Number of Pratylenchus spp. (primarily P. penetrans) were recorded at planting in experimental potato plots over a 9-year period at one location on Prince Edward Island. Tuber yields of 'Superior' and 'Russet Burbank' potatoes in plots treated with aldicarb were compared with yields in adjacent untreated plots. There was a linear relationship between the number of root lesion nematodes at planting and tuber yield increases after treatment for Superior, but not for Russet Burbank (P < 0.05). When counts of root lesion nematodes were greater than 500/kg dry soil, however, the tuber yields of Russet Burbank increased in treated plots. Additional trials at other locations and the inclusion of other cultivars are needed to make numerical relationships of this type available to a nematode advisory service.
在爱德华王子岛的一个地点，对实验马铃薯地块在9年时间里种植时的短体线虫属（主要是穿刺短体线虫）数量进行了记录。将用涕灭威处理地块中“超级”和“褐皮伯班克”马铃薯的块茎产量与相邻未处理地块的产量进行了比较。对于“超级”品种，种植时根腐线虫数量与处理后块茎产量增加之间存在线性关系，但对于“褐皮伯班克”品种则不存在（P<0.05）。然而，当根腐线虫数量大于500条/千克干土时，处理地块中“褐皮伯班克”的块茎产量会增加。需要在其他地点进行更多试验并纳入其他品种，以便线虫咨询服务机构能够利用这类数值关系。
