 2龄幼虫体内分离筛选出来的致病菌株 (用代号为 N1N2 表示 )混合菌液对香蕉根结线虫病进行田间防治试验 ,单用 N1N2 混合菌液 (浓度 4 .1× 10 10 个菌 /ml)防效可达 86 .0 1% ;加入适量增效剂能提高防治效果达 94 .35%。 N1N2 混合菌液对香蕉根结线虫病的防效与目前生产上应用的 2 4 .5%北农爱福丁乳油的杀线效果相当
The root-knot nematode disease zone collected soil samples from the second instar larvae isolated from the pathogenic bacteria strains (codenamed N1N2 said) mixed liquid banana root knot nematode disease prevention and control of the field, alone with N1N2 mixed bacteria solution ( Concentration of 4.1 × 10 10 bacteria / ml) control effect of up to 86.01%; adding proper synergist can improve the control effect of 94.35%. The control effect of N1N2 mixed solution on banana root-knot nematodes was equivalent to that of the currently applied 2.4% BeiNong ErfoFuding EC
