摘　　要：为了验证褐球固氮菌YKT41和越南伯克霍尔德氏菌B418对茄子根结线虫病的防治作用,进行了田间防治效果试验。结果表明,在使用30.0 kg/hm2微生物制剂(活菌数≥20×108 cfu/g)的情况下,YKT41及B418活菌制剂的防治效果分别达到了72.8%和75.6%,增产效果分别达到了14.6%和12.7%,具有良好的推广使用价值。试验还表明,该微生物菌剂主要以活体微生物起作用,灭活后使用效果较差,因此一定要在保质期内使用。We performed the field efficacy test of Azotobacter chroococcum YKT41 and Burkholderia vietnamiensis B418 to prove their biocontrol of eggplant root-knot nematode disease. Results show that the control efficacy of YKT41 and 13418 is 72.8% and 75.6%, yield increased by t4.6% and 12.7%, under the condition of dosage employment of 2. 0kg/667m^2 These biocontrol agents therefore have better generalization value. Their activity depends on living microbe, and their activity sharply declines after no living microbe. Both biocontrol agents therefore must be employed within the guarantee period.
