Field trials evaluated the effect of four plant-based bio-fumigants/stimulants on population levels of G. pallida and the resulting potato yields and quality. Three formulations contained seaweed biostimulants (Algifol, Nutridip and Metastim) and one bio-fumigant containing mustard and chilli pepper extracts (Dazitol). These were compared with the fumigant nematicide Nemathorin and untreated control plots. The effect of G. pallida on growing potato crops was assessed by recording haulm characteristics which indicated that the nematicide treatment gave most protection. Levels of PCN juveniles and migratory nematodes were assessed during the trial. Plots treated with Nemathorin and Dazitol had fewest PCN, whilst the highest number of migratory nematodes occurred in fallow plots. Sixteen weeks after planting the nematicide treatment produced highest yield and tuber numbers. Dazitol treatment produced a lower yield but the largest tubers.
田间试验评估了四种植物源生物熏蒸剂/刺激剂对苍白球孢囊线虫种群数量的影响以及由此产生的马铃薯产量和品质。三种配方含有海藻生物刺激剂（Algifol、Nutridip和Metastim），一种生物熏蒸剂含有芥末和辣椒提取物（Dazitol）。将这些与熏蒸杀线虫剂Nemathorin和未处理的对照地块进行比较。通过记录地上部特征评估苍白球孢囊线虫对生长中的马铃薯作物的影响，这表明杀线虫剂处理提供了最大程度的保护。在试验期间评估了孢囊线虫幼虫和迁移性线虫的数量。用Nemathorin和Dazitol处理的地块中孢囊线虫最少，而迁移性线虫数量最多的是休耕地块。种植16周后，杀线虫剂处理的产量和块茎数量最高。Dazitol处理的产量较低，但块茎最大。
