| 摘 要： | 在根结线虫病严重发生的辣椒大田，采用了9种技术措施进行防治试验。结果表明，非寄主玉米轮作、90 kg?hm-2 PsbA生防制剂粉剂（DP）和63 kg?hm-2淡紫拟青霉微球剂处理120 d后对2龄幼虫的防治效果分别为50.66%、67.54%和71.47%，施药后150 d对根结线虫病的防治效果分别为44.31%、70.81%和73.99%|但以化学杀线虫剂22.5 kg?hm-2 10%噻唑膦颗粒剂（GR）处理土壤最有效，对2龄幼虫和根结线虫病的防治效果分别为83.12%和85.73%。

| Abstract: | 9 technical measures were tested for controlling pepper（Capsicum annuum L.）root-knot nematode in a serious outbreak pepper field．The results showed that the controlling effects of non-host corn rotation，90 kg?hm-2 PsbA DP and 63 kg?hm-2 paecilomyces lilacinus treatments after 120 days on J2 of pepper root-knot nematode were 50.66%，67.54% and 71.47%，respectively．The root-knot nematode controlling effects were 44.31%，70.81% and 73.99% after drugs applied，respectively．The chemical insecticide 22.5 kg?hm-2 fosthiazate GR treatment was the best with 83.12% of J2 controlling effect and 85.73% of root-knot nematode controlling effect. |
